On July 21, the press conference of the Joint Prevention and Control Mechanism of the State Council was held in Beijing.
Regarding the scientific and accurate prevention and control of the new crown pneumonia epidemic, the relevant person in charge of the National Health Commission responded.
The ninth edition of the prevention and control plan has these changes
He Qinghua, a first-level inspector of the National Health Commission's Bureau of Disease Control and Prevention, introduced in response to a reporter's question about vaccination against the new crown vaccine. As of July 20, the cumulative number of people who have been vaccinated with the new crown vaccine and the number of people who have been vaccinated throughout the country accounted for the total population of the country. 92.08% and 89.68%.
Among them, 236.169 million people over the age of 60 were vaccinated, and 223.11 million people had completed the whole course of vaccination, accounting for 89.45% and 84.5% of the elderly population, respectively.
In the newly released ninth edition of the prevention and control plan, the management of risk personnel, the division of lockdown control areas, and the requirements for epidemic monitoring have been adjusted and improved.
He Qinghua introduced that from April to May this year, the comprehensive team of the Joint Prevention and Control Mechanism of the State Council carried out a four-week pilot program to optimize the prevention and control measures of the new crown pneumonia epidemic in seven inbound cities including Dalian, Suzhou, Ningbo, Xiamen, Qingdao, Guangzhou and Chengdu. Work.
Wang Liping, a researcher from the Communication and Prevention Division of the Chinese Center for Disease Control and Prevention, further introduced that during the pilot work, the comprehensive team mainly observed and verified four categories: immigrants, close contacts, people in closed and controlled areas, and employees in high-risk positions in closed-loop management. The characteristics of positive detection and positive conversion time of risk personnel.
The study found that the average incubation period of Omicron mutants was shortened, mostly 2 to 4 days, and most infected people could be detected within 7 days.
Therefore, the isolation and control time for close contacts and inbound personnel has been adjusted from "14 days of centralized isolation medical observation + 7 days of home health monitoring" to "7 days of centralized isolation medical observation + 3 days of home health monitoring".
"Such an adjustment is to further optimize the prevention and control measures according to the epidemic characteristics of the Omicron variant, and it will not increase the risk of the spread of the epidemic. It is a manifestation of precise prevention and control." Wang Liping said, for example, the low risk of going out across regions Regional personnel do not need to take isolation control measures, but are required to complete two nucleic acid tests within 3 days and conduct personal health monitoring.
He Qinghua also said that the ninth edition of the prevention and control plan is to optimize the prevention and control measures, not to relax the prevention and control: "The key to the ninth edition of the prevention and control plan is to control the key points that should be controlled and implement the measures that should be implemented. In place, resolutely cancel what should be canceled."
Current vaccines still work
He Qinghua introduced that since July, the epidemic situation across the country has generally fluctuated at a low level. Recently, the epidemic situation in a few areas has rebounded, showing a trend of multiple distribution and frequent occurrence in multiple places. The number of local infections reported in a single day has increased.
In the past week, the epidemic has spread to 78 cities in 21 provinces, of which 7 provinces have reported more than 100 cases of infection.
The epidemics in Lanzhou of Gansu, Beihai of Guangxi, and Zhumadian of Henan are still in the advanced stage, and the risk of social transmission is relatively high.
At present, the comprehensive group of the joint prevention and control mechanism of the State Council has dispatched working groups to relevant provinces to guide local governments to control the epidemic in the shortest time and at the lowest cost.
Mi Feng, spokesperson of the National Health and Health Commission, emphasized that we must adhere to "foreign defense against imports and internal defense against rebound", adhere to "dynamic clearing", strictly implement the ninth edition of the prevention and control plan and the "nine prohibitions" requirements, and do not slack off. It is necessary to normalize prevention and control, take active prevention, early detection, and fast disposal, comprehensively improve the work efficiency of the whole chain, and strive to be scientific, accurate, and convenient for the masses.
At the press conference, Dong Xiaoping, chief expert of virology at the Chinese Center for Disease Control and Prevention, introduced that the transmission power of the BA.4 and BA.5 subclades of the Omicron variant strains is slightly higher than that of other Omicron variant strains, and its pathogenicity Generally similar to other Ormicron variants.
"The BA.4 and BA.5 subclades still belong to the Omicron variant, and there is no evidence that the existing NPI (non-drug intervention) measures will be ineffective." Dong Xiaoping said, "In other words, my country's existing prevention and control measures are ineffective. The measures are still effective.”
In response to the impact of the BA.4 and BA.5 subclades of the Omicron variant strains, Dong Xiaoping believes that, on the one hand, it is necessary to pay attention to its enhanced transmission power and severe and critically ill cases caused by large-scale outbreaks, timely detection, Effective control; on the other hand, there is no need to over-interpret and panic, because the pathogenicity 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, the first is to complete the basic and booster vaccinations as much as possible, especially for the elderly and patients with underlying diseases, to avoid serious clinical consequences to the greatest extent possible. Second, as always, adhere to routine personal protection. ." Dong Xiaoping said.
"In general, local epidemics can be effectively controlled in a relatively short period of time after the local epidemic occurs, and the impact of the epidemic is relatively limited. The ability and efficiency of local epidemic response and disposal have been further improved." He Qinghua emphasized that all localities should continue to strictly follow the ninth edition. According to the relevant requirements of the prevention and control plan, adhere to the principles of scientific, precise and efficient prevention and control, implement various measures to prevent foreign imports throughout the chain, and continuously improve the sensitivity of epidemic monitoring under normalized prevention and control.
After the outbreak of the epidemic, the measures must be resolute and decisive, adhere to fast control, strive to control the epidemic to the smallest scope in the shortest time, and resolutely prevent the occurrence of large-scale epidemics.
