Included in the emails is Dr. Fauci’s response to the former health and human services secretary, Sylvia Burwell, when she asked him about wearing face masks while traveling.
“Masks are really for infected people to prevent them from spreading infection to people who are not infected rather than protecting uninfected people from acquiring infection. The typical mask you buy in the drug store is not really effective in keeping out virus, which is small enough to pass through material. It might, however, provide some slight benefit in keep out gross droplets if someone coughs or sneezes on you,” Fauci wrote in a response.
