Definitions
- the disclosure relates to a server for predicting the infection risk level of pathogen in a target area using molecular diagnostic test data, a method therefor, and a non-transitory computer-readable storage medium thereof.
- Infections caused by various pathogens such as respiratory, digestive, and sexually transmitted diseases that occur in the human body may spread through various infection routes.
- PCR real-time polymerase chain reaction
- the level of risk of infection with a pathogen in a specific area is predicted based only on molecular diagnostic test data in the specific area.
- the method for predicting the infection risk level of a pathogen in a specific area does not reflect the infection characteristics of the pathogen because it does not use molecular diagnostic test data for other areas or consider the infection risk level of the pathogen in other areas.
- a server connected with a communication network and predicting an infection risk level of a pathogen in a target area using molecular diagnostic test data.
- the server comprises a communication unit receiving the molecular diagnostic test data for the pathogen in the target area and receiving at least one of molecular diagnostic test data for the pathogen in a surrounding area which is likely to spread the pathogen to the target area or an external infection risk level of the pathogen in the target area, the external infection risk level of the pathogen being an infection risk level of the pathogen in the surrounding area, and a processor determining an internal infection risk level of the pathogen in the target area from the molecular diagnostic test data in the target area, determining the external infection risk level of the pathogen in the target area from the molecular diagnostic test data in the surrounding area when only the molecular diagnostic test data in the surrounding area of the molecular diagnostic test data in the surrounding area or the external infection risk level of the pathogen in the target area is received, and predicting a combinatorial infection risk level of the pathogen in the target area using the internal infection risk level of the pathogen in the target area, the external infection risk level of the pathogen, and a first possibility of spreading in which the pathogen is to spread
- a method for predicting an infection risk level of a pathogen in a target area using molecular diagnostic test data is provided.

Description
The disclosure relates to a server for predicting the infection risk level of pathogen in a target area using molecular diagnostic test data, a method therefor, and a non-transitory computer-readable storage medium thereof.
Infections caused by various pathogens, such as respiratory, digestive, and sexually transmitted diseases that occur in the human body may spread through various infection routes.
It is very important to control these infections and to identify the causative pathogen for proper patient management. Pathogen testing for most infections has grown rapidly with the development of molecular diagnostic technology, especially real-time polymerase chain reaction (PCR). Real-time PCR is more sensitive than traditional methods and may detect a variety of pathogens simultaneously and quickly.
Recently, a real-time PCR test is essential to quickly identify the infection of SARS CoV-2, a respiratory virus that is prevalent around the world and to minimize its spread.
Not only does it provide information regarding the presence or absence of pathogens of interest in a specific subject (whether infected or not) and the infection rate of the pathogens of interest in a population, but molecular diagnostic test data obtained by such a real-time PCR test also helps identify mutations of pathogens of interest or enhance test reagents and methods.
Due to the nature of the infection with a pathogen, when a specific subject in a specific area is infected with a specific pathogen, the risk of infection with the pathogen also increases for subjects in other areas geographically adjacent to or related to the specific area.
However, the level of risk of infection with a pathogen in a specific area is predicted based only on molecular diagnostic test data in the specific area. The method for predicting the infection risk level of a pathogen in a specific area does not reflect the infection characteristics of the pathogen because it does not use molecular diagnostic test data for other areas or consider the infection risk level of the pathogen in other areas.
Accordingly, there is a need for a device and method for predicting the infection risk level of a pathogen in a specific area using molecular diagnostic test data in other areas adjacent to the specific area or considering the infection risk level of the pathogen in the other areas.

FIG. 2 is a view of a configuration of the management server of FIG. 1. FIGS. 3 to 5 illustrate examples of a target area and surrounding areas determined by a processor of the management server of FIG. 1.
Referring to FIG. 2, the management server 130 is a server that is connected with the communication network 110 and predicts the infection risk level of the pathogen in the target area using molecular diagnostic test data.
The management server 130 includes a communication unit 132 that communicates with a terminal or another server through the communication network 110, a processor 134 controlling the management server 130, and a memory 136 storing data.
The communication unit 132 receives, from the first terminal or another first server, molecular diagnostic test data D1 in the target area for the pathogen. The memory 136 stores the molecular diagnostic test data D1 in the target area received from the communication unit 132.

The nucleic acid amplification reaction of a pathogen may be a nucleic acid amplification method that amplifies a nucleic acid through repetition of a series of reactions with or without a temperature change.
The nucleic acid amplification reaction may be a nucleic acid amplification method that amplifies a nucleic acid through repetition of a series of reactions with or without a temperature change. For example, amplification of nucleic acids may be carried out according to various primer-involved nucleic acid amplification methods known in the art, specifically, by polymerase chain reaction (PCR) (U.S. Pat. Nos. 4,683,195, 4,683,202 and 4,800,159). Other examples include ligase chain reaction (LCR) (U.S. Patent Nos. 4,683,195 and 4,683,202; PCR Protocols: A Guide to Methods and Applications (Innis et al., eds, 1990)), strand displacement amplification (SDA)) (Walker, et al. Nucleic Acids Res. 20(7):1691-6 (1992); Walker PCR Methods Appl 3(1):1-6 (1993)), transcription-mediated amplification (Phyffer, et al., J. Clin. Microbiol. 34:834-841 (1996); Vuorinen, et al., J. Clin. Microbiol. 33:1856-1859 (1995)), nucleic acid sequence-based amplification (NASBA) (Compton, Nature 350(6313):91-2 (1991)), rolling circle amplification (RCA) (Lisby, Mol. Biotechnol. 12(1):75-99 (1999); Hatch et al., Genet. Anal. 15(2):35-40 (1999)) and Q-beta Replicase (Lizardi et al., BiolTechnology 6:1197 (1988)).
The medical data may include at least one of questionnaire information, medication information, treatment methods, re-infection status, symptoms, heritability, treatment service code, examination institution type code, and past medical history code.
