Description
Technical Field
The invention relates to the technical field of information processing, in particular to a system and a method for tracking infectious disease close contact personnel.
Background
Infectious diseases are characterized in that infectious patients or suspected patients are infected and spread rapidly by contacting with others in close range. Therefore, once the epidemic situation of the infectious disease (such as new coronary pneumonia) occurs, the key point for controlling the spread of the epidemic situation is to quickly determine the close contact persons, the sub-close contact persons (if necessary: the sub-close contact persons), and the epidemic situation space-time spread chain diagram (including the trace tracks of the close contact persons) of the patients or suspected patients, and can dynamically update, automatically notify the relevant departments in the corresponding areas (such as the corresponding level of disease control center and/or emergency management department) and take necessary control measures (such as the implementation of forced centralized isolation on the close contact persons) by the departments (matched by police parties if necessary) according to the corresponding law regulations of the state, thereby realizing effective and accurate epidemic resistance and saving a large amount of social cost.
The determination and dynamic update of the patient and the epidemic situation space-time propagation chain diagram are technical problems, and the rapid tracking of close contacts and sub-close contacts which leave an epidemic situation occurrence area and the necessary measures for the close contacts and the sub-close contacts are particularly important for epidemic situation prevention and control.
At present, a large amount of manpower and material resources are input into local governments for epidemic prevention, and the work of whole-person nucleic acid detection, whole-person sealing, risk person tracking and the like is carried out. In the investigation, tracking and prevention and control of epidemiology of new coronavirus epidemic situation, manual registration (such as nucleic acid detection, entering and exiting offices, public places and residential places) is still adopted in a large quantity or part of the cases, and the defects are that writing or data are unclear, incomplete and even wrong easily, the subsequent data storage and processing burden is heavy, the information circulation and use efficiency are low, and the like. For the contact of residents who have once gone to high-risk areas, the phenomena of multi-head contact and multi-head declaration (usually, the contact is realized through a telephone or a mobile phone) occur, and the contacted residents cannot clearly contact the real identities of the residents, so that potential safety hazards and risks exist. The information of multi-head contact and multi-head declaration is often manual (readability is difficult to guarantee and error is easy), manual arrangement is also needed, and the information is further reported layer by layer through different government sub-management channels, so that the accuracy, integrity and consistency cannot be guaranteed.
In addition, it is difficult to quickly track and take necessary measures for closely contacting persons and persons who have left the epidemic situation occurrence area by current epidemic prevention means. Therefore, it is necessary to develop a tracking system and method for close contact persons of infectious diseases, so as to quickly determine the close contact person, the sub-close contact person (if necessary: the sub-close contact person), and their epidemic situation space-time propagation chain diagram of the confirmed or suspected confirmed person, and dynamically update, automatically notify the relevant departments (such as the corresponding level of the centers for disease control and/or the emergency management department) in the corresponding areas, and take necessary control measures (such as performing forced centralized isolation on the close contact person) by these departments (if necessary, by police) according to the corresponding laws and regulations of the country, so as to achieve effective and accurate epidemic prevention and save a lot of social costs.
