Q. Is a 3-ply face mask effective against omicron variant of Coronavirus?

Answer

However, a 3-ply surgical face mask is also good alternative to N95 mask because it can prevent contracting of infection from infected droplets from another infected person. Therefore, a 3-ply face mask is also effective against omicron variant of the coronavirus.
