COVID's Omicron variant surfaced in early November 2021 and has been wreaking havoc ever since. With several mutations and substrains, it has become extremely prevalent and contributes to a vast majority of infections. Its sub-variants, BA.4 and BA.5, have been declared the most dominant in the U.S. and are said to be driving the rise in the number of COVID cases in India and other countries.
Now, another Omicron subvariant has come to the fore. Scientists across the globe have alerted countries of a new subvariant, called the BA.2.75, which has cropped up in India. According to an Israeli health expert, this new variant could be "alarming" in nature.
