What are the conditions from high risk to low risk?

From the medium-risk area to the low-risk area, there are no newly confirmed local cases in the area judged as medium-risk for 14 days; In order to reduce from a high-risk area to a medium-risk area, it is required that 10 confirmed cases or 1 1 clustered epidemic situation do not occur in the area judged as high-risk for 14 consecutive days.

The incubation period of COVID-19 is usually 3 to 7 days, and the longest is 14 days. Therefore, the observation time is set at 14 days, which may be relatively safe if you are not sick. Of course, there are some cases where the incubation period of the virus exceeds 14 days. After the national large-scale test results come out, if there are few cases, it is reassuring to test the key population and high-risk areas many times, and the isolation can be lifted. Or through the national nucleic acid detection and the analysis of people in middle and high-risk areas, which places can not be healthy, those places will be isolated, and other safe places can be released from isolation.

Different risk levels have different coping strategies.

1. Low-risk areas: the strategy of implementing foreign defense investment.

We will spare no effort to restore the order of production and life, lift road traffic restrictions, and help enterprises solve problems and troubles in employment, raw materials, funds and equipment. And do not set conditions for the resumption of production, and do not delay the resumption of production under the pretext of approval and filing.

2. Medium risk area: implement the strategy of external introduction and internal defense.

Restore normal production and living order in an orderly manner as soon as possible, organize personnel to return to their posts in an orderly manner, guide employers to strictly implement disinfection, ventilation, temperature measurement and other requirements, reduce personnel density, reduce personnel gathering, strengthen personnel protection, eliminate potential risks, and realize the simultaneous promotion of epidemic prevention and control and enterprise resumption of work and production.

3. High-risk areas: implement internal non-proliferation, export prevention and strict control strategies.

We should continue to concentrate on preventing and controlling epidemics. After the epidemic situation is effectively controlled, the scope of resumption of work and production will be expanded in an orderly manner. There is a premise that high-risk areas should also ensure the normal operation of enterprises involving important national economy and people's livelihood, such as epidemic prevention and control, public utilities and people's daily necessities.
