Masks May Reduce Viral Dose, Some Experts Say
Different kinds of masks “block virus to a different degree, but they all block the virus from getting in,” said Dr. Monica Gandhi, an infectious disease physician at the University of California, San Francisco. If any virus particles do breach these barriers, she said, the disease might still be milder.
Unfortunately our society is so litigious that governments can't advise people to wear masks for their own safety, so we have this posturing that we should wear masks to protect others. And we should. But the fabrics aren't one way materials. The non medical masks aren't perfect, but they are certainly some protection.
