The U.S. Centers for Disease Control and Prevention has advised all Americans to wear a face mask in public settings where it's difficult to maintain two metres of social distancing.
That includes grocery stores and pharmacies. According to the CDC, it's particularly important to wear masks in "areas of significant community-based transmission".
"CDC is additionally advising the use of simple cloth face coverings to slow the spread of the virus and help people who may have the virus and do not know it from transmitting it to others," the website states. "Cloth face coverings fashioned from household items or made at home from common materials at low cost can be used as an additional, voluntary public health measure."
This come in the wake of growing public awareness that covering one's nose and mouth has the potential to reduce the rate of infection of COVID-19 so long as everyone is also practising social distancing and frequent handwashing.
The scientific journal Nature has posted an early version of a manuscript, which suggests that the disease can be spread by people who are still asymptomatic.
So how do you make a face mask at home? The video below shows three DIY versions—one with a paper towel, one with a T-shirt, and one with a bandana.
None of them require any sewing.
