The World Health Organization is now closely tracking a subvariant of the delta variant of the coronavirus that causes COVID-19 to evaluate whether it is more infectious than the original delta.
The agency is also seeking to determine whether the subvariant called AY.4.2 is more resistant to the human antibodies that fight the virus, according to its weekly epidemiological update.
“Epidemiological and laboratory studies are ongoing to assess if AY.4.2 confers any
additional phenotypic impacts (e.g. a change in transmissibility or a decrease in the ability of antibodies to block the virus),” said the update.
The AY.4.2 subvariant has been detected in 42 countries, with 93% reported from the U.K., where it accounted for about 6% of all delta cases recorded in the week starting Oct. 3. The WHO is currently tracking about 20 variations of the delta variant.
