DEVELOPING: New omicron subvariant that may be more resistant to antibodies, has now spread to 26 countries
Another omicron subvariant was determined to have spread to more countries in the week through Oct. 16 from the previous week, and it may be even more resistant to antibodies than other versions of the virus, according to the World Health Organization.
In its latest weekly epidemiological update, the agency said XBB, a BA.2.10.1 and BA.2.75 recombinant with 14 additional mutations in the BA.2 spike protein, was reported in 26 countries. “Available preliminary laboratory-based evidence suggests that XBB is the most antibody-evasive SARS-CoV-2 variant identified to date,” said the agency, adding that for now, it does not appear to create more severe illness than other variants.
