The invention relates to the technical field of infectious
disease prediction, in particular to an
infectious disease transmission risk prediction method and
system based on
big data analysis, and the method comprises the steps: firstly collecting multi-source heterogeneous data of
population flow, environmental
meteorology, historical epidemic situation,
social media and
public health resources, and then carrying out the cleaning, fusion and space-
time alignment of the data, constructing a standardized
database, training a dynamic propagation model based on
machine learning, iteratively optimizing parameters by combining an SEIR improved model and real-
time data, and finally outputting a regional
risk level prediction result and a visual early warning map; according to the method, the multi-source heterogeneous data are fused, and the dynamic
machine learning model is used for real-time analysis, so that complex influence factors of
virus transmission can be more comprehensively captured, prediction deviation caused by single data or update
delay in a traditional method is remarkably reduced, the risk early warning precision is improved, and the risk early warning efficiency is improved. And minute-
level data processing and
risk level updating are realized.
