Scientific and precise epidemic prevention and control

On July 21, a press conference on the joint control mechanism of the State Council was held in Beijing. The relevant person in charge of the National Health and Health Commission responded to the prevention and control of the epidemic prevention and control of new crown pneumonia.

The ninth edition of the prevention and control scheme has these changes

He Qinghua, a first -level inspector of the National Health and Health Commission's Disease Control Bureau, said in response to the reporter's question on the reporter's question on vaccination of the new crown vaccine. As of July 20, the number of new crown vaccines in the country covered the number of new crown vaccines and the total number of vaccinations, respectively. 92.08%and 89.68%. Among them, the number of elderly people over 60 years of age covered 23.6169 million people, and the number of inoccups was 223.11 million, and the number of people covered 89.45%and 84.5%of the elderly population, respectively.

In the latest release of the ninth edition prevention and control scheme, the management of risk personnel management, the division of control areas, and the requirements of epidemic conditions monitoring are adjusted and improved. He Qinghua introduced that from April to May this year, the State Council ’s joint prevention and control mechanism comprehensive group launched a pilot of optimization of new crown pneumonia epidemic prevention and control measures for new crown pneumonia epidemic in Dalian, Suzhou, Ningbo, Xiamen, Qingdao, Guangzhou, and Chengdu. Work.

Wang Liping, a researcher at the Defense Office of the China Centers for Disease Control and Prevention, further introduced that during the pilot work, the comprehensive group mainly observed and confirmed the four types of entry personnel, close contact, seal control areas and management control areas, closed -loop management high -risk positions. The positive detection of risk personnel and the time characteristics of the Yangyang.

Studies have found that the average incubation period of Omikon variants is shortened, mostly 2 to 4 days, and most of the infected people can detect them within 7 days. Therefore, the time of isolation and control of close contact and immigration personnel is adjusted from "14 days of centralized isolation medical observation+7 Heavenly House Health Monitoring" to "7 -day centralized isolation medical observation+3 Heavenly House Health Monitoring".

"Such adjustments are further optimized to prevent control measures based on the popular characteristics of Omiko's mutant strains. It will not increase the risk of epidemic transmission, which is a reflection of precision prevention and control." Regional personnel do not need to take isolation control measures, but it is required to complete two nucleic acid detection within 3 days and do a good job of personal health monitoring.

He Qinghua also said that the ninth edition prevention and control plan is the optimization of prevention and control measures, and it is by no means relaxing and controlling: "The key to the ninth edition of the prevention and control plan is to control the key points and implement the measures that should be implemented. In place, resolutely cancel the cancellation. "

The current vaccine is still valid

He Qinghua introduced that since July, the national epidemic is generally in a low level of volatility. Recently, the epidemic situation in a few regions has rebounded. In the past week, the epidemic affected 78 cities in 21 provinces, of which more than 100 infected people reported in 7 provinces. The epidemic situation in Lanzhou, Guangxi, and Henan in Gansu is still in progress, and the risk of spreading society is greater.

At present, the State Council ’s joint prevention and control mechanism comprehensive group has sent a working group to relevant provinces to guide the places to control the epidemic at the shortest time and minimum cost. Mi Feng, a spokesman for the National Health and Health Commission, emphasized that it is necessary to adhere to "external prevention input and internal prevention", adhere to the "dynamic clearing zero", strictly implement the ninth edition prevention and control plan and the "nine inaccurate" requirements, and do not relax. Good normalization prevention and control, active prevention, early discovery, and fast disposal, comprehensively improve the efficiency of the entire chain work, and strive to be scientific and accurate and facilitate the masses.

At the press conference, Dong Xiaoping, chief expert of the China Centers for Disease Control and Prevention, introduced that the spread of Omikon's mutant BA.4 and BA.5 Asian branches has increased slightly compared to other Omikon mutations. Generally, it is similar to other Omikon variants. "BA.4, BA.5 sub -branch still belongs to Omikon mutant strains, and there is no evidence to show that the existing NPI (non -drug intervention) measures will fail." The measures can still be effectively cope. "

In response to the influence of the branch of Omikon's mutant BA.4 and BA.5 sub -Asia, Dong Xiaoping believes that on the one hand, it is necessary to pay attention to its enhanced propagation and severe cases of critical illness and severe cases. Effective control; on the other hand, there is no need to over -interpret and panic, because the pathogenic force of the virus has not changed significantly, and the existing vaccine and non -drug prevention and control measures are still very effective. "For personal prevention and control, one is to complete the foundation of the vaccine as much as possible and strengthen inoculation, especially the elderly and basic diseases, to avoid serious clinical consequences. . "Dong Xiaoping said.

"In general, after the local epidemic occurs, the local epidemic can be effectively controlled in a short period of time. The impact of the epidemic is more limited. The response capabilities and efficiency of the epidemic in various places have been further improved." He Qinghua emphasized that all localities should continue to strictly follow the ninth edition of the ninth edition. Relevant requirements for preventing and controlled the prevention and control plan, adhere to the principles of scientific, accurate, and efficient prevention and control, the entire chain implementation of various measures for external prevention input, and continuously improve the sensitivity of epidemic monitoring under normalization prevention and control. After the epidemic occurs, the measures must be resolute and decisive, insist on fast -moving, and strive to control the epidemic in the minimum range in the shortest time, and resolutely prevent the occurrence of a large -scale epidemic.
