Omicron’s new XBB.1.5 variant is spreading rapidly in the United States
According to NBC and other US media reports, the US Centers for Disease Control and Prevention has declared the new XBB. 1.5 is spreading rapidly in the United States. Right now, 40% of confirmed cases of new crowns are infected with this new variant, up from 20% a week earlier. In northeastern China, about 75% of confirmed cases are infected with XBB. 1.5.
Barbara Barbara, director of the division of respiratory viruses at the US Centers for Disease Control and Prevention, said there was no indication that XBB. 1.5 causes more severe disease than other omecron variants. While COVID-19 hospitalizations are increasing across the country overall, there is no increase in hospitalizations in the Northeast.
Pecoutz, a virology expert at Johns Hopkins University in the United States, said that XBB. 1.5 has an additional mutation for better cell binding. Columbia University scientists have warned in a study that the growing number of Omicron XBB subvariants could further undermine the effectiveness of the new corona vaccine and lead to a surge in breakthrough infections and reinfection.
