How does it delineate and downgrade in Lanzhou Central high -risk zone in Lanzhou?Expert answers here

With the changes in the epidemic, the number of medium and high -risk areas designated by Lanzhou City, Gansu Province has increased significantly, causing widespread attention. At the press conference of the Lanzhou New Crown Pneumonia Epidemium (Eighth), which was held today (July 15), Shi Langan, deputy director of the Lanzhou Disease Prevention and Control Center, introduced. As of 10:00 on July 15th, at 10:00 on July 15th, There are 47 high -risk areas and 42 mid -risk areas in Lanzhou.

In order to do a good job in the prevention and control of the new coronary pneumonia epidemic, according to the requirements of the "New Coronatte Pneumonia Pneumonia Prevention and Control Plan (Ninth Edition)", Lanzhou City will specify the standards and prevention and control measures in the risk area. The concept of medium and low -risk areas has formed a new risk zone delineation and control solution to scientifically accurate, quickly and efficiently control the spread of the epidemic.

At the same time, Lanzhou City has established a reporting mechanism for division of risk areas. The city and district -level epidemic analysis and research and judgment expert group shall, based on the activity trajectory and risk of epidemic dissemination according to the confirmed cases and asymptomatic infected infected people. Basic information such as confinement, ventilation, crowd protection, and personnel agglomeration, comprehensive evaluation and judgment, accurate scientific scientific regulations on high, medium, and low -risk areas, and were released to the public by the Lanzhou Lanzhou City Defense and Control Office.

Specific delineation standards and downgrade standards are as follows:

High -risk zone refers to the residence of cases and asymptomatic infected people, as well as workplaces and regions with frequent activity and high risk of epidemic dissemination. In principle, the high -risk zone is determined by the residential communities or villages, and the scope of risk areas can be made according to the results of epidemiological surveys. The high -risk zone adopts the control measures of "not leaving home and on -site services".

High -risk zones can be reduced to medium -risk zone for 7 consecutive days, and those who have no new infections for 3 days in a row can be reduced to low -risk zones. For high -risk areas of high -risk areas, 7 -day centralized isolation medical observation is adopted. Each nucleic acid detection is carried out at the first, 2, 3, 5, and 7 days of concentrated isolation.

The mid -risk zone refers to the residence of cases and asymptomatic infections, for a certain period of activity, and may have a working place and area of ​​the risk of epidemic dissemination. The central risk zone adopts the management and control measures of "people who do not get out of the area and peaks".

The mid -risk zone has no new infection for 7 consecutive days and can be reduced to a low risk zone. For personnel who overflows cross -region overflowing, we will take 7 Heavenly House Medical Observation. During the observation of home medical observations, nucleic acid testing is performed on each 1, 4th, and 7th days. If you do not have the conditions for home isolation, we will take centralized isolation medical observations.

Other areas (districts) where the mid -to -high risk zone is located is defined as a low -risk zone. The low -risk zone takes the prevention measures of "personal protection and avoiding gathering". Low -risk areas to leave their areas or cities in their areas should hold a 48 -hour nucleic acid test negative certificate.

According to the "New Coronatte Pneumonic Pneumonia Prevention and Control Plan (9th Edition)", during the treatment of the epidemic disposal, if individual cases and asymptomatic infections are low in residence, workplace, and activity area After being judged that there is no risk of community communication, there is no risk area.
