Problems solved by technology

[0004] However, in the existing prevention and control of infectious diseases, the influence of recessive infection on the prevention and control of infectious diseases is ignored and the existing framework is lacking to model the influence of recessive infection, resulting in the inability to accurately implement interventions for the prevention and control of infectious diseases

Embodiment Construction

[0060] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0061] At present, the methods of individual infectious disease prevention and control are mainly based on graphs, based on infectious disease prediction, based on heuristic algorithms, and based on reinforcement learning. Graph-based methods often treat individuals as nodes, and the edges between individuals represent the contact and connection between individuals. Through the relevant topol...

Abstract

The invention provides an individual movement intervention infectious disease prevention and control method and system. The method comprises the following steps: acquiring daily historical state information and individual relationship information of individual users in a target city within a preset time interval; and inputting the historical state information and the individual relationship information into a trained individual movement intervention infectious disease prevention and control model to obtain prevention and control intervention measures of each user individual in the target city, wherein the trained individual movement intervention infectious disease prevention and control model is obtained by training a graph neural network, a long and short term neural network and an intelligent agent according to sample user individual state information and sample individual relationship information, and the intelligent agent is constructed based on a partial observable Markov decision process; and the individual state information of the sample user comprises health state information of a hidden infected person converted into a dominant infected person. According to the invention, the number of infected people can be reduced as much as possible under low travel intervention.

Description

technical field [0001] The invention relates to the technical field of prevention and control of individual infectious diseases, in particular to a method and system for individual mobile intervention in the prevention and control of infectious diseases. Background technique [0002] Individual Mobility Intervention Epidemic Control (Individual Mobility Intervention Epidemic Control) refers to carrying out travel intervention measures of different strengths for some high-risk close contact groups through the historical trajectory of the individual and combined with the characteristics of the individual, so as to achieve the effect of infectious disease prevention and control . However, in the actual prevention and control of infectious diseases, since latent infections in the incubation period cannot be found through non-drug methods, and these latent infections are often highly infectious, it is very easy to cause infectious diseases to get out of control And the sharp ris...
