Answer:
Variables in fabrics, fit, and user behavior can influence how well a mask might block the virus’s spread
With cases of COVID-19 growing rapidly in the US and mounting evidence that the virus responsible, SARS-CoV-2, can be spread by infected people before they develop symptoms, the US Centers for Disease Control and Prevention recommended on April 3 that people wear cloth face coverings in public places. This guidance is a shift from the center’s previous position that healthy people only needed to wear masks when caring for someone who is sick. The recommendation also follows recent calls by experts on social media and other platforms for the general public to don nonmedical, cloth masks to help reduce the transmission of the novel coronavirus.
“Members of the general public should wear nonmedical fabric face masks when going out in public in one additional societal effort to slow the spread of the virus down,” Tom Inglesby, director of the Johns Hopkins Center for Health Security, tweeted on March 29.

These experts hope the measure will reduce the rate of disease transmission by adding an additional layer of protection in places where social distancing is difficult, such as grocery stores, while reserving limited supplies of medical-grade protective equipment for health-care workers.
The internet is exploding with mask-sewing patterns and advice on which materials are best to use, but many unanswered questions remain about how exactly SARS-CoV-2 spreads and what benefit widespread wearing of nonmedical masks may offer individuals and the public. Because of the inherent variability in household materials, mask design, and mask-wearing behavior, experts caution that the practice is no replacement for social distancing.
