In a study of 143 households in Sydney, people who diligently wore surgical masks as instructed reduced their daily risk of respiratory infection by an estimated 60 to 80 percent, but fewer than half the participants kept up the demanding routinehttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC2662657/ …

Even homemade masks offer some protection and are certainly better than nothing. Studies have found that masks made from kitchen towels and cotton T-shirts are one third to one half as effective as surgical masks.pic.twitter.com/mqWl4vWYAy

Critics of universal mask-wearing argue that most people won't wear masks properly and may accidentally infect themselves. But any microbes caught in someone’s mask are microbes they would otherwise have inhaled. And direct evidence of harm from incorrect mask use is scant.

The CDC and WHO have poured considerable resources into guidelines & tutorials on proper handwashing technique. Why not do the same for masks? Always remove masks by their strings or loops, never by touching the contaminated frontpiece. Boil or wash fabric masks regularly.pic.twitter.com/eQOyYvovnE

Masks are more than physical armor—they also promote psychological resilience. They help us learn not to touch and contaminate our faces. And they can become an important social signal, an emblem of civic duty and solidarity.

Given the increasing evidence of asymptomatic spread & possible aerosol transmission of COVID-19, and the likelihood that people will be allowed to mingle again before a vaccine is ready, universal mask-wearing may soon become even more imperative.

The unfortunate truth is that we do not have nearly enough masks. And newly manufactured medical-grade masks must go to healthcare workers before anyone else. In the meantime, the best option for the rest of us is to make masks at home from tightly woven yet breathable fabric.

If you look at photos of Americans from the 1918 influenza pandemic, nearly every face is wrapped in white gauze or other fabric.

We can revive that ethic. “You must wear a mask not only to protect yourself, but your children and your neighbor,” the Red Cross implored. “The man or woman or child who will not wear a mask now is a dangerous slacker.”pic.twitter.com/ZOsYbbdQeo
