How to define the medium risk area?

/kloc-There are new confirmed cases within 0/4 days, and the cumulative confirmed cases are no more than 50.

The specific risk delineation criteria are: taking counties and urban areas as units, and no confirmed cases or newly confirmed cases for 14 consecutive days are low-risk areas. /kloc-There are new confirmed cases within 0/4 days, with no more than 50 confirmed cases or more than 50 confirmed cases. /kloc-no clustering epidemic occurred within 0/4 days, which is a medium risk area, with more than 50 confirmed cases, and a clustering epidemic occurred within 0/4 days, which is a high risk area.

Among them, Beijing is considered according to three dimensions: one is the region, with streets and towns as the basic units. Followed by time, the longest incubation period is 14 days. The last one is the epidemic, how many cases there are, and whether there is a cluster epidemic.

Precautions:

Implementing the strategy of external defense and internal non-proliferation in the middle-risk area: on the basis of taking various measures in the low-risk area, we should make good preparations for medical treatment, personnel, materials and places related to disease prevention and control, and conduct isolated medical observation and management for close contacts of cases.

Taking school classes, construction units, factory workshops and workplace offices as the smallest units, and taking case discovery, epidemiological investigation and epidemic analysis as clues, reasonably determine the prevention and control management places and personnel, and implement targeted prevention and control measures. Townships, streets and urban and rural communities without confirmed cases can take prevention and control measures with reference to low-risk areas.
