Maybe not all masks but here’s the latest mask guidance and the ordinary cloth mask as Fauci said last year is not very effective because the virus can pass through it except for sneezes or cough droplets. We are thinking of K95 just in case.

Michael Osterholm, director for the Center for Infectious Disease Research and Policy at the University of Minnesota, told CNN this week that people should upgrade from their cloth masks and bandanas to more heavy-duty masks — like N95s and K-N95s.

“We need to talk about better masking. We need to talk about N-95 respirators, which would do a lot for both people who are not yet vaccinated or not previously infected,” Osterholm told CNN. “Protecting them as well as keeping others who might become infected having been vaccinated from breathing out the virus.”
Osterholm said he has had issues with how masking has gone in the United States because people have not taken the best masks — like N95s — as seriously as cloth masks, according to The Hill.
