What is the difference between Guangzhou to divide high and middle -low risk areas?Disease Control expert interpretation

Recently, after the release of the "New Coronatte Pneumonic Pneumonia Prevention Plan (Ninth Edition)" (hereinafter referred to as the "Ninth Edition Plan"), it was first divided into high, middle and low risk zones in the epidemic. How to terminate the mid -to -high risk zone? Focusing on hot topics, Qin Pengzhe, deputy director of the Guangzhou Centers for Disease Control and Prevention, answered.

Controlled area, control zone, prevention area, why is it a high, medium, and low -risk zone this time?

Qin Pengzhe: According to the requirements of the ninth edition plan, Guangzhou adheres to the principles of "prevention of prevention, combining control, scientific science according to law, and classification". Municipal, district, flag) is accurately divided into three types of risk areas: high -risk zone, mid -risk zone, and low -risk zone. According to the new plan, you can simply understand the high -risk zone as the original seal control area, and adopt seal control measures such as "not leaving home and on -site services"; Regional control measures such as districts and peaks "; low -risk areas are equivalent to the original prevention zone, adopting preventive measures such as" personal protection and avoiding gathering ". Low -risk zone personnel who leave the city should hold a 48 -hour nucleic acid test negative certificate.

Why no longer divide the control zone, control zone, and prevention area?

Qin Pengzhe: In the past, the three types of risk areas of high, middle and low, were different from the definition of three types of regions: seal -controlled areas, control areas, and prevention areas. They could be confused in actual work, and the citizens were not easy to understand. According to the ninth edition plan, the management of the three districts in the current stage has achieved "the combination of shape and spirit", which is more conducive to the prevention and control of epidemic conditions.

Do you need to divide the risk zone as long as you have infection?

Qin Pengzhe: The ninth version of the plan is clear. During the treatment of the epidemic, those such as individual cases and asymptomatic infections have low risk of spreading the residence, working place, and activity area. , No risk zone. In actual work, we are committed to achieving accurate prevention and control and minimizing the impact of the normal production and life.

Does the low -risk zone at this stage mean that the meaning is completely different from the low -risk zone that everyone understands in the past?

Qin Pengzhe: In the past, except for the high -risk zone, the whole country was a low -risk zone, and it used normal prevention and control measures. According to the ninth edition plan, the current low -risk zone is established in response to the high -risk zone. It is equivalent to the original defense zone. It is necessary to implement "personal protection and avoid gathering." Taking Guangzhou as an example, although there is a local epidemic, most areas still belong to the area where there is no need to define the risk areas.

How to terminate the risk zone?

Qin Pengzhe: According to the ninth edition plan, the mid -risk zone has no new infection for 7 consecutive days, and all personnel in the risk area on the 7th day of the risk area are negative, and can be reduced to low risk areas. The requirements of the high risk zone are stricter. Those who have no new infections for 7 consecutive days, and all personnel in the risk area on the 7th day of the risk area are negative, which can be reduced to medium -risk zone; Those who increase infection can be reduced to low -risk areas. After all the central and high -risk areas in the county (city, district, and flag) were lifted, normalized control and control, the low -risk zone was lifted by itself.
