A day after the COVID-19 omicron variant was confirmed in California, both Colorado and Minnesota confirmed cases of their own.

The Colorado state’s department of health says a woman who traveled to southern Africa is exhibiting “minor symptoms.” The patient was fully vaccinated but did not obtain a booster shot.

Minnesota’s health officials say a man who attended an anime convention in New York City tested positive for the variant and had no history of international travel. The man was fully vaccinated and received a booster shot in early November.

With three confirmed cases of the omicron variant, the White House announced that vaccinations are on the rise. The Biden administration said Thursday that 2.2 million vaccine doses were administered in the last 24 hours — the highest single-day total since May.

This comes as President Joe Biden laid out plans to fight COVID-19 over the winter, which include expanding booster access, expanding vaccine access for kids, offering free at-home rapid tests, extending the mask mandate for public transit, and testing international travelers.
