The state of Washington has logged two confirmed cases of BA. 2, a new subvariant of COVID-19. "A subvariant, basically, just means it’s a virus that has a different sequence. One of the things that we do know, is it looks as if it’s related to omicron variant," said Dr. Ken Stedman, professor of biology at Portland State University. It is nicknamed the "stealth variant" because health officials say it is hard to detect. Experts say it doesn't matter how many variants we have.
