Health-care workers need masks to protect themselves when they treat people with COVID-19 and other contagious diseases. But there’s a shortage of masks, especially N95 masks which provide a higher level of protection, because of the COVID-19 outbreak.
Masks have been sold out for weeks in retail stores; hospitals, especially in the U.S., are saying their supplies are rapidly dwindling and orders for more masks are only being partially fulfilled if at all.
Is it proper, then, for healthy people who are not caregivers to be wearing masks?
Many medical officials in Canada and U.S. have been saying that it’s not necessary for healthy people to wear masks. It’s more effective to keep your hands clean by washing with soap and water, don’t touch your face with unwashed hands, maintain a distance from other people, and get enough sleep. People who are sick, who are coughing and sneezing, should wear a mask. So should health-care workers when they are treating contagious patients.
The U.S. surgeon general, in a Twitter message, said: “Seriously people — STOP BUYING MASKS! They are NOT effective in preventing general public from catching #Coronavirus, but if healthcare providers can’t get them to care for sick patients, it puts them and our communities at risk!”

It’s a confusing message. The masks are not effective for healthy people, yet they are essential for health-care workers.
The nuance seems to be this. Healthy people, who are not surrounded by sick people, have little to gain by wearing a mask. Leave the masks for the people who really need them — health-care workers who are surrounded by sick people. We need to make sure there are plenty of masks for doctors and nurses to help them stay healthy so that they can look after us if we get sick.
B.C. provincial health officer Dr. Bonnie Henry was asked about the mask issue and offered this reply:
“In terms of us all wearing masks, one it’s a colossal waste of masks and we know that people who aren’t ill and are wearing a mask often fiddle with their face and that can be a risk for them self-inoculating and becoming ill. … We need to keep the masks for where they’re needed. And I do recognize it is an expectation and symbol of respect in some societies that you wear a mask when you’re out to protect others. And I respect that … but I don’t think it’s necessary, and I will continue to say it’s not necessary, unless you’re sick yourself.”
But her message is not being embraced in some quarters.
A small Vancouver grocer, for example, posted a sign saying only people wearing a mask would be allowed into the store.
The World Health Organization has videos showing how to wear a mask properly. You can find it here.
Here’s a summary of the advice:
• Healthy people only need to wear a mask if they’re taking care of someone who is sick.
• Wear a mask if you’re coughing and sneezing.
• Mask-wearing is only effective if you also clean your hands frequently with soap and water or an alcohol-based hand sanitizer.
• Make sure your hands are clean before putting on a mask.
• The mask needs to cover your mouth and nose; there should be no gaps between mask and face.
• Don’t touch the mask while you’re wearing it.
• When removing the mask, don’t touch the front; remove it from behind.
• Dispose of the mask in a covered bin; wash your hands.
N95 masks are designed to be used just once. But because of the mask shortage, some hospitals are experimenting with ways to decontaminate masks so that they can be used multiple times.
Much of the mask supply comes from China. Because of the COVID-19 outbreak there, many mask factories were closed until recently, and China has restricted the export of masks so that its own needs can be met.
Mask manufacturing is being stepped up in other parts of the world, including on Vancouver Island. A clothing-manufacturing company here, Salts and West, is making reusable cloth masks, which aren’t as effective as an N95, but can be used if there are no other options. They can also be combined with an N95 to extend the life of that mask.
