What to Know About the New BA.2.75 Omicron Subvariant

Now spreading in at least 10 countries, but it's too soon to tell how virulent or deadly it is

Even as BA.4 and BA.5 continue to climb the charts, crowding out earlier Omicron subvariants, scientists are warning about an even newer strain: BA.2.75.

So far, the subvariant has made its way to at least 10 countries in Asia, Europe, North America, and Australia.

BA.2.75 was first detected in India in early May and has been spreading quickly since. It made up almost 25% of samples there as of June 2 and is competing with BA.5 and BA.2, according to Katelyn Jetelina, PhD, MPH, an epidemiologist at the University of Texas School of Public Health in Dallas.

A more recent analysis of coronavirus sequencing, posted by a scientist in Australia, suggested the proportion of cases has jumped much higher as of July 8 -- growing to nearly half of COVID cases sequenced in India.

A CDC spokesperson confirmed in an email to MedPage Today that there have been two cases of BA.2.75 detected in the U.S., with the first specimen collected on June 14. This is still not enough to get on the CDC's variant tracker, where it is still unlisted.

Like BA.2.12.1 and BA.45, Omicron 2.7.5 is a descendant of BA.2

2. Yes. But the numbers are too low to conclude that it is viable.

Anyway, Omicron is mutating faster than influenza, and that is not good news.
