The World Health Organization has listed the new variant under "Omicron subvariants under monitoring". Since the variant has been mostly attributed to cases in India, the Center For Disease Control (CDC) has not yet listed it as a variant of concern or emerging variant. Although cases of BA.2.75 have popped up in the US.
In addition, the variant has been detected in at least 10 other countries including Australia, UK, and Canada.
BA.2.75 is considered highly transmissible but the severity of disease is not clear as there have not been enough cases to understand its impact fully.
WHO names strains of Covid to help communicate information to the public about each one and so people can distinguish between variants. Notably they've kept to naming variants according to the Greek alphabet to prevent stigma from arising.
However, Ostale believes naming subvariants like BA.2.75 is important so people do not just associate fast-spreading subvariants with the original one.
\u201c2/5\n\nWHO isn't doing what they should do, name the variants and sublineages that are spreading more. For people to get it. They want people to not get it, to get confused, to think it's still omicron=mild and so on.\u201d
