(Fighting against New Coronary Pneumonia) The epidemic is still in the critical stage, and the "change" and "unchanged" of China's anti-epidemic

  China News Agency, Beijing, March 25 (Reporter Ying Ni) From March 1 to 24, China has reported more than 56,000 local infections, and the situation of epidemic prevention and control is still severe and complicated.

The epidemic is at a critical stage. How should China respond? From the press conference of the Joint Prevention and Control Mechanism of the State Council of China on the 25th, it can be seen that there are two "constant" and one "change" in China's epidemic prevention and control, namely: continue to adhere to The general policy of "dynamic clearing" remains unswerving, and continues to emphasize that vaccination, especially the elderly over 60 years old, should be fully connected, and the ninth edition of the diagnosis and treatment plan will be revised from time to time for Omicron.

Continue to adhere to the general policy of "dynamic clearing" unswervingly

  The Joint Prevention and Control Mechanism of the State Council emphasized on the 25th that the number of newly confirmed cases in the world has rebounded for the second consecutive week, and the number of new local infections in China is still at a high level, and will continue to adhere to the general policy of "dynamic clearing".

  Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention, said that in view of the current epidemic situation in China, striving to achieve dynamic clearing in a short period of time is still the most economical and effective new crown prevention and control strategy.

  He introduced that due to the rapid spread of the Omicron strain and the large number of infected people, the total number of deaths and social harm and impact caused by the epidemic have not been alleviated.

A study has made a comparative analysis of the case fatality rate and mortality rate in the relevant countries from August to October 2021 and from November 2021 to January 2022. The first three months were dominated by delta strains. Lord, the last three months were dominated by the Omicron strain.

The latter case fatality rate did drop, but the total number of deaths or fatalities due to the outbreak over the same period was higher than the number of deaths over the same period when the delta strain was endemic.

"The hazard of the Omicron strain is still serious, and COVID-19 is not a 'big flu'."

Vaccination, especially for the elderly over 60 years old

  According to Wang Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Prevention, there are more than 264 million elderly people aged 60 and over in China, of which more than 212 million have been vaccinated against the new coronavirus.

From the current monitoring results, the incidence of adverse reactions in the elderly over 60 years old is lower than that in other age groups, and it does not show that the elderly over 80 years old are more prone to adverse reactions.

  He pointed out that we have always emphasized that the elderly are one of the highest priority groups for the new crown virus vaccine.

At present, the new coronavirus vaccine has requirements for the lower limit of age, and there is no upper limit for the age, as long as people over 3 years old can be vaccinated.

  According to Lei Zhenglong, deputy director and first-level inspector of the Bureau of Disease Control and Prevention of the National Health Commission of China, up to now, the vaccination rate of the elderly over 60 years old in Jiangxi, Anhui, and Shandong provinces has exceeded 90%, and Chongqing, Henan, Hubei, and Guizhou have , Hebei, Sichuan, Yunnan seven provinces and cities more than 85%.

Because most of the elderly have underlying diseases, once infected with the new crown virus, the risk of severe illness and death is higher than that of other groups. After vaccination, the risk of severe illness and death of the elderly can be effectively reduced. , and those who meet the conditions must complete the booster immunization in time.”

Changing with time: Ninth edition of the diagnosis and treatment plan revised for Omicron

  Wang Guiqiang, director of the Department of Infectious Diseases at the First Hospital of Peking University, said that Omicron is characterized by strong contagion, rapid iteration, and short incubation period, allowing large-scale outbreaks in a short period of time.

The ninth edition of the diagnosis and treatment plan has been adjusted according to these characteristics, mainly emphasizing "moving the gate forward", that is, emphasizing early detection, early reporting, early isolation, and early treatment; emphasizing classified management, among which light cases are centrally isolated and managed, and it is not necessary to go to designated points. Hospital; in terms of treatment, not only pay more attention to the elderly group, but also incorporate antiviral drugs into the diagnosis and treatment plan; timely identify the population at risk of aggravation; emphasis on prevention, emphasis on strengthening vaccination, should be fully connected, and those who meet the conditions must be strengthened immunity.

  At the same time, he also introduced that the ninth edition of the diagnosis and treatment plan clarified that aerosol transmission, that is, air transmission, can occur in relatively confined spaces, which is also a very important feature of Omicron's strong infectiousness.

  In addition, the ninth edition of the diagnosis and treatment plan also clarified the clinical manifestations of Omicron Virus, that is, most patients showed upper respiratory tract infection, and pneumonia was rarely manifested, because Omicron Virus mainly existed in the upper respiratory tract in large quantities, and the clinical manifestations There are many similarities with the flu, such as coughing, sneezing, nasal congestion, etc., so it still requires high attention.
