The CNBC report, citing data from the US Centers for Disease Control and Prevention (CDC), was released on Friday (December 30) local time. existing species XBB.1.5 It accounts for around 41% of new infections across the country. It almost doubled from 21.7% last week. This subspecies was found to more than double in all populations. Weeks up to December 24
Scientists and health officials have been eyeing a subspecies of the omikron family. XBB It has been for several months due to many mutations that could bypass the immune vaccine against COVID-19, such as the booster needle forOmicron sprayed and less effective Or sprayed and still infected
XBB was first seen in India last month. last August It quickly became a staple there, including in Singapore. It then developed 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. making it easier for people to get infected
This is consistent with the information of Mr. Yunlong Richard Gao, a scientist and assistant professor at Peking University. Who announced information via Twitter on Tuesday (Dec. 28) that XBB.1.5 not only evades immunity as well as the immune evasion strain XBB.1, but also attaches to cells through the main receptor better as well
A study by Columbia University Faculty of Science. It was published in the journal Cell a few days ago, it warned that the increase in fires like XBB could undermine the effectiveness of protective vaccines.COVID-19 Currently, this has led to a large increase in infections even after vaccination and re-infection.
