Disease transmission prevention and control method and system

Abstract

The invention provides a disease transmission prevention and control method and system, and the method comprises the steps: taking a to-be-monitored person as a node, and collecting the basic data ofeach node and an adjacent node of the node as node data; taking the nodes with the basic data exceeding a set threshold value as initial infector nodes; constructing an infection graph network on thebasis of the vertex and other node information adjacent to the vertex by adopting an SIR model and taking an initial infected person node serves as a vertex, wherein a plurality of propagation centerstates in the infection graph network are set as infection states I, all other nodes are set as susceptibility states S, and the disease propagation process is simulated; calculating to obtain a source node by adopting a traceability algorithm; and according to the importance degree of other nodes, generating the number of nodes needing to be isolated, outputting labels of the source node and theother nodes at the same time to prevent and control disease transmission. The method is high in disease screening efficiency, disease propagation can be effectively prevented, and effective auxiliarywork is provided for subsequent diagnosis and treatment.

Description

technical field [0001] The present invention relates to the technical field of epidemic prevention and control, in particular to a method and system for preventing and controlling disease transmission. Background technique [0002] Sanitation and epidemic prevention is the health construction that our country has been insisting on since the founding of the People's Republic of my country, and has achieved great achievements, especially the control and monitoring of various infectious diseases, and gradually eliminated the development and prevalence of various infectious diseases. Sanitation and epidemic prevention in a narrow sense refers to a series of measures taken to prevent and control the spread of diseases to prevent the spread of infectious diseases. Sanitation and epidemic prevention in a broad sense refers to the sanitation and epidemic prevention work of sanitation and epidemic prevention stations, including sanitation supervision and disease control. It has grad...

AI Technical Summary

Problems solved by technology

[0007] 1. There is no data acquisition method involving the establishment of maps

[0008] 2. Even if the method explains the acquisition method, without the support of real dissemination data, the way of knowledge graph is difficult to work

[0009] 3. There are deficiencies in the function of the algorithm: there is no algorithm to point out the traceability, and it is impossible to point out the source of infection and the people who need to be isolated

[0011] 1. The adopted infection chain structure cannot accurately determine the close contacts of confirmed persons

[0012] 2. There is no algorithm to point out the traceability, and it is impossible to point out the source of infection and the people who need to be isolated

[0013] To sum up, the existing epidemic prevention and control technology cannot really meet the needs of epidemic prevention and control. At present, no description or report of similar technology to the present invention has been found, and similar information at home and abroad has not been collected yet.
