Got some spare time? Yeah, us too.

The Centers for Disease Control and Prevention has recommended people wear some type of face mask in public as a means to slow the spread of the coronavirus.

So for those less handy among us, and for you mask skeptics, here’s what you need to know:

I thought I didn’t need a mask

Until recently, the World Health Organization and CDC were not advising that healthy people wear masks, unless you were caring for, or near someone with, a confirmed or suspected COVID-19 infection.

There were several reasons for those initial recommendations. For one, a study published last month in The Lancet noted that the limited supply of masks and other medical supplies pushed health authorities to discourage mask wearing among the general public.

The other hurdle in suggesting people wear homemade masks? No one is quite sure exactly how effective they actually are.

A 2006 study published in the peer-reviewed journal Emerging Infectious Diseases acknowledged the difficulty in determining the effectiveness of homemade masks, and suggested additional research be conducted. Further research in 2013 concluded that while homemade masks “should only be considered as a last resort to prevent droplet transmission from infected individuals,” they would likely be better than protection at all.

While wearing a mask may be an important tool against fighting the spread of COVID-19, public health experts still say it’s important to reserve supplies of medical-grade face masks and respirators for health care workers that need them amidst the current shortage of personal protective equipment.

Do homemade face masks work?

In addition to preventing the release of droplets from coughs and sneezes, homemade masks may also be effective in reminding people to stop touching their face — one of the many common ways in which the virus is transmitted.

In an , Dr. Neil Fishman, chief medical officer of the Hospital of the University of Pennsylvania, said that scientists now know that people can pass on the virus, or “shed,” about 48 hours before developing symptoms, suggesting that “masking can prevent transmission from those individuals.” interview with the New York Times , Dr. Neil Fishman, chief medical officer of the Hospital of the University of Pennsylvania, said that scientists now know that people can pass on the virus, or “shed,” about 48 hours before developing symptoms, suggesting that “masking can prevent transmission from those individuals.”

“If it’s a difference between having a mask and not having a mask, having a mask is better than not,” Dr. Jordan Sall, chief of staff at Gerber Memorial Hospital in Fremont in West Michigan, previously told Bridge Magazine.

Will wearing homemade face masks keep me from getting coronavirus?

Face masks are not a guarantee against contracting COVID-19, but can aid in reducing community spread when combined with proper mask disposal or washing, frequent hand washing and social-distancing methods as recommended by the World Health Organization.
