Francois Balloux, professor of computational systems biology at University College London, said AY.4.2 has two spike mutations found in other coronavirus variants and was first sequenced in April 2020.

The subvariant was “rare” outside Britain and there had been only three cases detected so far in the US, he added.

“As AY.4.2 is still at fairly low frequency, a 10 percent increase in its transmissibility could have caused only a small number of additional cases,” he said. “As such it hasn’t been driving the recent increase in case numbers in the UK.”

Bayroux, director of the UCL Genetics Institute, added: “This is not a situation comparable to the emergence of Alpha and Delta that were far more transmissible (50 percent or more) than any strain in circulation at the time.”

“Here we are dealing with a potential small increase in transmissibility that would not have a comparable impact on the pandemic.” Learn Hebrew in a fun, unique way
