Why is there no high risk in Shanghai?

According to the definition standard of high-risk area, it can be identified as high-risk area if two conditions are met. First, there are more than 50 confirmed cases in the administrative area, and second, there is a cluster epidemic within 14 days. At present, the epidemic situation in Shanghai seems to meet this standard, but the reality is not included in the high-risk area.

Although there are many new cases in Shanghai every day, they are mainly asymptomatic infected people. According to the relevant national regulations, the areas involved by asymptomatic infected people do not need to be designated as the high-risk areas of the epidemic, and these patients only need to conduct centralized isolation observation.

In addition, these new cases were found in closed-loop management and are still under control. Some experts explained that at present, Shanghai is still under the static management of all staff, and repeated nucleic acid screening is being carried out, and the list of high-risk areas has not been updated.