Referring to Table 3, the molecular diagnostic test data may further include information regarding the subject. For example, if the subject is a human, the molecular diagnostic test data may further include personal information for the subject. The subject's personal information may include at least one of the subject's nationality, age, sex, blood type, location (residence), eating habits, working environment, family history, movement information, smoking status, drinking habits, exercise, pregnancy status, and specific information.
Subject's personal information |
Subject's nationality, age, gender, blood type, location (residence), eating habits, working environment, family history, movement information, smoking status, drinking habits, exercise, pregnancy status, and specific information |
When the subject is an animal, the molecular diagnostic test data may further include the animal's sex, age, habitat, diet, and personal information for the animal's owner. The molecular diagnostic test data may further include the type, collection date and place of the sample, test time, and test place.
Referring back to FIGS. 2 and 3, the processor 134 predicts a combinatorial infection risk level COM of the pathogen in the target area using the internal infection risk level α1 of the pathogen in the target area, the external infection risk level β1 of the pathogen in the target area, and a first possibility of spreading γ1 in which the pathogen is to spread from the surrounding area to the target area.
As an example, the surrounding area may be (i) an area geographically adjacent to the target area or (ii) an area that is traffic-wise, economically, socially, and/or historically related to the target area. As used herein, when A is "adjacent to" B, A may be adjacent to B not only geographically but also traffic-wise, economically, socially, and/or historically.
First, the processor134 determines the internal infection risk level α1 of the pathogen in the target area from the molecular diagnostic test data D1 in the target area.
As an example, when determining the internal infection risk level α1 of the pathogen in the target area, the processor 134 may determine the internal infection risk level α1 of the pathogen in the target area using the positive result value (e.g., the positive number or positive rate) of the pathogen obtained from the molecular diagnostic test data D1 in the target area of Tables 1 to 3 and, optionally, the load of the pathogen.
As another example, when determining the internal infection risk level α1 of the pathogen in the target area, the processor 134 may determine the internal infection risk level α1 of the pathogen in the target area further using pathogen-specific risk factors in the target area.
The pathogen-specific risk factors may include at least one of the transmissibility or the propagability, transmission speed and route, survival and/or proliferation conditions, mutation rate, lethality, incubation period, reinfection rate, animal-human cross infection, and/or drug resistance of the pathogen. The transmissibility refers to the ability of the nucleic acid introduced into the cell by infection or artificial method to, after replication, form infectious particles or a complex equivalent thereto and propagate to separate cells. Transmission route refers to the transmission path of the pathogen and may be divided into droplet transmission, air transmission, and contact transmission (direct or indirect). Survival and/or proliferation conditions are factors for an environment in which pathogens may proliferate, including the humidity, temperature, or surface of the place where the pathogen is located. This pathogen-specific risk factors may be known information or may be information newly identified by the molecular diagnostic data of Tables 1 to 3.
As another example, when determining the internal infection risk level α1 of the pathogen in the target area, the processor 134 may further use the preventive treatment factors of the target area to determine the internal infection risk level α1 of the pathogen in the target area.
The preventive treatment factors may include the presence of a prophylaxis, the presence of a therapy, the efficacy of the prophylaxis, the efficacy of the therapy, and cure rate of the prophylactic therapy, and/or the level of quarantine for the target area for infection of the pathogen. This preventive treatment factors may be known information or may be information newly identified by the molecular diagnostic data of Tables 1 to 3. In particular, the presence of a prophylaxis may include the presence of a vaccine against the pathogen, the presence of a diagnostic kit for testing the pathogen, the number of molecular diagnostic tests per unit population, the number of molecular diagnostic tests per unit population relative to the positive rate, the prevalence of masks. The presence of a therapy may include the presence or absence of a treatment facility, the number of treatment facilities per unit population (e.g., number of isolation treatment beds per unit population), and the number of medical personnel per unit population.
As another example, when determining the internal infection risk level α1 of the pathogen in the target area, the processor 134 may determine the internal infection risk level α1 of the pathogen in the target area by using pathogen-specific risk factors alone or preventive treatment factors alone for the target area.
Further, the processor 340 may determine the internal infection risk level α1 of the pathogen in the target area depending on a pathogen-specific risk factor, e.g., whether the pathogen is a class 1 transmissible disease pathogen or a class 2 transmissible disease pathogen, together with the positive result value of the particular pathogen and optionally the load of the pathogen.
Even with the same positive result value of the specific pathogen and optionally the same load of pathogen, the internal infection risk level α1 of the pathogen in the target area may be relatively high if the pathogen is the class 1 transmissible disease pathogen and may be relatively low if the pathogen is the class 2 transmissible disease pathogen.
When the processor 134 determines the internal infection risk level α1 of the pathogen in the target area using at least two of the positive result value of the pathogen in the target area and optionally, the load of the pathogen, the pathogen-specific risk factors and the preventive treatment factors, and the processor 134 may determine the internal infection risk level α1 of the pathogen in the target area by comprehensively considering two or more determination factors.
The processor 134 may score, or divide into two or more infection risk level grades, the internal infection risk level of the pathogen for use in predicting the combinatorial infection risk level of the pathogen in the target area.
The processor 134 may score the internal infection risk level α1 of the pathogen as an absolute value. For example, when the processor 134 scores the internal infection risk level α1 of the pathogen in the target area using the positive rate, which is one of the positive result values of the pathogen, the processor 340 may determine "0.5" points for a positive rate of the specific pathogen of 2%, "1" point for a positive rate of the specific pathogen of 3.5%, and "2" points for a positive rate of the specific pathogen exceeding 5%. As another example, when the processor 134 scores the internal infection risk level α1 of the pathogen in the target area using the positive number, which is one of the positive result values of the pathogen, the processor 340 may determine "0.5" points for a positive number of the specific pathogen not less than 1 and less than 50, "1" point for a positive number of the specific pathogen not less than 50 and less than 100, and "2" points for a positive number of the specific pathogen not less than 100.
