China News Service, Beijing, March 18 (Reporter Li Chun) Since March, the current round of COVID-19 in China has spread to 28 provinces. At present, there are 420 medium- and high-risk areas in the country. high number of confirmed cases.

Wang Hesheng, deputy director of the National Health Commission and director of the National Centers for Disease Control and Prevention, pointed out that China will continue to face a situation of epidemic prevention and control dominated by the Omicron virus strain in many places at the same time, and the prevention and control situation is becoming increasingly severe and complex.

　　What is the reason for the current round of epidemic in China?

Will the "dynamic zeroing" strategy still be adhered to?

How to deal with the current severe situation?

At a press conference held by the State Council Information Office on the 18th, relevant officials of the National Health Commission answered this one by one.

　　Since December last year, the global new crown pneumonia epidemic has entered the fourth wave of epidemic peak, and it is still at a high epidemic level.

Especially since the beginning of this year, the epidemic situation in China's neighboring countries and regions has risen rapidly, and the "pressure difference" between China's epidemic level and the level of the epidemic has continued to increase.

　　Talking about the reasons for the current round of the epidemic in China, Wang Hesheng said that the traceability results of the flow survey showed that the recent local cluster epidemics in China were all caused by imported sources.

After the Omicron variant is infected, most of them are mild cases and asymptomatic infections, the source of input is more hidden, and the transmission methods are more diverse.

In addition, there are multiple transmission chains of the epidemic in many places, and the source of the epidemic is complicated, which brings huge challenges to the traceability and prevention and control work.

　　He also mentioned that some places believe that the Omicron variant has mild symptoms and is "flu-like", that the mind is slack and paralyzed, that there is a mentality of "resting and slowing down", lack of preparation in all aspects, and the need for normalized prevention and control. Emergency response relaxed requirements.

　　On March 17, the Standing Committee of the Political Bureau of the CPC Central Committee held a meeting to analyze the situation of the new crown pneumonia epidemic and deploy strict measures to prevent and control the epidemic.

The meeting pointed out that "overcoming paralysis, war weariness, fluke mentality, and slack mentality, and in the spirit of waiting for time and time, we will pay close attention to the work of epidemic prevention and control."

　　"These characteristics of this round of epidemic require us to further improve the sensitivity of monitoring and early warning, improve the monitoring mechanism triggered by multiple points, and effectively improve the ability of 'early detection' of the epidemic." Talking about how to deal with such an increasingly severe epidemic prevention and control situation Wang Hesheng pointed out that it is necessary to guide the key areas of the epidemic to speed up nucleic acid screening and the investigation, flow adjustment, and control of risk personnel, so as to realize the "dynamic clearing" of the society as soon as possible.

　　"Dynamic clearing" is regarded as a "magic weapon" for China's epidemic prevention and control.

The goal of this strategy is to control the epidemic at the lowest social cost and in the shortest possible time. The core of this strategy is rapid response and precise prevention and control.

"Quick" is reflected in rapid detection, rapid disposal, and rapid blocking, while "accuracy" is reflected in all aspects of the entire chain of epidemic prevention and control, including investigation, isolation and control, community prevention and control, and clinical treatment.

　　Thanks to the "dynamic clearing" policy, the total number of people infected with new coronary pneumonia in China is very small, and the epidemic can be quickly extinguished within one to two maximum incubation periods, and the relationship between epidemic prevention and control and economic and social development has been balanced.

"China's anti-epidemic practice shows that insisting on 'dynamic clearing' is a line of defense that our country with a population of more than 1.4 billion must guard against the epidemic. Contribution." Wang Hesheng said.

　　At the same time, China is constantly improving various measures, striving to prevent and control the epidemic more scientifically and accurately.

For example, the ninth edition of the New Coronary Pneumonia Diagnosis and Treatment Program was announced recently, with five major revisions, and proposed measures such as adding antigen testing as a supplement to nucleic acid testing, and implementing centralized isolation management for mild cases.

　　Jiao Yahui, director of the Medical Administration and Medical Administration Bureau of the National Health and Medical Commission, pointed out that the revision of the diagnosis and treatment plan is based on the anti-epidemic practice in China over the past two years, especially the observation and research on clinical cases of the delta strain and the Omicron strain. .

"The adjustment of the (ninth) edition of the diagnosis and treatment plan does not mean that the prevention and control policy is relaxed, but more scientific, more accurate, and more targeted."

　　On the other hand, promoting new coronavirus vaccination and strengthening immunization, and continuously improving vaccine coverage are still effective measures to prevent and control the epidemic and protect people's health.

Among them, the completion of full-course immunization and booster immunization are particularly important for the elderly.

　　Zeng Yixin, deputy director of the National Health Commission, pointed out that the immune function of the elderly is relatively weak, and most of them suffer from various underlying diseases. Once infected with the new coronavirus, the risk of severe illness and death is much higher than that of young people.

Taking the recent epidemic in Hong Kong as an example, the mortality rate of vaccinated people is 0.04%, and the mortality rate of those who have not been vaccinated or not fully vaccinated is 1.25%, and 90% of those who died were elderly.

　　Zeng Yixin also said that vaccination has a good protective effect on preventing severe illness and death.

It is hoped that people who meet the requirements for enhanced immunization, especially the elderly and people with underlying diseases, can take the initiative to vaccinate and vaccinate in a timely manner, so as to increase the protection of their own health and contribute to the prevention and control of the epidemic in the whole society.
