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.

I've seen videos using infra red cameras of respiratory aerosols and the containment that a cloth or disposable mask offers. They are not perfect by any means but they contain thousands of those minuscule virus particles that are trapped in the aerosols. Thousands of those virus particles are trapped in the masks are better than none.
Cloth and those disposable masks are not designed for protection. We were always told they are not protective and if anyone does not know that by now, they have not been listening. Those masks are designed for source control and for those masks to be effective, everyone wears a mask. Your mask protects me and my mask protects you. THAT is why masks should be mandated in schools for children who can not be vaccinated yet. There should be absolutely no debate about that.
