Recently, a screenshot of "XBB. 1.5 strain has become the number one epidemic strain in the United States, and everyone should stock up on montmorillonite powder, whole intestines and other drugs" spread among WeChat friends, leading people to rush to buy relevant drugs. At the press conference held by the Joint Prevention and Control Mechanism of the State Council a few days ago, Xu Wenbo, director of the Institute of Viral Diseases of the Chinese Center for Disease Control and Prevention, pointed out that XBB and BQ.1 are new variants of Omicron, which have gradually become dominant strains in some European and American countries, and their transmission and immune escape capabilities have increased. However, its pathogenicity is not significantly different from other series of variants of Omicron, and the severity rate and mortality rate have not increased significantly in countries where BQ.1 and XBB are prevalent. The National Health Commission recently issued a notice stating that the prevention and control measures for Class A infectious diseases stipulated in the Law of the People's Republic of China on the Prevention and Control of Infectious Diseases against novel coronavirus infection will be lifted from January 8, 2023; The novel coronavirus infection is no longer included in the quarantine infectious disease management stipulated in the Frontier Health and Quarantine Law of the People's Republic of China; Measures for the control of quarantinable infectious diseases will no longer be taken against people and goods entering the country. So, will this cause a new round of virus epidemic? Xu Wenbo said that in the past three months, it has been monitored that BQ.1 and XBB have been introduced into China, which has not yet formed a communication advantage in China, but its advantages will gradually increase. In response to public concerns, Zhang Boli, an academician of the CAE Member, said recently that after infection with COVID-19, the first thing is to use drugs rationally and rationally, and the second is to be patient. It will take some time for drugs to work. Even the mechanism of "small molecule specific drug" is only to inhibit virus replication, and cannot eradicate the virus. Moreover, the therapeutic window period of these drugs is relatively narrow, and they are only effective within 5 days after infection, and should not be used together with statins. The "main force" against COVID-19 is self immunity. Adjust your physical condition, pay attention to rest, drink plenty of water, eat more fresh fruits and vegetables, ensure nutrition intake, maintain a good mood, and improve your immunity. Xu Wenbo also said that the prevention of BQ.1 and XBB is the same as other Omicron mutants. The measure taken is to monitor whether its pathogenicity has changed and whether its genome has further variation. If there is any change in its clinical characteristics, we will associate it with the characteristics of the genome for research and judgment. (Outlook New Times)
