Generally speaking, the criteria for dividing high, medium and low risk areas are whether there are confirmed cases in COVID-19 and how many confirmed cases in COVID-19 in a street or community within 14 days. At the same time, the specific criteria for dividing high-,medium-and low-risk areas need to be adjusted in time according to the changes of the epidemic situation in COVID-19.
Even in low-risk areas, hospitals, schools and other crowded places are the focus of prevention and control. Therefore, the new version of the plan highlights the classification guidance, refines the prevention and control measures for key places, institutions and people, and guides special institutions such as pension institutions and welfare institutions for the disabled to implement prevention and control measures after enterprises resume work, schools and kindergartens resume classes, and enter the park.
