There’s another Covid storm looming on the horizon as a new subvariant of Omicron BA.2 appears to be carrying mutations that make it even fitter than BA.5.

The subvariant has very few sequences so far, just 73 were listed on Gisaid at the time of writing, but it has already caught the attention of several leading SARS-CoV-2 investigators, so it’s worth noting.

It looks like BA.2.75 may have the potential to be the driving force for the next SARS-CoV-2 winter wave. You heard it here first!

12th July 2022: An excellent analysis of BA.2.75 from William A. Haseltine at Forbes.com:

“There is no relation between Omicron BA.1 and the other major variants, Alpha, Beta, Gamma, Delta, etc.  BA.4/BA.5 is the dominating strain of Covid-19 today, and we believe BA.2.75 may join them.”
