The number of confirmed cases decreased, and there was no cluster epidemic within 14 days. People's governments at the provincial level carried out dynamic analysis and judgment according to the requirements of relevant laws and regulations, and promptly lowered the emergency response level or terminated the emergency response by region after the number of cases kept steadily decreasing and the risk of epidemic spread was effectively controlled.

according to the risk classification standard in the joint prevention and control mechanism of the State Council against pneumonia in novel coronavirus "Guiding Opinions on Scientific Prevention and Control, Precise Policy, Zoning and Grading to Do a Good Job in COVID-19 Epidemic Prevention and Control", the specific risk classification standard is:

1. Counties and urban areas are taken as units, and there are no confirmed cases or no newly confirmed cases for four consecutive days as low-risk areas.

there are newly confirmed cases within 2 and 14 days, and the cumulative number of confirmed cases is not more than 51, or the cumulative number of confirmed cases is more than 51, and no cluster epidemic has occurred within 14 days, which is a medium-risk area.

3. There are more than 51 confirmed cases, and a cluster epidemic occurred in a high-risk area within 14 days.

Extended information:

Prevention and control measures of different risk levels:

1. Low-risk areas

Implement the strategy of importing external defense, comprehensively restore the production and living order, cancel road traffic restrictions, help enterprises solve problems and problems in employment, raw materials, capital and equipment, and do not set conditions for enterprises to resume production, and do not delay enterprises' resumption of work on the pretext of approval and filing.

2. In medium-risk areas,

implement the strategy of external import prevention and internal proliferation prevention, restore normal production and living order in an orderly manner as soon as possible, organize employees 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, and eliminate potential risks, so as to achieve simultaneous progress of epidemic prevention and control and enterprises' resumption of work and production.

3. In high-risk areas

, the strategy of internal non-proliferation, external export prevention and strict management and control shall be implemented. We should continue to concentrate on epidemic prevention and control. 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 epidemic prevention and control, public undertakings, people's daily necessities and other enterprises involving important national economy and people's livelihood.
