Hangzhou, Zhejiang Province, China, detected evolutionary branches such as Omikon XBB and BQ.1 among the immigration personnel.
According to the Hangzhou Daily, the monitoring of the virus strains shows that the crown virus strains detected in Hangzhou in recent week are BA.5.2 and BF.7 of Omikon, of which BA.5.254.17%, BF.7 accounts for 45.83%.At the same time, in the closed -loop management entry personnel, the evolutionary branch virus strains such as Omicor Rongjon, such as XBB, BQ.1, and BQ.1.19 were also detected.
Bosom strains, BQ.1 and XBB, etc. In some European and American countries, they have become the main popular strains, mainly manifested as increased communication power and immune escape ability.However, the data also shows that the pathogenic force is not significantly different from the previous strains, and the severe increased rate and mortality have not increased in countries with popular XBB and BQ.1.
As for the risk of secondary infection, XBB and BQ.1 are both sub -branches of BA.5. The immune escape ability of the above strains is enhanced, which is different from the popular BA.5 in China.After a period of time infection, the level of protection has decreased. In the case of a strain with strong immune escape ability, the risk of infection will increase.
However, the infection will mainly occur in some low immunity. The normal immune function is relatively small infected in a short period of time, and the symptoms of infection are usually slightly milder than the first time.
