1, analyze the epidemic situation with mathematical tools.
2. Big data helps to prevent and control the epidemic. On the basis of collecting a large number of telephone data of residents, the intelligent outbound platform application launched by Baidu Company can dial out more than 500 telephones at the same time, and call out more than 5,000 telephone numbers at 1 hour, so as to realize multi-scene functions such as floating population survey, local residents survey/return visit, and specific population notification.
3. Forecast epidemic situation with mathematical model.
