China News Service, April 6th. Wang Guiqiang, director of the Department of Infectious Diseases of Peking University First Hospital, said today that the virulence of the Omicron strain has decreased relative to previous strains. At present, it is still more harmful than the so-called influenza. Especially in the elderly who are not vaccinated or not fully vaccinated.
On the afternoon of the 6th, the Joint Prevention and Control Mechanism of the State Council held a press conference on the strict and earnest efforts to prevent and control the epidemic.
At the meeting, a reporter asked: Judging from the current report, most of the newly infected people in the local area are asymptomatic and mildly ill. Some people say that Omicron is less harmful. Is that true?
Wang Guiqiang responded that at present, the prevalence of Omicron strains in my country as a whole, asymptomatic infections and mild cases are relatively high.
On the one hand, it is because the virulence of Omicron's own strains has been relatively reduced, with upper respiratory tract infections being the main, lower respiratory tract infections being rare, and the incidence of pneumonia being relatively low.
Second, because of the current background of vaccination, the proportion of severely ill people in the vaccinated population is obviously low.
The third is active nucleic acid screening. Many patients are found during the incubation period, so the proportion of asymptomatic infections is relatively high.
In addition, asymptomatic infections and mild cases are relatively high in young people and young adults infected with the Ormicron strain.
Wang Guiqiang said that the decrease in virulence of the Omicron strain is relative to the previous strains. At present, it is still more harmful than the so-called influenza, especially in the elderly who have not been vaccinated or have not been fully vaccinated.
Data from the Hong Kong Special Administrative Region shows that there are currently more than 1.1 million infected people and more than 8,000 deaths, with a case fatality rate of 0.7%, which is much higher than that of influenza.
In addition, the Hong Kong epidemic data gives us a very important reminder that vaccination is closely related to the case fatality rate.
According to the data on the fatalities in Hong Kong, the fatality rate of unvaccinated patients is 3.2%, the fatality rate of one shot is 0.96%, the fatality rate of two shots is 0.14%, and the fatality rate of three shots is 0.03%.
From this data, three doses of vaccination can effectively reduce the mortality rate after Omikron infection.
Wang Guiqiang pointed out that at present, we cannot be paralyzed. On the one hand, we must adopt active and effective prevention and control strategies.
On the other hand, we must actively promote vaccination and strengthen vaccination efforts, especially for the elderly and those with underlying diseases.
From the current data, the elderly and those with underlying diseases can effectively reduce the harm of the Omicron strain after vaccination.
Here I call on the majority of elderly friends to actively vaccinate, especially to strengthen the immunization. The third injection is very important. Only by protecting the elderly and other high-risk groups with underlying diseases, and vaccinating according to the procedures, can we really reduce the risk of The dangers of Omicron.
