Referring to fig. 3, fig. 3 is a flowchart illustrating an epidemic prevention and control method according to an embodiment of the present invention, where the method includes the following steps:
step S101, acquiring diagnostic data and contact history data of a plurality of patients, wherein the diagnostic data of each patient comprises the disease onset time of the patient, the contact history data of each patient comprises the contact time, the contact duration and the contact distance of a contact person contacted by the patient, and the contact history data of each patient is acquired by a first terminal used by the patient through a near field communication technology.
In this embodiment, the diagnostic data of the patient includes, but is not limited to, the time of onset, sex, age, and underlying condition of the patient. The contact history data of the patient includes, but is not limited to, the contact time, contact duration, contact distance, contact location, etc. of the contacter with which the patient has contacted. When the patient uses the first terminal 20 with the short-range communication enabled, the first terminal 20 can continuously perform the short-range scanning, and when the distance between the first terminal 20 and another terminal (e.g., the third terminal 40 in fig. 1) with the short-range communication enabled is within a preset range, the first terminal 20 continuously transmits contact history data, such as contact time, contact duration, contact distance, and the like, to the server 10 according to the result of the short-range scanning.
Step S102, determining the contact person who has the contact time earlier than the attack time of the patient and has been diagnosed in the contact persons of each patient as the target contact person of the patient.
In this embodiment, there may be a plurality of contacts for each patient, and the target contact of the patient is one of the plurality of contacts who has a contact time with the patient earlier than the onset time of the patient and has been diagnosed, i.e. the patient has a high probability of being infected by the target contact.
Step S103, determining a duration threshold according to the contact duration of each target contact person with the corresponding patient, and determining a distance threshold according to the contact distance of each target contact person with the corresponding patient.
In the present embodiment, the duration threshold is used for a threshold value of a contact time representing a risk of infection between two contacters, when the contact time of two contacters is greater than the duration threshold, a greater risk of infection is considered to exist, the distance threshold is used for a threshold value of a contact distance representing a risk of infection between two contacters, and when the contact distance of two contacters is greater than the distance threshold, a greater risk of infection is considered to exist.
And step S104, sending the duration threshold and the distance threshold to the second terminal so that the second terminal displays alarm information after detecting that the contact duration with other terminals reaches the duration threshold or the contact distance with other terminals reaches the distance threshold.
In this embodiment, the other terminal may be the third terminal 40 in fig. 1.
In this embodiment, according to the needs of an actual scene, the warning information may also be displayed after the second terminal detects that the contact time with other terminals reaches the time threshold and the contact distance with other terminals reaches the distance threshold.
It should be noted that, in order to avoid unnecessary data transmission, the time length threshold and the distance threshold do not need to be sent to the first terminal 20, because the user corresponding to the first terminal 20 is a patient who has already been diagnosed, at this time, the first terminal 20 does not need to detect the contact time length or the contact distance with other terminals, and it is also not necessary to display the alarm information according to the time length threshold or the distance threshold.
It should be further noted that, in order to more accurately send the alarm information, the server 10 may further obtain whether the user of the other terminal whose contact time with the second terminal 30 reaches the time threshold or the contact distance reaches the distance threshold is a confirmed patient, and if the user is a confirmed patient, send the alarm information with a high risk of infection, otherwise, send the alarm information with a medium risk of infection.
According to the epidemic situation prevention and control method provided by the embodiment of the invention, the contact person is warned in a targeted manner by adopting the time length threshold and the distance threshold determined by the contact history data acquired by near field communication, so that the warning effect is improved.
On the basis of fig. 3, an embodiment of the present invention further provides a specific implementation manner for determining the duration threshold and the distance threshold, please refer to fig. 4, where fig. 4 shows a flowchart of another epidemic prevention and control method provided by the embodiment of the present invention, and step S103 includes the following sub-steps:
and a substep S1031, determining the minimum value of the contact time length of the target contact person and the corresponding patient as a time length threshold value.
In this embodiment, each target contacter corresponds to one patient, and corresponds to one contact duration contacted with the patient, and the minimum value of the contact durations corresponding to all the target contacters is determined as the duration threshold.
