Abstract

One or more embodiments of the invention provide a virus propagation risk early warning method, device and equipment based on graph calculation, and the method comprises the steps: obtaining contact data among all users, and constructing a contact flow graph based on the contact data; determining a positive patient in the contact flow graph, and determining a contact person of the positive patient, wherein the contactors comprise direct contactors of positive patients and indirect contactors of the positive patients, and risk levels are distributed to the direct contact person and the indirectcontact person respectively; and respectively carrying out risk level elimination judgment on the direct contact person and the indirect contact person. By constructing the contact flow graph, the positive patient and the contact person thereof can be quickly determined, the risk level of the contact person can be allocated, and the risk level of the contact person can be updated and eliminated in time based on the contact flow graph, so that the timeliness and high efficiency of propagation risk early warning are effectively improved.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of risk early warning, and in particular to a method, device and equipment for early warning of virus transmission risk based on graph calculation. Background technique [0002] How to obtain accurate and timely information on the spread of the epidemic has become increasingly important. Contact tracing of people infected with the coronavirus could help ease social distancing restrictions, public health experts say. Due to the popularity of smart devices, some software (such as TWS and TraceTogether) have been designed to collect real-time contact data between people, and based on the collected data, potential people who may be infected with COVID-19 can be found. [0003] From the perspective of data management, most contact data are processed using relational databases at this stage, but using relational databases to search contact data cannot be efficiently searched and lac...
