On the afternoon of March 25, the joint prevention and control mechanism of the State Council held a press conference to introduce the scientific and accurate and unremitting efforts to grasp the epidemic prevention and control work, and answer questions from the media.
In response to the question of whether the new crown virus is developing towards influenza, Wu Zunyou, chief expert of epidemiology of the Chinese Center for Disease Control and Prevention, stressed that the harm of the Omiljun strain is still serious, and the new crown pneumonia is not a "big flu". At the same time, he reiterated that in view of the current epidemic situation on the mainland, striving to achieve dynamic clearance in a short period of time is still the most economical and effective COVID-19 prevention and control strategy.
With the increasing proportion of covid-19 vaccinations in the population, the population's immunity to the new crown virus continues to increase, and the pathogenicity of the Aomi Kerong mutation strain itself is not as strong as other strains, the clinical severity of infected people is indeed reduced according to the proportion of each hundred patients.
But Wu Zunyou reminded that asymptomatic infected people are only a concept of a point-in-time state, and today's asymptomatic infected people may also become mild or ordinary cases tomorrow or the day after tomorrow, and we should pay more attention to their high and low infectivity.
Due to its rapid transmission rate and large number of infected people, the total number of deaths caused by the epidemic and the social harm and impact have not been alleviated. Some studies have made a comparative analysis of the case fatality rate and mortality rate in the two time periods of August-October 2021 and November-January this year in relevant countries, and the first three months were dominated by the epidemic of Delta strain, and the next three months were dominated by the epidemic of Theomexron strain. The case fatality rate during the Omiljung strain epidemic did decline, but the total number or mortality rate due to the outbreak during the same period was higher than the number of deaths during the Delta strain epidemic. This shows that the epidemic of the Omiljung strain has not reduced the overall harm to a country.
Wu Zunyou stressed that the mainland is a large population country, a very small morbidity or mortality rate, multiplied by the population base of 1.4 billion, the absolute number will be very large. Only by achieving dynamic clearance can we eliminate the hidden dangers of the epidemic, avoid the run on medical resources that may be caused by large-scale population infection, and prevent the possible death of a large number of elderly people or people with underlying diseases.
