Today (June 28) in the afternoon, a press conference was held in Beijing on the prevention and control of the coronavirus epidemic. The conference announced the characteristics of the new plan for the prevention and control of the epidemic of coronavirus (ninth edition). Major changes from the eighth edition of the old plan include:
1. Optimize and adjust the isolation management period during the quarantine period and the risk management method
Reduced the time for quarantine isolation and control for close contacts and incoming personnel from "14 days of centralized medical supervision in isolation + 7 days of medical supervision at home" to "7 days of centralized medical supervision in isolation + 3 days of medical supervision at home".
The testing activities have been changed from “centralized isolation medical observation”, nucleic acid testing on the 1st, 4th, 7th and 14th days of observation, sampling of swabs from the nasopharynx, double collection and re-examination before leaving quarantine” to “Centralized isolation medical observation at 1- e, 2nd, 3rd, 5th, 7th days and dispensary observation at home.
Strict control measures were adjusted from "7-day medical supervision in centralized isolation" to "7-day medical supervision in home isolation" and nucleic acid testing on days 1, 4 and 7.
2. Uniform standards for delimitation of closed control zones and zones of medium and high risk
The two types of risk demarcation standards and prevention and control measures should be linked and consistent with each other, and the concept of medium and high risk areas should be used uniformly to form a new risk and control delineation plan. In the high-risk area, "stay at home, door-to-door service" is being implemented.
No new infections for 7 consecutive days can be reduced to medium risk areas and medium risk areas with no new infections for 3 consecutive days. In the rest of the districts, people who have a history of living in high-risk areas in the past 7 days will be subject to 7 days of centralized isolation and medical observation.
In the medium risk zone, the principle of "stay away from this zone and collect things at different peaks" applies, and not a single new infection for 7 days in a row was reduced to the low risk zone. In the remaining areas, people who have a history of living in a medium-risk area in the past 7 days will be subject to 7 days of home health care.
3. Improve epidemic monitoring requirements
The frequency of nucleic acid testing for high-risk occupational groups will be adjusted, and nucleic acid testing of personnel in direct contact with arriving personnel, items, and the environment will be increased to once a day, and nucleic acid testing for personnel with frequent contact and high mobility will be increased to twice a week. Antigen testing is being added as an additional means of epidemic monitoring. Primary care and health care facilities can increase antigen testing for suspicious patients and people in medium- and high-risk areas while fighting the epidemic.
Fourth, optimize the strategy for detecting regional nucleic acids.
Refine nucleic acid testing plans for regions with different populations, and conduct studies and conclusions for provincial capital cities, cities with a population of more than 10 million people, large cities and rural areas to determine whether the source of infection was clear after the outbreak, there is whether the risk of community transmission, whether the chain of transmission is clear, etc. Depending on the size of the risk, according to the principle of classification and classification, determine the scope and frequency of regional nucleic acid testing.
