What does the history of living in high-risk areas mean?

It is a self-declaration of where you are going, indicating where you and your family have been, so that the relevant institutions can judge whether this person is likely to be infected, because if you have been in a high-risk area, there is a certain possibility of being infected.

According to the relevant requirements of the joint prevention and control mechanism in the State Council, on July 28th, 2020, Beijing formulated the "COVID-19 epidemic risk grading standard in Beijing", which clearly took the clustered epidemic situation and the number of new cases in the community (village) 14 days within my municipal area as the risk grading index.

Among them, within 14 days, 2 or more local clustering epidemics or 5 or more local confirmed cases were added, which was a high incidence area; Within 14 days, there were 2-5 new local confirmed cases or new local clustered epidemics 1, which is a medium-risk area; 14 days, there was no new local clustering epidemic, which was a low-risk area.
