But, as it turned out, this is not quite a high-quality protection. For example, Liana Wen, professor of health policy and management at George Washington University, said cloth masks are useless against the omicron strain of coronavirus.
Instead, the specialist advised wearing surgical masks – unlike rag masks, they provide protection against a new type of pathogen. At the same time, the expert clarified that the fabric version can be worn over the protective one, but only as a decoration.
In the event that you have to find yourself in a place where there is a large crowd of people, it is most appropriate to use masks and respirators of the N95 class, Wen said.
