The rapid spread of Omicron has done harm to the whole world, and it has set off a new wave of communication peak in COVID-19, COVID-19. At present, most cases in China belong to BA. 1 and BA.2 families of Omicron. Scientific research shows that the mutant of BA. 1/Omicron gene is different in that there are more than 30 gene mutations in its stinging egg protein, which is the primary reason why it can escape or spread quickly. And at this stage, all vaccines introduced in the world have different abilities to prevent the infection of Omicron strain. However, vaccination can still reduce the incidence of hospitalization and serious infection, especially for those infected by booster injection.
According to a scientific research data recently released by CDC. This research * * * analyzed nearly 700,000 infected people, and found that compared with Delta strain, the risk of hospitalization, critical illness and death of Omicron infected people decreased by 53%, 74% and 965,438 0% respectively. Other information from abroad also shows that most patients with Omicron are mild diseases, and only a few patients need oxygen, and the development trend is COVID-19. In the past, most patients had oxygen supply, and even anesthesia machines were common.
Even in this epidemic in China, the main performance is the same. Most of the symptoms are just muscle pain, itchy throat, dry cough and dry mouth, and only a few patients have fever symptoms. Although the mortality rate has not increased significantly, it is uncertain whether the side effects of the virus are smaller or because of the lag effect of infection death, which needs further scientific research data to be clear. In other words, Auger is "much softer" than Bitta. However, researchers note that although the "risk factor" is reduced, Omicron is much more contagious than Delta, so we should not take any chances. Naturally, this is also overseas data information, for your reference only.
According to the statistical analysis of scientific research, 80% of the infected people in Omicron are under 50 years old. At present, children account for nearly half of the infected people in Tianjin. Research by Hong Kong University virologist Jin Dongyan shows that Omicron is more highly pathogenic in children than previous strains. Moreover, the academician of Zhang Boli Academy of Engineering also pointed out that the vaccination rate of children and adolescents is relatively low, and parents' concept of actively seeking medical treatment is not high, which is a weak point in epidemic prevention and control. We should pay more attention to safety protection.
Zhang Wenhong, head of the National Center for Infectious Diseases and director of the Infectious Diseases Department of Huashan Hospital affiliated to Fudan University, said that under normal circumstances, whether it is the level of group immunity or the immune barrier built according to vaccines, it will be the last severe winter.
To put an end to the COVID-19 epidemic, there are two prerequisites: First, we must create a higher level of immunity among people. This level of immunity may be based on high-quality vaccination, or natural infection (people who have not been vaccinated), and secondly, people have developed reasonable and effective treatment drugs for the virus.
From the analysis of authoritative experts and scientific research reports at this stage, it seems that we should prevent Omicron at this stage, or maintain a stable lifestyle, wear masks, pay attention to hygiene, avoid gathering, and vaccinate, especially children. At the same time, we should be optimistic about epidemic prevention and control, as Professor Zhang Wenhong said: We firmly believe that no matter what genetic variation the virus will produce in the future, people will be able to cope with it.
