The BA.1 subvariant is more transmissible than the original Omicron variant, but it does not appear to cause more severe illness..
The BA.1 subvariant was first identified in South Africa in December 2021. It quickly became the dominant subtype of Omicron in South Africa and has since spread to other countries around the world. In the United States, the BA.1 subvariant accounted for about 55% of Omicron cases in the week ending January 8, 2022..