The processor 134 may divide the internal infection risk level α1 of the pathogen into two or more grades (stages). For example, the pathogen infection risk level may be classified into two stages, e.g., high (dangerous) and low (not dangerous), three stages, e.g., high, medium, and low, or N stages, e.g., risk I stage, risk II stage,..., risk N stage.
For example, when the processor 134 determines the infection risk level of the pathogen in the target area based on the positive rate of the pathogen, the processor 340 may divide it into the risk I stage when the positive rate of a specific pathogen is 2% to 3%, the risk II stage when the positive rate is 3% to 5 %, and the risk III stage when the positive rate is more than 5%. As another example, when the processor 134 determines the infection risk level of the pathogen in the target area using the positive number of the pathogen, the processor 340 may divide it into the risk I stage when the positive number of the specific pathogen is not less than 1 and less than 50, the risk II stage when the positive number is not less than 50 and less than 100, and the risk III stage when the positive number is not less than 100.
Referring back to FIGS. 2 and 3, the communication unit 132 may receive the external infection risk level β1 of the pathogen in the target area from the second terminal or another second server. In this case, the processor 134 may predict the combinatorial infection risk level of the pathogen in the target area using the received external infection risk level β1 of the pathogen in the target area.
Further, the communication unit 132 may receive both the molecular diagnostic test data D2 in the surrounding area for the pathogen and the external infection risk level β1 of the pathogen in the target area, from the second terminal or another second server. The processor 134 may predict the combinatorial infection risk level of the pathogen in the target area using the received external infection risk level β1 of the pathogen in the target area.
Even in this case, the processor 134 may calculate the external infection risk level β1 of the pathogen in the target area from the molecular diagnostic test data D2 in the surrounding area and compare it with the received external infection risk level β1 of the pathogen in the target area. When the two are different, the processor 134 may use the average or selected one of the two.
Meanwhile, the communication unit 132 may receive only the molecular diagnostic test data D2 in the surrounding area for the pathogen from the second terminal or another second server.
When the communication unit 132 receives only the molecular diagnostic test data D2 in the surrounding area from the second terminal or the other second server, the processor 134 determines the external infection risk level β1 of the pathogen in the target area from the molecular diagnostic test data D2 in the surrounding area.
For example, the external infection risk level β1 of the pathogen in the target area is the infection risk level of the pathogen in the surrounding area. The external infection risk level β1 of the pathogen in the target area may be the internal infection risk level α2 of the pathogen in the surrounding area.
As another example, the external infection risk level β1 of the pathogen in the target area may be the combinatorial infection risk level COM2 of the pathogen in the surrounding area. In this case, the external infection risk level β1 of the pathogen may be the combinatorial infection risk level COM2 of the pathogen in the surrounding area, predicted using the internal infection risk level α2 of the pathogen in the surrounding area, the external infection risk level β2 of the pathogen in another surrounding area for the surrounding area, and the second possibility of spreading γ2 in which the pathogen is to spread from the other surrounding area for the surrounding area to the surrounding area.
When there are two surrounding areas, the external infection risk level β1 of the pathogen in the target area may be the sum of the internal infection risk levels α2 of the pathogen in the surrounding areas or the sum of the combinatorial infection risk levels COM2 of the pathogen in the surrounding areas.
For example, when the number of the surrounding areas is n, β1= α21+α22+...+ α2n, or β1= COM21+COM22+...+ COM2n.
The processor 134 may determine the infection risk level of the pathogen in the surrounding area in the same manner as (i) determining the internal infection risk level α1 of the pathogen in the target area or (ii) predicting the combinatorial infection risk level COM1 of the pathogen in the target area.
For example, when calculating the combinatorial infection risk levels COM2 of the pathogen in the surrounding areas, the processor 134 may calculate the external infection risk level β2 of the pathogen in the surrounding area in the same manner as calculating the external infection risk level β1 of the pathogen in the target area. When the number of the surrounding areas of a specific surrounding area is n, the external infection risk level β2 of the pathogen in the surrounding area may be β2= α31+α32+...+ α3n or β2= COM31+COM32+...+ COM3n.
Referring back to FIGS. 2 and 3, the processor 134 may score the first possibility of spreading γ1 of the pathogen or divide it into two or more grades to be utilized in predicting the combinatorial infection risk level COM1 of the pathogen in the target area.
The processor 134 may determine the first possibility of spreading γ1 using the distance between the surrounding area and the target area. When the surrounding areas are determined according to the distances from the target area to concentric circles as shown in FIG. 4, the processor 134 may classify the first possibility of spreading γ1 as a specific score or specific grade using the distance between a specific surrounding area and the target area.
For example, the processor 134 may classify the first possibility of spreading γ1 as grade I when the distance between the specific surrounding area and the target area is r1, as grade II when the distance between the specific surrounding area and the target area is r2 (r2>r1), and as grade III when the distance between the specific surrounding area and the target area is r3 (r3>r1).
The distance between the surrounding area and the target area may be a geographic, traffic-wise, economic, social, and/or historical distance from the first area.
The reason why the processor 134 considers the traffic-wise, economic, social, and/or historical distance between the surrounding area and the target area in determining the first possibility of spreading γ1 using the distance between the surrounding area and the target area is that the spread of a specific pathogen is possible between subjects in the areas that are sufficiently apart from each other in geographical distance but have active traffic, economic, social, and/or historical exchanges.
The surrounding area may include a single geographical area or two or more areas geographically separated from each other.
In this case, (i) the area geographically adjacent to the target area may be an area adjacent to the target area in terms of administrative district, an area separated by an infectious disease management entity for infectious disease management, or an area separated by a doctor association or organization considering the degree of proximity of hospitals.
(ii) An area that is traffic-wise, economically, socially, and/or historically related to the target area may be an area where traffic, human or material exchanges with the target area are active.
