Early-warning and tracing method for unknown infectious diseases

Abstract

The invention discloses an early-warning and tracing method for unknown infectious diseases. The method comprises the following steps: S1, establishing an early-warning and tracing system for unknowninfectious diseases; S2, collecting doctor-seeing information and positional information of patients, and uploading the doctor-seeing information and the positional information to a database; S3, allowing the database to classify the treatment information of all the patients according to different symptoms; S4, enabling an unknown infectious disease early-warning module to analyze the distributionrule of patients with certain symptoms in the database and to give out an early-warning signal when the density of the patients is high; S5, allowing an unknown infectious disease early-warning and decision-making module to trace back infectious disease patients and possibly infected people; and S6, fitting the occurrence position of a last-generation maximum possible infection source, and carrying out continuous iteration until the a primary-generation maximum possible infection source is traced back. According to the early-warning and tracing method for unknown infectious diseases, early warning can be given out before confirmation of unknown infectious disease, and patients with the infectious diseases and people who may be infected with the infectious diseases can be reversely tracedback after the confirmation of the unknown infectious diseases.

Description

technical field [0001] The invention relates to the technical field of public health, in particular to a method for early warning and tracing of unknown infectious diseases. Background technique [0002] With the advancement of urbanization and the rapid development of transportation in China, the population density in urban areas is relatively high, and the population flow rate is relatively fast. If an infectious disease occurs, it will lead to a rapid mass epidemic, and it is difficult to attract enough attention before the epidemic reaches a certain severity. . And after attracting a certain amount of attention, it is also difficult to confirm the source of infection and patient zero. [0003] At present, most of the existing early warnings of infectious diseases cannot be retrospectively traced, and their functions are relatively single. The application number is 201710315294.0, and the main function is to monitor known infectious diseases. The movement of relevant pe...

And after attracting a certain amount of attention, it is also difficult to confirm the source of infection and patient zero

[0003] At present, most of the existing early warnings of infectious diseases cannot be retrospectively traced, and their functions are relatively single. The application number is 201710315294.0, and the main function is to monitor known infectious diseases. The movement of relevant personnel in high-risk areas, and early warning of infection for those who may be infected, mainly for people with known infectious diseases, who are located in unknown infectious diseases, and cannot make timely early warnings; the application number is 201910099513.5, and the name In the invention patent application document for the infectious disease monitoring system, the server takes the leave information and registration information sent by the student terminal as the leave record, and saves the leave record and the morning and afternoon checkup record sent by the teacher terminal as the health record in the database; Assuming that the number of health records with the first infectious disease in the area exceeds the preset early warning threshold, the early warning information corresponding to the first infectious disease in the preset area is generated, which is mainly aimed at fixed groups of people and requires special sampling. It consumes a lot of manpower and material resources; the application number is 201910046912.5, and the name is the invention patent application document of the infectious disease early warning method based on smart contract and the infectious disease data blockchain system, and the data is sent to each of the multiple consensus nodes. Determine the authenticity of the data separately and reach a consensus. When collecting the data, the blockchain method is used, and the data collection is not comprehensive enough; the application number is 201711375439.2, and the name is a patent for a method of early warning of infectious diseases The application documents belong to the field of big data analysis technology. First, establish a database of information on the incidence of infectious diseases, and set a baseline window to perform weight preprocessing on the incidence of infectious diseases. This is only a data processing method and cannot be used for unknown infectious diseases. Early warning and traceability