In sub-step S1032, the minimum value of the contact distance between the target contact person and the corresponding patient is determined as the distance threshold.
In this embodiment, the determination manner of the distance threshold is similar to that of the duration threshold, and is not described herein again.
It should be noted that, in addition to using the minimum value of the contact time duration or the minimum value of the contact distance corresponding to the target contacter, the time duration threshold may also be determined according to the average value or the variance of the contact time durations corresponding to all the target contacters, or the distance threshold may be determined according to the average value or the variance of the contact distances corresponding to all the target contacters, and these technical solutions are not obtained by those skilled in the art with creative labor, and therefore, are also within the protection scope of the present invention.
In this case, according to the needs of the actual scenario, the contact history data of each target contact and the patient may be taken into account when determining the time length threshold and the distance threshold, or only the target contact with the contact time closest to the onset time of the patient may be taken into account, or only the target contact with the contact time farthest from the onset time of the patient may be taken into account. For example, patient a has 1 target contacter 1, a contact duration of 5 minutes, a contact distance of 2.5 meters, and patient b has 2 target contacters: the target contacter 2 and the target contacter 3, b have a time of onset of 2020-1-20, b have a contact time with the target contacter 3 of 2020-1-18, a contact time duration of 3 minutes, a contact distance of 2 meters, b have a contact time with the target contacter 3 of 2020-1-19, a contact time duration of 4 minutes, and a contact distance of 1 meter, if the target contacters 1, 2, 3 are taken into account when determining the time duration threshold and the distance threshold, the time duration threshold is the minimum of (5,3,4), i.e. 3, and the distance threshold is the minimum of (2.5,2, 1), i.e. 1. If only target contacter 3 is considered among target contacters 2 and 3, then the duration threshold is the minimum of (5,4), i.e. 4, and the distance threshold is the minimum of (2.5,1), i.e. 1.
It should be noted that the duration threshold and the distance threshold may also be continuously updated as the acquired contact history data increases, so that the duration threshold and the distance threshold are more accurate.
According to the epidemic situation prevention and control method provided by the embodiment of the invention, the minimum value of the contact time of the patient and the target contact person is used as the time threshold, and the minimum value of the contact distance of the patient and the target contact person is used as the distance threshold, so that a lower alarm sending threshold can be adopted when the epidemic situation is serious, the prompt of user precaution is increased, and the user precaution consciousness is improved.
In this embodiment, in order to further understand the latent period of the epidemic situation related virus according to the contact history data, on the basis of fig. 3, another epidemic situation prevention and control method is provided in the embodiment of the present invention, please refer to fig. 5, and fig. 5 shows a flowchart of another epidemic situation prevention and control method provided in the embodiment of the present invention, which further includes step S105.
Step S105, calculating the latency period according to the attack time of each patient and the contact time of the patient contacting the corresponding target contact person.
In this embodiment, the latency period is the period of time from when the pathogenic stimulus invades or acts on the body to when the body reacts or begins to present symptoms.
In this embodiment, the latency may be a duration interval, i.e. the longest duration and the shortest duration, and as an implementation, the method for calculating the latency may be:
and taking the maximum value of the time difference between the attack time of the patient and the contact time of the target contact person corresponding to the contact of the patient as the upper limit value of the latency period, and taking the minimum value of the time difference between the attack time of the patient and the contact time of the target contact person corresponding to the contact of the patient as the lower limit value of the latency period to obtain the latency period.
It should be noted that the incubation period may also be determined according to an average value and a preset range of a time difference between the onset time of the patient and the contact time of the target contact person corresponding to the contact of the patient, that is, the upper limit value and the lower limit value of the incubation period are finally obtained based on the upper preset value and the lower preset value floating on the basis of the average value.
It should be noted that fig. 5 may also be used in combination with the steps in fig. 4 or fig. 3.
The epidemic prevention and control method provided by the embodiment of the invention is beneficial to effectively recognizing the propagation characteristics and infection characteristics of the virus by calculating the latency, and provides more information and data support for epidemic prevention and control.
