The strain known as BA.2 currently accounts for about 25% of new COVID-19 cases sequenced by the UW Medicine Clinical Virology Laboratory.
The lab first detected BA.2 in early January. Nationally, the variant of concern is responsible for nearly 35% of new infections, according to data from the Centers for Disease Control and Prevention.
He is hopeful that a potential wave of new cases caused by BA.2 won't eclipse that of the original omicron variant. Emerging data show people who have been recently infected with omicron are likely protected against a symptomatic BA.2 infection.
More research finds booster shots continue to give their recipients a leg up in avoiding a major COVID-19 illness, including from BA.2.
“It's been sort of slowly creeping up over the last six weeks,” said Dr. Alex Greninger, the virology lab’s assistant director and an assistant professor of lab medicine and pathology at the UW School of Medicine in Seattle.

“It’s going to be interesting to see what the end of April, beginning of May, what that time period will look like,” said Greninger.
