CHICAGO — The highly transmissible Omicron variant of the SARS-CoV-2 virus — the most common form of which is known as BA.1 — now accounts for nearly all of the coronavirus infections globally, although dramatic surges in coronavirus disease 2019 cases have already peaked in some countries.

Trevor Bedford, a computational virologist at Fred Hutchinson Cancer Center who has been tracking the evolution of SARS-CoV-2, wrote on Twitter on Friday that BA.2 represents roughly 82% of cases in Denmark, 9% in the UK and 8% in the United States, based on his analysis of sequencing data from the GISAID database and case counts from the Our World in Data project at the University of Oxford.

As with other variants, an infection with BA.2 can be detected by coronavirus home tests kits, though they cannot indicate which variant is responsible, experts said.Some early reports indicate that BA.2 may be even more infectious than the already extremely contagious BA.1, but there is no evidence so far that it is more likely to evade vaccine protection.
