Just one week after BA.5 had outcompeted all other Covid strains become dominant in the U.S., a new highly-mutated Omicron subvariant has arrived which may begin the cycle all over again.
BA.2.75 has a large number of mutations when compared to its sister Omicron lineages. Some of those adaptations could allow the virus to bind onto cells more efficiently, said Matthew Binnicker, director of clinical virology at the Mayo Clinic in Rochester, Minnesota. BA.2.75 was first sequenced in May in India, where it has spread rapidly.
A very early analysis of data from India by Raj Rajnarayanan — who is Assistant Dean of Research, Nyitcom at Arkansas State University — indicates that BA.2.75 may have a growth advantage over BA.5. It is unclear, as yet, whether BA.2.75 makes people sicker than previous variants.
BA.2.75 (#Centaurus) still didn't remove its foot from the gas pedal in India!

Just as the Omicron wave may have broken across the U.S. comes word of another version of the more transmissible variant, dubbed BA.2. It’s been nicknamed by some “stealth Omicron” because it seems to evade identification better than its predecessor.
While other new variants that seemed worrisome — like Mu or Lambda — have had little impact, and details remain sketchy, early indications are that BA.2 seems to be spreading even in countries where the original Omicron lineage, BA.1, is dominant.
In Denmark, a country whose Covid policies are often contrasted with the U.S., BA.2 now accounts for nearly half of the test samples sequenced. In the final week of December, according to data from Statens Serum Institut under the auspices of the Danish Ministry of Health, the subvariant accounted for 20% of all Covid cases in Denmark. By the second week of January, its share had risen to about 45% of the total.
