We asked 15 public health experts if homemade masks are a good idea to limit the spread of the coronavirus, and the results are mixed
Face masksare being touted as a way to help prevent the spread of the novel coronavirus.
- But not all experts agree that they're an effective way to keep people healthy right now.
- Business Insider surveyed more than a dozen leading

As a group of leading US scientists and doctors laid out recently in a rapid report sent to the President's office of
Still, some public health pros say, why not try it out?"The argument ... is not that it will prevent everyone from getting infected, it's that it will slow down transmission in the community a bit," Ben Cowling, a professor of epidemiology and a mask researcher at the University of Hong Kong's School of Public Health, recently told Business Insider.

"The key to managing this pandemic is staying home, staying six feet apart when outside the home for urgent business, and meticulous handwashing for 20 seconds," Friese said.But, "if you have to go to some crowded places where social distancing is unlikely, a surgical mask is better (if available), and a homemade one is better than nothing, especially for vulnerable people," Elaine Shuo Feng at the Oxford Vaccine Group said.

Robert Beardall, the lone "no" vote in the poll, is an American physician working abroad in Italy right now, and studying how the coronavirus spreads.
He worries that homemade masks will be wholly ineffective, creating a false sense of security for people who wear them. In places (like hospitals) where the air is thick with virus, he said "real antiviral masks are needed."Until a vaccine or treatment for the coronavirus is available, all the experts agree we should avoid crowded, poorly ventilated spaces, wash our hands often, and keep away from others when we feel sick.Advertisement
