The CNBC report, which cites data from the US Centers for Disease Control and Prevention (CDC), was released on Friday (Dec. 30) local time. current species XBB.1.5 It accounts for about 41% of new infections nationwide. That’s almost doubled from last week’s 21.7%. This subspecies was found to be more than double in each population. Weeks until December 24th
Scientists and health officials have observed a subspecies of the omikron family. XBB extension It has been for several months due to many mutations that could evade the immune vaccine against COVID-19, such as the booster needle forOmicron injected and less effective OR injected and still infected
XBB was first seen in India last month. last August. It quickly became a staple there, even in Singapore. It then evolved into subspecies families such as XBB.1 and XBB.1.5.
Andrew Pecosz, a virologist at Johns Hopkins University, said: XBB.1.5, unlike family members, has additional mutations that enhance cell adhesion. thus making it easier for people to get infected
This is consistent with information from Mr. Yunlong Richard Gao, scientist and assistant professor at Peking University. Che posted information via Twitter on Tuesday (December 28) that XBB.1.5 not only evades immunity as well as the XBB.1 immune evasion strain, but also attaches itself to cells via the core receptor.
A study by Columbia University’s Faculty of Scientists. Published in the journal Cell a few days ago, it warned that the increase of sub-strains such as XBB could undermine the effectiveness of protective vaccines.COVID-19 At present, this has resulted in a sharp increase in infections even after vaccination and re-infection.
