Normalization prevention and control area is not a low-risk area, and they are not the same concept. Low-risk areas are other areas in counties (cities, districts, banners) where middle-high risk areas are located. Only when the county (city, district, banner) has no medium-high risk area can the low-risk area be adjusted to normal prevention and control, and it can be called normal prevention and control area. In low-risk areas, strengthen social control, implement "personal protection, avoid aggregation" and leave the city with a 48-hour negative nucleic acid test certificate.
The normalized prevention and control area is the whole county (city, district, banner) after all the high-risk areas are lifted. Normalization of prevention and control includes ten normalization, namely, normalization of health protection, normalization of temperature measurement and code checking, normalization of foreign personnel investigation, normalization of fever screening, normalization of key population detection, normalization of monitoring and early warning, normalization of precise disposal, normalization of disinfection and sterilization, normalization of environmental remediation and normalization of prevention and control preparation.