As an example of the area where traffic and/or human exchanges are active with the target area, if the target area has large-scale factory facilities and workers in the facilities move to a specific area by shuttle buses, the specific area may be the surrounding area although not geographically adjacent to the target area.
For example, as shown in FIG. 5, the surrounding area may correspond to an area that is not geographically adjacent to the target area but is connected with the target area through an infrastructure through which physical exchange is possible, such as a highway. In consideration of not only a specific highway but also the connection of railways or express railways, topographic features, such as rivers, seas, and mountains, inter-city relationships, such as core cities and satellite cities, schools, hospitals, and locations of local governments, the surrounding area may be determined relative to the target area.
Large cities may have many inspection institutions. Thus, the surrounding area may be subdivided into narrow units, and if a specific area with insufficient medical infrastructure has few inspection institutions, the range covered by the surrounding area may be widened, and the surrounding area may be subdivided into wider units.
For example, the target area may be a first hospital and the surrounding area may be a second hospital located within a predetermined radius from the first hospital as shown in FIG. 4. As another example, the target area may be a specific administrative area, and the surrounding area may be another administrative area adjacent to the specific administrative area. As another example, the target area may be a specific country, and the surrounding area may be another country adjacent to the specific country. As another example, if a Russian sailor is infected with a specific pathogen in a specific area of Korea, the target area may be Korea and the surrounding area may be Russia, and vice versa. As another example, the target area may be a specific continent, and the surrounding area may be another continent adjacent to the specific continent.
The processor 134 may calculate the second possibility of spreading γ2 of the pathogen in the surrounding area in the same manner as calculating the first possibility of spreading γ1 of the pathogen in the target area.
The processor 134 may determine, every first period T1, the internal infection risk level α1 of the pathogen in the target area from the molecular diagnostic test data D1 in the target area and predict, every second period T2 different from the first period T1, the combinatorial infection risk level COM1 of the pathogen in the target area using the internal infection risk level α1 of the pathogen in the target area, the external infection risk level β1 of the pathogen in the target area, and the first possibility of spreading γ1.
For example, the first period T1 may be shorter than the second period T2. In other words, the processor 134 may determine the internal infection risk level α1 of the pathogen in the target area, from the molecular diagnostic test data D1 in the target area, in a relatively shorter period. Further, the processor 134 may determine the combinatorial infection risk level COM1 of the pathogen in the target area, in a relatively long period.
For example, the first period T1 may be one day, and the second period T2 may be one week. Accordingly, the processor 134 may determine the internal infection risk level α1 of the pathogen in the target area every day and predict the combinatorial infection risk level COM1 of the pathogen in the target area every week. The processor 134 may predict, for one week, the combinatorial infection risk level COM1 of the pathogen in the target area using, e.g., the average, minimum value, or maximum value of the internal infection risk levels α1 of the pathogen in the target area determined every day for one week.
As another example, the first period T1 may be longer than the second period T1, and as another example, the first period T1 may be the same as the second period T2. When the first period T1 is the same as the second period T2, the processor 134 may predict the combinatorial infection risk level COM1 of the pathogen in the target area using the internal infection risk level α1 of the pathogen in the target area for the same period.
Further, the processor 134 may predict the combinatorial infection risk level COM1 of the pathogen in the target area by giving the same or different weights to the internal infection risk level α1 of the pathogen in the target area, the external infection risk level β1 of the pathogen in the target area, and the first possibility of spreading γ1.
For example, when the respective weights of the infection risk level α1 of the pathogen in the target area, external infection risk level β1 of the pathogen in the target area, and the first possibility of spreading γ1 are kα, kβ, and kγ, the combinatorial infection risk level COM1 of the pathogen in the target area may be represented as in Equation 1 below.
[Equation 1]
COM1= F(α1, β1, γ1, kα, kβ, kγ)
For example, when weighted-averaging the infection risk level α1 of the pathogen, external infection risk level β1 of the pathogen, and the first possibility of spreading γ1 in the target area in Equation 1, the combinatorial infection risk level COM1 of the pathogen in the target area may be represented as in Equation 2.
[Equation 2]
COM1= (kα*α1+ kβ*β1+kγ*γ1)/3
As described above, for comparison between the combinatorial infection risk level COM1 of the pathogen in the target area and each of the infection risk level α1 of the pathogen, external infection risk level β1 of the pathogen, and the first possibility of spreading γ1 in the target area when scoring or grading the infection risk level α1 of the pathogen, external infection risk level β1 of the pathogen, and the first possibility of spreading γ1 in the target area as the same one, the combinatorial infection risk level COM1 of the pathogen in the target area may be calculated using Equation 2, i.e., the weighted average.
Table 4 shows the values resultant from calculating the combinatorial infection risk level COM1 of the pathogen in the target area using Equation 2 when kα=0.8, kβ=0.2, and kγ=0.5.

As another example, when summating the results obtained by multiplying the infection risk level α1 of the pathogen, external infection risk level β1 of the pathogen, and the first possibility of spreading γ1 in the target area by their respective weights in Equation 1, the combinatorial infection risk level COM1 of the pathogen in the target area may be represented as in Equation 3.
[Equation 3]
COM1= kα*α1+ kβ*β1+kγ*γ1
Table 5 shows the values resultant from calculating the combinatorial infection risk level COM1 of the pathogen in the target area using Equation 3 when kα=0.8, kβ=0.2, and kγ=1.

In a case where the communication unit 132 receives only the molecular diagnostic test data D2 in the surrounding area from the second terminal or another second server, and the external infection risk level β1 of the pathogen in the target area is the combinatorial infection risk level COM2 of the pathogen in the surrounding area, the processor 134 may calculate the combinatorial infection risk level COM2 of the pathogen in the surrounding area from the molecular diagnostic test data D2 in the surrounding area, using one of Equations 1 to 3.
