In step S206, a first weight of the at-risk patient is determined according to the successfully matched symptom set of the at-risk patient.
In the embodiment of the present disclosure, different symptom sets may correspond to different weight values. For example, the weight value for symptom set "fever" may be, for example, 0.7, the weight value for symptom "cough" may be, for example, 0.6, and the weight value for symptom set "fever, cough" may be, for example, 1.2. Wherein the weight value of the successfully matched symptom set of the at-risk patient may be determined as the first weight of the at-risk patient.

In the embodiment of the disclosure, the difference operation may be performed on the trajectory time information and the symptom time information of the risk patient, and the nonlinear operation or linear operation may be performed on the difference operation result of the trajectory time information and the symptom time information, so as to determine the second weight corresponding to each trajectory address information of the risk patient. For example, if a patient a at risk stays at X, Y, and Z for the first day, the symptom time information of the patient a at risk stays at Z for the second day, it can be determined that the patient at risk has a second weight of 0 with the target area X, 0.3 with the target area Y, and 0.8 with the target area Z.
In step S210, a risk factor of the risk patient corresponding to the target area is determined according to the first weight and the second weight.
In an embodiment of the present disclosure, a sum of the first weight and the second weight may be determined as a risk factor for the at-risk patient corresponding to the target area.
In step S212, a total risk value of the target area in each preset period in the preset duration is determined according to risk factors of the target area and patients at risk in each preset period in the preset duration.
In the embodiment of the present disclosure, the risk factors corresponding to the target area and the risk patients existing in the target area in each preset period within the preset duration may be summed to obtain the total risk value of the target area in each preset period within the preset duration.

And determining a second weight corresponding to the risk patient and each track address information according to the track time information and the symptom time information, and comparing the time of the risk patient producing symptoms with the stay time on each track address information to accurately reflect the risk contribution rate of the event of the risk patient producing symptoms to each track address information. And determining the corresponding target weight of each target region in each preset period within a preset time length according to the first weight and the second weight, and accurately determining the target weight of each target region according to the symptom severity and the symptom occurrence time of the risk patients so as to accurately reflect the risk degree of each target region.

In step S306, the risk index of the target area in the preset duration is determined according to the risk sub-index corresponding to each preset period in the preset duration and the number of periods.
In an exemplary embodiment, when the risk sub-index is n and the number of cycles is l, the risk index of the target area may be determined according to a sum or a weighted sum of the risk sub-index and the number of cycles.
