System for tracing infection source based on epidemic infectious disease virus field

Abstract

The invention discloses a system for tracing an infection source based on an epidemic infectious disease virus field. The system comprises an infectious disease spreading city diffusion modeling unitwith takes air as a medium, a collecting, cleaning and processing unit for collecting, cleaning and processing spatio-temporal trajectory data and infection attack data of virus carrying crowds, a virus carrier position semantic information acquisition unit, a virus distribution density calculation unit which takes the virus carrier as a position center, a virus carrying population time, space andvirus distribution density data mapping unit, a temporal GIS-based epidemic infectious disease virus field cloud platform construction unit, a calculation unit for calculating the probability that the virus carrier is infected by a virus somewhere at a certain time, a calculation unit for calculating the probability that the virus carrier is infected by the virus within a certain tracing time period, a screening unit for screening the infected time period and a virus field of the virus carrier, and an association unit for associating the infected virus carrier with the virus carrier generating the virus field, wherein the units above are connected in sequence. The system can trace the virus infection source and the propagation chains, so that virus propagation is quickly restrained.

Description

technical field [0001] The invention relates to the application of mobile phone positioning, temporal GIS, big data and cloud computing in the field of prevention and control of epidemic infectious diseases, in particular to a system for tracing the source of infection based on the virus field of epidemic infectious diseases. Background technique [0002] The core of an infectious disease outbreak lies in its contagiousness, which can be transmitted directly or indirectly from one person to another or more people. To deal with such sudden outbreaks of infectious diseases, humans have mastered a very old but extremely effective method-that is, isolation. [0003] There are three cores of isolation: [0004] The first is to find and manage the source of infection. Scientists have confirmed that the new coronavirus is the pathogen of this infectious disease outbreak, and it can spread from person to person, so the rapid identification and isolation of those who are already ...

AI Technical Summary

Problems solved by technology

[0015] In order to overcome the existing infectious disease prevention and control methods, it takes a lot of manpower to trace the source of the virus and find out the route of infection, it takes a long time, the results are inaccurate, the investigation takes a long time, and it takes a lot of energy and time for infectious disease experts, static investigation results It is difficult to trace the infection route from the time and space dimensions, from the global and local, and dynamically. The present invention provides a virus distribution density map with the virus carrier as the center of the position through processing the spatiotemporal trajectory data of the virus carrier population and the infection incidence data. , and then trace back when and where the virus carriers were infected by the virus based on the virus distribution density map of the temporal GIS, and finally obtain the system of the transmission chain of all infected virus carriers and the virus carriers that generated the virus field
