Abstract

The embodiment of the invention provides an infectious disease propagation evaluation method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring target trajectory data corresponding to an evaluation object in a preset area in a first time slice, wherein the preset area comprises a plurality of sub-areas; determining a matching subarea matched with each evaluation object in the first time slice based on the target trajectory data, wherein the matching subarea is one of the plurality of subareas; taking at least one of the plurality of sub-regions as a target sub-region, and evaluating an evaluation object in the target sub-region based on the infectious disease model so as to determine a propagation trend of the evaluation object of the infectious disease in the preset region in the first time slice; and taking the next time slice as the first time slice, and executing the above steps again until the target time period is ended, so asto determine the propagation trend of the infectious disease in the evaluation object in the preset area in the target time period. The effect of evaluating the infection trend of each region in a fine-grained manner is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of intelligent prediction, and in particular, to an evaluation method, device, computer equipment and storage medium for the spread of infectious diseases. Background technique [0002] Trajectory simulation evaluation plays an important role in disease prevention and control. [0003] At present, the commonly used method of evaluating transmission is based on the simulation model of infectious diseases. Most of them use mathematical models (which can be divided into ordinary differential equations, partial differential equations, and network dynamics models) to analyze the population of the region and analyze the regional disease. Development process and assessment of changing trends. [0004] However, these models focus on simulating and estimating the overall number of patients, without considering the real transmission process of the infection, and cannot fine-grainedly assess the ...