The processor 134 may predict the combinatorial infection risk level COM1 of the pathogen in the target area using the internal infection risk level α1 of the pathogen in the target area, the external infection risk level β1 of the pathogen in the target area, and the first possibility of spreading γ1 in which the pathogen is to spread from the surrounding area to the target area, based on an artificial neural network.
For example, all or part of previously stored molecular diagnostic test data is split into a training set and a test set. After a specific deep learning model may be trained with the training set, the combinatorial infection risk level COM of the pathogen in the target area may be predicted using the test set. Thus, the processor 134 may determine the combinatorial infection risk level COM of the pathogen in the target area although no separate determination element is presented.
The processor 134 may determine at least one of the internal infection risk level α2 of the pathogen in the surrounding area, the external infection risk level β2 of the pathogen in the surrounding area, the second possibility of spreading γ2 in which the pathogen is to spread from another surrounding area to the surrounding area, or the combinatorial infection risk level COM2 of the pathogen in the surrounding area, based on the artificial neural network. The server for predicting the infection risk level of a pathogen in a target area using molecular diagnostic test data, according to the above-described embodiments, may predict the infection risk level of a specific area using molecular diagnostic test data in other areas geographically adjacent to, or related to, the specific area, as well as molecular diagnostic test data obtained through a molecular diagnostic test in the specific area, or considering the infection risk level of the pathogen in the other areas.
Therefore, when predicting the infection risk level of a pathogen in a specific area, it is possible to maximally reflect the infection characteristics of the pathogen and enhance the accuracy of the infection risk level of the pathogen in the specific area.
A configuration of the management server 130 that predicts the infection risk level of the pathogen in the target area using molecular diagnostic test data according to an embodiment has been described above with reference to FIGS. 2 to 5. A method for predicting the infection risk level of a pathogen in a target area using molecular diagnostic test data according to another embodiment is described below with reference to FIG. 6.
FIG. 6 is a flowchart of a method for predicting the infection risk level of a pathogen in a target area using molecular diagnostic test data according to another embodiment.
Referring to FIG. 6, a method 200 for predicting an infection risk level of a pathogen in a target area using molecular diagnostic test data according to another embodiment includes the step S210 of receiving data in the target data, the step S220 of receiving data in a surrounding area, the step S230 of determining an internal infection risk level of the pathogen, the step S240 of determining an external infection risk level of the pathogen, and the step S250 of predicting a combinatorial infection risk level of the pathogen.
According to another embodiment, the method 200 for predicting the infection risk level of the pathogen in the target area may be performed by the management server 130 described with reference to FIG. 1 or may be performed by the user terminal 120 and the inspection server 140. Some of the steps may be performed by either the user terminal 120 or the inspection server 140 while the others by the other.
According to another embodiment, in the method 200 for predicting the infection risk level of the pathogen in the target area using the molecular diagnostic test data, the above-described steps may be performed sequentially, repeated for a specific step, or performed in a different order.
Although it is described below with reference to FIG. 2 that the management server 130 performs the method 200 for predicting the infection risk level of the pathogen in the target area using the molecular diagnostic test data according to an embodiment, the disclosure is not limited thereto.
Referring to FIG. 6, the step S210 of receiving the data in the target area receives, from the first terminal or another first server, molecular diagnostic test data D1 in the target area for the pathogen.
The first terminal may be the user terminal 120 located in the target area described above with reference to FIG. 1, and the other first server may be the above-described inspection server 140 located in the target area.
The step S220 of receiving the data in the surrounding area receives at least one of the molecular diagnostic test data D2 in the surrounding area or the external infection risk level of the pathogen in the target area, for the pathogen, from the second terminal or another second server. The external infection risk level of the pathogen may be the infection risk level of the pathogen in the surrounding area, as described above.
The second terminal may be the user terminal 120 located in the surrounding area described above with reference to FIG. 1, and the other second server may be the above-described inspection server 140 located in the surrounding area.
As an example, the step S220 of receiving the data in the surrounding area may receive both the molecular diagnostic test data D2 in the surrounding area and the external infection risk level β1 of the pathogen in the target area, for the pathogen, from the second terminal or another second server.
As another example, the step S220 of receiving the data in the surrounding area may receive only the molecular diagnostic test data D2 in the surrounding area for the pathogen from the second terminal or another second server.
As another example, the step S220 of receiving only the data in the surrounding area may receive the external infection risk level β1 of the pathogen in the target area from the second terminal or another second server.
Referring to Table 1, the molecular diagnostic test data may include result data obtained from a nucleic acid amplification reaction on the pathogen to be detected in the sample obtained from the subject (e.g., a human patient). Further, the molecular diagnostic test data may include medical data for the subject, but the present invention is not limited thereto.
Referring to Table 2, the result data may include the name of the pathogen to be detected and information indicating whether the pathogen is positive/negative. If necessary, the result data may optionally further include the cycle threshold (Ct) value in the nucleic acid amplification reaction of the pathogen.
Referring to Table 3, the molecular diagnostic test data may further include information regarding the subject. For example, if the subject is a human, the molecular diagnostic test data may further include personal information for the subject. The subject's personal information may include at least one of the subject's nationality, age, sex, blood type, location (residence), eating habits, working environment, family history, movement information, smoking status, drinking habits, exercise, pregnancy status, and specific information.
The step S230 of determining the internal infection risk level of the pathogen determines the internal infection risk level α1 of the pathogen in the target area from the molecular diagnostic test data D1 in the target area.
As an example, when determining the internal infection risk level α1 of the pathogen in the target area, it is possible to determine the internal infection risk level α1 of the pathogen in the target area using the positive result value (e.g., the positive number or positive rate) of the pathogen obtained from the molecular diagnostic test data D1 in the target area of Tables 1 to 3 and, optionally, the load of the pathogen.
