As the United States enters the thick of respiratory virus season, a highly mutated COVID-19 variant called BA.2.86 is spreading and causing an increasing proportion of cases across the country.
BA.2.86 is notable for having more than thirty mutations on its spike protein relative to BA.2. [1] The subvariant , which was first detected in a sample from 24 July 2023, [ 2 ] is of concern due to it having made an evolutionary jump on par with the evolutionary jump that the original Omicron variant had made relative to Wuhan-Hu-1, the ...
The new Covid strain was placed under the World Health Organisation’s monitoring list on Thursday due to the ‘large number of mutations it carries’
He said it remains to be seen whether BA.2.86 will be able to out-compete other strains of the virus or have any advantage in escaping immune responses from prior infection or vaccination.
According to the WHO, BA.1, BA.1.1, and BA.2 were the most common sublineages of Omicron globally as of February 2022. [213] BA.2 contains 28 unique genetic changes, including four in its spike protein, compared to BA.1, which had already acquired 60 mutations since the ancestral Wuhan strain, including 32 in the spike protein.

CDC is tracking a new lineage of the virus that causes COVID-19. This lineage is named BA.2.86, and has been detected in the United States, Denmark and Israel. ... "Even if a highly mutated new ...
There were two new BA.2 subvariants detected in the US state of New York, which are BA.2.12 (or B.1.1.529.2.12) and BA.2.12.1 (or B.1.1.529.2.12.1), both of which have a significant growth advantage of 23–27% over BA.2 and contributing to a rise in infections in central New York, centred on Syracuse and Lake Ontario, which later became ...
BA.2.12.1 isn't the only version of BA.2 that has caught scientists' attention. Another sublineage, BA.2.12, also seems to be pushing up cases in New York , and several more are circulating in ...
