Document Type and Number:
WIPO Patent Application WO/2021/189516
Kind Code:
A1
Abstract:
A method and a system for simulating the process of temporal and spatial circulation of influenza with massive trajectory data. Said method comprises: synthesizing an urban population on the basis of population census data and building census data, and assigning a corresponding population attribute to an individual of the synthesized urban population (S1); for the individual of the synthesized urban population to which the population attribute has been assigned, constructing an individual activity chain mainly consisting of mobile phone position data and being assisted by travel investigation data (S2); on the basis of the constructed individual activity chain, dynamically constructing, with one hour as a time step, a contact network of 24 time series in a day (S3); according to the constructed contact network, using an SEIR model to simulate the circulation of an influenza at a high temporal and spatial resolution (S4); and analyzing a simulation result from two perspectives of time and space, so as to analyze a high-risk area during circulation of the influenza and accurately position a key spatial position during circulation of influenza epidemic situation (S5). Said method can invert the temporal and spatial information of influenza outbreaks on different temporal and spatial scales, effectively solving the problem of being unable to realize real location of the spatial position of an infected person and a potentially high-risk circulation area.