As another example, when determining the internal infection risk level α1 of the pathogen in the target area, it is possible to determine the internal infection risk level α1 of the pathogen in the target area further using pathogen-specific risk factors in the target area.
The pathogen-specific risk factors may include at least one of the transmissibility, transmission speed and route, survival and/or proliferation conditions, mutation rate, lethality, incubation period, reinfection rate, animal-human cross infection, and/or drug resistance of the pathogen. The transmissibility refers to the ability of the nucleic acid introduced into the cell by infection or artificial method to, after replication, form infectious particles or a complex equivalent thereto and propagate to separate cells. Transmission route refers to the transmission path of the pathogen and may be divided into droplet transmission, air transmission, and contact transmission (direct or indirect). Survival and/or proliferation conditions are factors for an environment in which pathogens may proliferate, including the humidity, temperature, or surface of the place where the pathogen is located. This pathogen-specific risk factors may be known information or may be information newly identified by the molecular diagnostic data of Tables 1 to 3.
As another example, when determining the internal infection risk level α1 of the pathogen in the target area, it is possible to further use the preventive treatment factors of the target area to determine the internal infection risk level α1 of the pathogen in the target area.
The preventive treatment factors may include the presence of a prophylaxis, the presence of a therapy, the efficacy of the prophylaxis, the efficacy of the therapy, and cure rate of the prophylactic therapy, and/or the level of quarantine for the target area for infection of the pathogen. This preventive treatment factors may be known information or may be information newly identified by the molecular diagnostic data of Tables 1 to 3. In particular, the presence of a prophylaxis may include the presence of a vaccine against the pathogen, the presence of a diagnostic kit for testing the pathogen, the number of molecular diagnostic tests per unit population, the number of molecular diagnostic tests per unit population relative to the positive rate, the prevalence of masks. The presence of a therapy may include the presence or absence of a treatment facility, the number of treatment facilities per unit population (e.g., number of isolation treatment beds per unit population), and the number of medical personnel per unit population.
As another example, when determining the internal infection risk level α1 of the pathogen in the target area, it is possible to determine the internal infection risk level α1 of the pathogen in the target area by using pathogen-specific risk factors alone or preventive treatment factors alone for the target area.
Further, in determining the internal infection risk level α1 of the pathogen in the target area, it is possible to determine the internal infection risk level α1 of the pathogen in the target area depending on a pathogen-specific risk factor, e.g., whether the pathogen is a class 1 transmissible disease pathogen or a class 2 transmissible disease pathogen, together with the positive result value of the particular pathogen and optionally the load of the pathogen.
Even with the same positive result value of the specific pathogen and optionally the same load of pathogen, the internal infection risk level α1 of the pathogen in the target area may be relatively high if the pathogen is the class 1 transmissible disease pathogen and may be relatively low if the pathogen is the class 2 transmissible disease pathogen.
In the step S230 of determining the internal infection risk level of the pathogen, when determining the internal infection risk level α1 of the pathogen in the target area using at least two of the positive result value of the pathogen in the target area and optionally, the load of the pathogen, the pathogen-specific risk factors and the preventive treatment factors, it is possible to determine the internal infection risk level α1 of the pathogen in the target area by comprehensively considering two or more determination factors.
The step S230 of determining the internal infection risk level of the pathogen may score, or divide into two or more infection risk level grades, the internal infection risk level of the pathogen for use in predicting the combinatorial infection risk level of the pathogen in the target area.
In the step S230 of determining the internal infection risk level of the pathogen, the internal infection risk level α1 of the pathogen may be scored as an absolute value. For example, when the processor 134 scores the internal infection risk level α1 of the pathogen in the target area using the positive rate, which is one of the positive result values of the pathogen, the processor 340 may determine "0.5" points for a positive rate of the specific pathogen of 2%, "1" point for a positive rate of the specific pathogen of 3.5%, and "2" points for a positive rate of the specific pathogen exceeding 5%. As another example, when the processor 134 scores the internal infection risk level α1 of the pathogen in the target area using the positive number, which is one of the positive result values of the pathogen, the processor 340 may determine "0.5" points for a positive number of the specific pathogen not less than 1 and less than 50, "1" point for a positive number of the specific pathogen not less than 50 and less than 100, and "2" points for a positive number of the specific pathogen not less than 100.
The step S230 of determining the internal infection risk level of the pathogen may divide the internal infection risk level α1 of the pathogen into two or more grades (stages). For example, the pathogen infection risk level may be classified into two stages, e.g., high (dangerous) and low (not dangerous), three stages, e.g., high, medium, and low, or N stages, e.g., risk I stage, risk II stage,..., risk N stage.
For example, when determining the infection risk level of the pathogen in the target area based on the positive rate of the pathogen, the processor 340 may divide it into the risk I stage when the positive rate of a specific pathogen is 2% to 3%, the risk II stage when the positive rate is 3% to 5 %, and the risk III stage when the positive rate is more than 5%. As another example, when the processor 134 determines the infection risk level of the pathogen in the target area using the positive number of the pathogen, the processor 340 may divide it into the risk I stage when the positive number of the specific pathogen is not less than 1 and less than 50, the risk II stage when the positive number is not less than 50 and less than 100, and the risk III stage when the positive number is not less than 100.
The step S240 of determining the external infection risk level of the pathogen determines the external infection risk level of the pathogen using the received molecular diagnostic test data D2 in the surrounding area or the external infection risk level of the pathogen in the target area.
As described above, the step S220 of receiving the data in the surrounding area may receive both the molecular diagnostic test data D2 in the surrounding area and the external infection risk level β1 of the pathogen in the target area, for the pathogen, from the second terminal or another second server.
Even in this case, the step S240 of determining the external infection risk level of the pathogen may calculate the external infection risk level β1 of the pathogen in the target area from the molecular diagnostic test data D2 in the surrounding area and compare it with the received external infection risk level β1 of the pathogen in the target area. When the two are different, the step S240 of determining the external infection risk level of the pathogen may use the average or selected one of the two.