In this embodiment, in order to predict the infection probability of a contactee who contacts a patient and has not yet been diagnosed, an epidemic prevention and control method is further provided in this embodiment, please refer to fig. 6, where fig. 6 shows a flowchart of another epidemic prevention and control method provided in this embodiment of the present invention, and the method further includes the following steps.
In step S201, contact history data of a non-patient is acquired.
In this embodiment, in order to obtain an infection prediction model for calculating an infection rate, not only contact history data of a patient but also contact history data of a non-patient are required, and the contact history data of the patient and the contact history data of the non-patient are combined and analyzed to obtain the infection prediction model.
Step S202, regression analysis is performed on the contact history data of all patients and the contact history data of non-patients to obtain an infection prediction model, so that infection prediction is performed on the contacted patients who have contacted the patients and have not yet been diagnosed by using the infection prediction model.
In this embodiment, after obtaining a large amount of contact history data of patients and non-patients, the contact duration and the contact distance in the contact history data are used as independent variables, whether infection is caused is used as a dependent variable, a statistical method is adopted to perform regression analysis on the contact history data of all the patients and the contact history data of the non-patients, and finally an infection prediction model capable of representing the relationship between the contact duration and the contact distance and the result of whether infection is caused is obtained.
According to the epidemic prevention and control method provided by the embodiment of the invention, the infection prediction model is obtained by regression analysis of the contact history data, and reference can be provided for initial medical decision making of a contacter or medical staff.
Fig. 6 may also be used in conjunction with the steps of fig. 5 or fig. 4 or fig. 3.
In this embodiment, an implementation manner of determining an infection source of a patient is further provided in an embodiment of the present invention, referring to fig. 7, fig. 7 shows a flowchart of another epidemic prevention and control method provided in an embodiment of the present invention, where the method includes the following steps:
in step S301, if the target contact person exists in the patient, the target contact person is used as the infection source of the patient.
In this embodiment, the infection source of the patient is the contacter who has a high probability of transmitting the virus to the patient, and since the contact time between the patient and the target contacter is earlier than the onset time of the patient and the target contacter has already been diagnosed, the target contacter of the patient is used as the infection source of the patient.
Step S302, if the patient does not have the target contact person, the infection source of the patient is determined according to the contact person of the patient.
In this embodiment, if the patient does not have the target contacter, it can be determined that the contacter of the patient has not appeared and has not yet confirmed a diagnosis, and at this time, the previous layer contacters contacting the contacters are sequentially searched until the target contacter of the current layer is found, and the target contacter of the current layer is taken as the target contacter of the patient.
As a specific embodiment, the method for determining the infection source of the patient according to the contacter of the patient may be:
first, a contact person of a patient is regarded as a first contact person and contact history data of the first contact person is acquired.
In this embodiment, the initial setting of the first contacter is all the contacters of the patient, and when there are a plurality of contacters in the patient, there are a plurality of corresponding first contacters.
Secondly, searching a target contactor of the first contactor according to the disease onset time of the patient and the contact history data of the first contactor, wherein the target contactor of the first contactor is a contactor of which the contact time is earlier than the disease onset time of the patient and is diagnosed in the first contactor.
Third, if the target contacter exists in the first contacter, the target contacter of the first contacter is used as the infection source of the patient.
In this embodiment, when there are a plurality of target contacts of the first contact, the plurality of target contacts may be all used as the infection sources of the patient, that is, the plurality of infection sources of the patient may be further confirmed among the plurality of target contacts, and the target contact most likely to be infected to the patient may be found as the infection source of the patient, for example, the contact with the longest contact time and the contact with the shortest contact distance of the plurality of target contacts may be used as the infection source of the patient. For example, patient a has three contacters: the contact person b, the contact person c and the contact persons d, b, c and d do not satisfy the condition of the target contact person, so that the target contact person does not exist in the step a, and at the moment, the contact persons b, c and d are obtained, and the first contact person is a collection of the contact persons b, c and d. If a contact person e satisfying the target contact person condition exists in the first contact person, then e is the source of infection of the patient a.
And finally, if the target contacter does not exist in the first contacter, taking the contacter of the first contacter as the current first contacter, continuously searching the target contacter of the current first contacter until the target contacter of the current first contacter is found, and taking the target contacter of the current first contacter as the infection source of the patient.
