Omicron Covid variant poses very high global risk says WHO
Protect yourself from the Omicron Covid variant with KN95 masks. With about one quarter of the American population still unvaccinated and the Omicron Covid variant threatening, all Americans, whether they are vaccinated or not, should wear masks indoors in public spaces and in places where the coronavirus is still spreading. New cases of the COVID delta variant are still rising in many states, especially those with low vaccination rates.
