Are masks even effective?

Homemade mask studies have shown that they are significantly less effective than surgical masks -- and they are certainly no replacement for the essential N95 respirators health care workers must wear to treat patients. "Homemade masks are partially effective," said Dr. Koushik Kasanagottu, an indoor medicine resident at Johns Hopkins Bayview center in Maryland. They offer a physical barrier from viral particles, he said, but they do not have the filters that N95 respirators do.

But they're better than nothing, especially for people that only leave publicly to form a fast trip to the grocery or pharmacy, said Anna Davies and Raina MacIntyre, public health researchers and authors of two separate studies on the effectiveness of fabric mask.
