Homemade masks won't protect you against COVID-19 like handwashing, distance: experts

As people across Newfoundland and Labrador work to reduce the spread of COVID-19, more of themare choosing to wear face masks while on a weekly trip to the grocery store or on their daily walk.

But with protective equipment needed in health-care facilities around the world and a shortage of masks in particular, some have taken to the sewing machine.

Erin Sonleyhas made about 300 masks at home using two different designs with three to eight layers of fabric, and says business is good.

"A lot of people in the general public have been buying them. I've been contacted by lab technicians, health-care workers, firemen, just about anybody who has to be out in public," she said.

Sense of security

Sonley sells the masks for $10 using contactless pickup or delivery, and said she has given away more masks than she has sold.

"With every $10 mask I sell, I can cover enough material to give away six or seven," said Sonley.

She stockpiledmaterial before the COVID-19 pandemic began, bought more from Fabricville before non-essential retail stores closed, but has "had to get a little bit creative" with sourcing material lately.

Sonley first started selling masks on Facebook before the social media site temporarily banned ads and listings for them on March 6.

Meanwhile, Sonely said she simply feels more comfortable in public places when a mask is covering her mouth and nose, particularly since this province's first case of community transmission of the virus.

Little evidence on homemade

Donna Moralejo, a professor in Memorial University's faculty of nursingwho specializes in infection control, says masks can prevent the spread of COVID-19 by stopping droplets from an infected person's cough or sneezefrom landing on your eyes, nose or mouth.

When it comes to homemade masks,Moralejo saidthere is little scientific evidence about their effectiveness.

"I could only find two studies, and they were several years old, and they were done in the laboratory to see how well homemade masks were able to filter out different sizes of particles," said Moralejo.

While she said homemade masks fared better than expected in the studies, they are not as effective as surgical masks or N-95 masks.

"If there's nothing else, they are absolutely better than nothing," Moralejo said.

The World Health Organization has created a website with advice for the public about when and how to wear masks.

Chief medical officer of healthDr. Janice Fitzgerald said Wednesday thatmedical grade masks are the only ones certified to prevent the spread of viruses.

But nothing replacescareful handwashing and physical distancing.

And Moralejo notes it's important to be careful when using any mask.

"I'd be very concerned about people touching the front of the mask, which would be contaminated, and then touching their eyes or their nose or their mouth."