As described above, the step S220 of receiving the data in the surrounding area may receive only the molecular diagnostic test data D2 in the surrounding area for the pathogen from the second terminal or another second server.
In this case, the step S240 of determining the external infection risk level of the pathogen may calculate the external infection risk level β1 of the pathogen in the target area from the molecular diagnostic test data D2 in the surrounding area.
For example, the external infection risk level β1 of the pathogen in the target area is the infection risk level of the pathogen in the surrounding area. The external infection risk level β1 of the pathogen in the target area may be the internal infection risk level α2 of the pathogen in the surrounding area.
As another example, the external infection risk level β1 of the pathogen in the target area may be the combinatorial infection risk level COM2 of the pathogen in the surrounding area. In this case, the external infection risk level β1 of the pathogen may be the combinatorial infection risk level COM2 of the pathogen in the surrounding area, predicted using the internal infection risk level α2 of the pathogen in the surrounding area, the external infection risk level β2 of the pathogen in another surrounding area for the surrounding area, and the second possibility of spreading γ2 in which the pathogen is to spread from the other surrounding area for the surrounding area to the surrounding area.
When there are two surrounding areas, the external infection risk level β1 of the pathogen in the target area may be the sum of the internal infection risk levels α2 of the pathogen in the surrounding areas or the sum of the combinatorial infection risk levels COM2 of the pathogen in the surrounding areas.
For example, when the number of the surrounding areas is n, β1= α21+α22+...+ α2n, or β1= COM21+COM22+...+ COM2n.
The step S240 of determining the external infection risk level of the pathogen may determine the infection risk level of the pathogen in the surrounding area in the same manner as (i) determining the internal infection risk level α1 of the pathogen in the target area or (ii) predicting the combinatorial infection risk level COM1 of the pathogen in the target area.
For example, when calculating the combinatorial infection risk levels COM2 of the pathogen in the surrounding areas, the processor 134 may calculate the external infection risk level β2 of the pathogen in the surrounding area in the same manner as calculating the external infection risk level β1 of the pathogen in the target area. When the number of the surrounding areas of a specific surrounding area is n, the external infection risk level β2 of the pathogen in the surrounding area may be β2= α31+α32+...+ α3n or β2= COM31+COM32+...+ COM3n.
The step S250 of predicting the combinatorial infection risk level of the pathogen predicts a combinatorial infection risk level COM of the pathogen in the target area using the internal infection risk level α1 of the pathogen in the target area, the external infection risk level β1 of the pathogen, and a first possibility of spreading γ1 in which the pathogen is to spread from the surrounding area to the target area.
The step S250 of predicting the combinatorial infection risk level of the pathogen may score the first possibility of spreading γ1 of the pathogen or divide it into two or more grades to be utilized in predicting the combinatorial infection risk level COM1 of the pathogen in the target area.
The step S250 of predicting the combinatorial infection risk level of the pathogen may determine the first possibility of spreading γ1 using the distance between the surrounding area and the target area. When the surrounding areas are determined according to the distances from the target area to concentric circles as shown in FIG. 4, the processor 134 may classify the first possibility of spreading γ1 as a specific score or specific grade using the distance between a specific surrounding area and the target area.
For example, the step S250 of predicting the combinatorial infection risk level of the pathogen may classify the first possibility of spreading γ1 as grade I when the distance between the specific surrounding area and the target area is r1, as grade II when the distance between the specific surrounding area and the target area is r2 (r2>r1), and as grade III when the distance between the specific surrounding area and the target area is r3 (r3>r1).
As an example, the surrounding area may be (i) an area geographically adjacent to the target area or (ii) an area that is traffic-wise, economically, socially, and/or historically related to the target area. As used herein, when A is "adjacent to" B, A may be adjacent to B not only geographically but also traffic-wise, economically, socially, and/or historically.
The distance between the surrounding area and the target area may be a geographic, traffic-wise, economic, social, and/or historical distance from the first area.
The reason for considering the traffic-wise, economic, social, and/or historical distance between the surrounding area and the target area in determining the first possibility of spreading γ1 using the distance between the surrounding area and the target area is that the spread of a specific pathogen is possible between subjects in the areas that are sufficiently apart from each other in geographical distance but have active traffic, economic, social, and/or historical exchanges.
The surrounding area may include a single geographical area or two or more areas geographically separated from each other.
In this case, (i) the area geographically adjacent to the target area may be an area adjacent to the target area in terms of administrative district, an area separated by an infectious disease management entity for infectious disease management, or an area separated by a doctor association or organization considering the degree of proximity of hospitals.
(ii) An area that is traffic-wise, economically, socially, and/or historically related to the target area may be an area where traffic, human or material exchanges with the target area are active.
As an example of the area where traffic and/or human exchanges are active with the target area, if the target area has large-scale factory facilities and workers in the facilities move to a specific area by shuttle buses, the specific area may be the surrounding area although not geographically adjacent to the target area.
For example, as shown in FIG. 5, the surrounding area may correspond to an area that is not geographically adjacent to the target area but is connected with the target area through an infrastructure through which physical exchange is possible, such as a highway. In consideration of not only a specific highway but also the connection of railways or express railways, topographic features, such as rivers, seas, and mountains, inter-city relationships, such as core cities and satellite cities, schools, hospitals, and locations of local governments, the surrounding area may be determined relative to the target area.
Large cities may have many inspection institutions. Thus, the surrounding area may be subdivided into narrow units, and if a specific area with insufficient medical infrastructure has few inspection institutions, the range covered by the surrounding area may be widened, and the surrounding area may be subdivided into wider units.
