High -risk zones can be reduced to mid -risk zone for 7 consecutive days without new infections.

As of 10:00 on July 15th, a total of 47 high -risk areas and 42 central risk areas in our city. With the changes in the epidemic, the number of medium and high -risk areas defined by our city has increased significantly, causing widespread attention. At the press conference of the Lanzhou New Crown Pneumonia Epidemic Epidemium on July 15th, Shi Langan, deputy director of the Municipal Centers for Disease Control and Prevention, to set up the standards for these risk areas, when will it be lifted? Responded.

Shi Langan said that for science and precision the prevention and control of new coronary pneumonia, in accordance with the "New Coronatte Pneumonia Pneumonia Prevention and Control Plan (9th Edition)", the standards and prevention measures of risk areas are determined The concepts of high, medium, and low risk areas have formed a new risk zone delineation and management and control solutions in order to scientifically accurate, quickly and efficiently control the spread and spillover of the epidemic.

The city's establishment of a reporting mechanism for the 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 will be released to the public by the Municipal Federation of Control and Control.

For the division standards and lifting conditions of the risk zone that the public cares about, the historical danger is explained that the high -risk zone refers to the residence of cases and asymptomatic infections, as well as the workplace and place of activities with frequent activity and high risk of epidemic transmission. Waiting for areas. 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. High -risk areas adopt management measures for "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.
