As the crown disease XBB strain appears in China, the local people pay attention to whether this strain will cause secondary infection, But virus experts call on the public to worry about the risk of secondary infection.Not According to CCTV's Monday (January 2), Xu Wenbo, director of the China Centers for Disease Control and Prevention Center, confirmed at a press conference on December 20, 2022 that XBB and another coronal virus strain BQ.1 has been introduced to China and has not yet formed advantages in China, but the spread of these strains will gradually increase.Not BQ.1 and XBB strains have also appeared in Shanghai in economic town.Not Domestic and foreign experts predict that as the Omikon subtype XBB.1.5 is more likely to infect the human body, it will become the main poison in the world in a short time.The report quoted scientists that due to high immunization ability, XBB.1.5 has quickly become the number one popular strain in the United States.Not XBB will lead to secondary infection and then become a topic of attention from netizens, and also rush to the Weibo hot search list.Not However, Jin Dongyan, a professor at the School of Biomedicine and virus expert of the University of Hong Kong, pointed out on Sunday (January 1, 2023) that XBB.1.5 has not caused significant changes in the number of infections, hospitalization, and death in the United States.XBB.1.5's pathogenic force and secondary infection risk do not have to worry too much; except for a certain degree of immune escape ability, other aspects of changes are relatively small.Not For the information of the Internet, XBB.1.5 poison strains mainly attack the cardiovascular and cerebrovascular and gastrointestinal, which can cause diarrhea and lead to the disconnection of Mongolian stone dispersal.But "mainly attack cardiovascular and stomach" is nonsense.Not As for the probability of re -infection related to XBB, Wang Xinyu, deputy director of Huashan Hospital affiliated to Fudan University, said that this mainly depends on two aspects. One is that if the virus has been mutated and the cross protection effect is reduced, it may cause it may causeInfection; the second is to see the level of human antibody.Not Wang Guiqiang, director of the Department of Infectious Diseases of the First Hospital of Peking University, believes that patients who are infected with BF.7 and BA.5.2 strains now have risks of infection.Not Wang Guiqiang also said that there is generally a period of interval in secondary infection, and the probability of re -infection of the same strain is extremely low.Even infected, there are no obvious symptoms, generally mild.
