Evidence To Empower Canadians

Hello Sonya,

As provinces lift COVID-19 public health mandates, many Canadians are asking questions about the safety of some of these changes, especially around the removal of masks, particularly in the school setting. We too are asking: is this too soon or not soon enough? We felt it was important to know: Are kids at higher risk of getting sick? Have schools been linked with super spreading? Is there specific evidence for benefit of masks in children? Could there be potential harms? We went to the emerging research to help find answers. In part 1 of this 2-part focus on these questions, here are some of the key findings that we wanted to share.

How Well do Masks Protect Us?

COVID-19 is primarily spread through respiratory droplets - including aerosols. These can easily travel around and through the various types of masks typically worn by most people.

Canadian national health agencies have recommended against general mask use (see p 227, Section 2.6. Use of Masks During a Pandemic) in the community for influenza pandemics. As the SARS-CoV-2 virus and the influenza viruses share similar characteristics and size, why would the recommendations be different? Even surgical mask producers state that their products are not designed to protect the wearer from inhaling airborne bacteria or viruses.

Multiple clinical trials have shown that wearing a mask made little or no difference to the spread of respiratory viral infections. Read more here and here.

There have been suggestions that higher quality masks (such as N95s) are effective at stopping the spread of respiratory viruses. With perfect use, these masks may reduce the spread. However, they lose their effectiveness if the mask fits improperly, becomes moist, or is removed for eating or drinking or at other times.

The Bottom Line: Overall, the evidence continues to show that masks simply do not protect against COVID-19

Do Masks Cause More Harm than Good?

Wearing masks may seem harmless, but there are risks associated with their use that may have long-term negative consequences.

Many people who wear masks for long periods report symptoms including: irritability, headaches, nausea, difficulty concentrating, and drowsiness. Some of these issues may be due to rebreathing exhaled air which has oxygen levels that are lower than, and carbon dioxide levels that are higher than, safe amounts.

Adverse effects may occur throughout the body due to altered breathing dynamics with prolonged mask wearing.

Mask wearers may be exposed to numerous particles, fibers, and chemicals that could damage the lungs and have other health consequences. Read more here and here.

Masks are ideal places for growth of and contamination by organisms that cause infections such as pneumonia, skin lesions, and sinusitis.

Dentists have coined the term “maskmouth” to describe the poorer dental hygiene thought to be due to mouth breathing while wearing a mask.

Masks hide the face and may interfere with a child’s learning, language, psychological, and social development demonstrated by reports of difficulty concentrating, less happiness, reluctance to go school, malaise, psychological impacts, and impaired learning, including speech delays. We have yet to understand the full impact of masks on the overall development of children. Read more here.

The Bottom Line: Masks are not as harmless as once thought.

Overall, Are Masks Necessary?

At CCCA, we believe that policy should always be derived from the available evidence.

The primary responsibility of all health care practitioners is ‘First do no harm’. Because of this, we respect the mantra, ‘If there is risk, there must be choice’. Clearly, this could not be any more important than when considering the welfare of all, especially children.