For example, the target area may be a first hospital and the surrounding area may be a second hospital located within a predetermined radius from the first hospital as shown in FIG. 4. As another example, the target area may be a specific administrative area, and the surrounding area may be another administrative area adjacent to the specific administrative area. As another example, the target area may be a specific country, and the surrounding area may be another country adjacent to the specific country. As another example, if a Russian sailor is infected with a specific pathogen in a specific area of Korea, the target area may be Korea and the surrounding area may be Russia, and vice versa. As another example, the target area may be a specific continent, and the surrounding area may be another continent adjacent to the specific continent.
The step S250 of predicting the combinatorial infection risk level of the pathogen may calculate the second possibility of spreading γ2 of the pathogen in the surrounding area in the same manner as calculating the first possibility of spreading γ1 of the pathogen in the target area.
The step S250 of predicting the combinatorial infection risk level of the pathogen may determine, every first period T1, the internal infection risk level α1 of the pathogen in the target area from the molecular diagnostic test data D1 in the target area and predict, every second period T2 different from the first period T1, the combinatorial infection risk level COM1 of the pathogen in the target area using the internal infection risk level α1 of the pathogen in the target area, the external infection risk level β1 of the pathogen in the target area, and the first possibility of spreading γ1.
For example, the first period T1 may be shorter than the second period T2. In other words, the processor 134 may determine the internal infection risk level α1 of the pathogen in the target area, from the molecular diagnostic test data D1 in the target area, in a relatively shorter period. Further, the processor 134 may determine the combinatorial infection risk level COM1 of the pathogen in the target area, in a relatively long period.
For example, the first period T1 may be one day, and the second period T2 may be one week. Accordingly, the processor 134 may determine the internal infection risk level α1 of the pathogen in the target area every day and predict the combinatorial infection risk level COM1 of the pathogen in the target area every week. The processor 134 may predict, for one week, the combinatorial infection risk level COM1 of the pathogen in the target area using, e.g., the average, minimum value, or maximum value of the internal infection risk levels α1 of the pathogen in the target area determined every day for one week.
As another example, the first period T1 may be longer than the second period T1, and as another example, the first period T1 may be the same as the second period T2. When the first period T1 is the same as the second period T2, the processor 134 may predict the combinatorial infection risk level COM1 of the pathogen in the target area using the internal infection risk level α1 of the pathogen in the target area for the same period.
Further, the step S250 of predicting the combinatorial infection risk level of the pathogen may predict the combinatorial infection risk level COM1 of the pathogen in the target area by giving the same or different weights to the internal infection risk level α1 of the pathogen in the target area, the external infection risk level β1 of the pathogen in the target area, and the first possibility of spreading γ1.
As described above, when the respective weights of the infection risk level of the pathogen in the target area, external infection risk level β1 of the pathogen in the target area, and the first possibility of spreading γ1 are kα, kβ, and kγ, the combinatorial infection risk level COM1 of the pathogen in the target area may be represented as in Equation 1 above.
As described above, when weighted-averaging the infection risk level α1 of the pathogen, external infection risk level β1 of the pathogen, and the first possibility of spreading γ1 in the target area in Equation 1, the combinatorial infection risk level COM1 of the pathogen in the target area may be represented as in Equation 2 above.
As described above, for comparison between the combinatorial infection risk level COM1 of the pathogen in the target area and each of the infection risk level α1 of the pathogen, external infection risk level β1 of the pathogen, and the first possibility of spreading γ1 in the target area when scoring or grading the infection risk level 5 α1 of the pathogen, external infection risk level β1 of the pathogen, and the first possibility of spreading γ1 in the target area as the same one, the combinatorial infection risk level COM1 of the pathogen in the target area may be calculated using Equation 2, ie, the weighted average.
As another example, when summating the results obtained by multiplying the infection risk level α1 of the pathogen, external infection risk level β1 of the pathogen, and the first possibility of spreading γ1 in the target area by their respective weights in Equation 1, the combinatorial infection risk level COM1 of the pathogen in the target area may be represented as in Equation 3 as described above.
In a case where only the molecular diagnostic test data D2 in the surrounding area is received from the second terminal or another second server, and the external infection risk level β1 of the pathogen in the target area is the combinatorial infection risk level COM2 of the pathogen in the surrounding area, the step S250 of predicting the combinatorial infection risk level of the pathogen may calculate the combinatorial infection risk level COM2 of the pathogen in the surrounding area from the molecular diagnostic test data D2 in the surrounding area, using one of Equations 1 to 3.
The step S250 of predicting the combinatorial infection risk level of the pathogen may predict the combinatorial infection risk level COM1 of the pathogen in the target area using the internal infection risk level α1 of the pathogen in the target area, the external infection risk level β1 of the pathogen in the target area, and the first possibility of spreading γ1 in which the pathogen is to spread from the surrounding area to the target area, based on an artificial neural network.
For example, all or part of previously stored molecular diagnostic test data is split into a training set and a test set. After a specific deep learning model may be trained with the training set, the combinatorial infection risk level COM of the pathogen in the target area may be predicted using the test set. Thus, the processor 134 may determine the combinatorial infection risk level COM of the pathogen in the target area although no separate determination element is presented.
The step S250 of predicting the combinatorial infection risk level of the pathogen may determine at least one of the internal infection risk level α2 of the pathogen in the surrounding area, the external infection risk level β2 of the pathogen in the surrounding area, the second possibility of spreading γ2 in which the pathogen is to spread from another surrounding area to the surrounding area, or the combinatorial infection risk level COM2 of the pathogen in the surrounding area, based on the artificial neural network. The method for predicting the infection risk level of a pathogen in a target area using molecular diagnostic test data, according to the above-described embodiments, may predict the infection risk level of a specific area using molecular diagnostic test data in other areas geographically adjacent to, or related to, the specific area, as well as molecular diagnostic test data obtained through a molecular diagnostic test in the specific area, or considering the infection risk level of the pathogen in the other areas.
Therefore, when predicting the infection risk level of a pathogen in a specific area, it is possible to maximally reflect the infection characteristics of the pathogen and enhance the accuracy of the infection risk level of the pathogen in the specific area.
