Prevention and control method and prevention and control system of disease control and travel information interconnection

Abstract

The invention relates to the public health technology field and discloses the prevention and control method of disease control and travel information interconnection. The method comprises the following steps of retrieving the historical data of local infected cases and the composition of environmental factors affecting the survival of a disease infection source, and fitting a grid risk map; determining a newly infected person as an infection source, and obtaining the travel information of the newly infected person in the period of time before attack; classifying and screening the travel information, excavating possible resident points, combining with spatial road network data and carrying out semantization on the possible resident points; comparing the possible resident points in step 3 with the risk map generated in step 1 to acquire a main suspicious point which is taken as a high probability occurrence point; adopting an association rule excavation algorithm or a string pattern excavation algorithm to excavate a motion pattern so as to predict a possible propagation trend; and according to the above result, intervening a high risk area. The trend of an infectious disease is predicted and prevention and control cost is reduced.

Description

technical field [0001] This application relates to the technical field of public health, in particular to a prevention and control method and system for disease control and travel information interconnection. Background technique [0002] At present, the main emergency measures for infectious diseases focus on the control of the sick and the isolation of high-risk groups, etc. However, due to the latent characteristics and transmission methods of some diseases, the early control of infectious diseases also adopts a comprehensive net. Strict control of defense, no focus, and the process is complicated and takes a long time. [0003] Patent document CN201610060508X in the current technology provides a method for tracking the source of infection and predicting the epidemic trend of infectious diseases by using mobile phone tracks. It extracts the mobile phone traffic data of the infected person, as well as the relevant base station location area identification code and the bas...

AI Technical Summary

Problems solved by technology

However, when using base station information for trajectory analysis, due to the large range of the base station, it is impossible to accurately locate the base station, and there is a vibration problem in the base station connection, and the base station identification cannot be accurately identified. In addition, there are overlaps between the base stations, and the user's location data cannot be continuously recorded

As a result, deviations will be caused in the subsequent analysis process, and the accuracy of the prediction results needs to be optimized
