After studying the origins and actions of several prominent Canadian anti-maskers, we can now offer you the definitive primer to becoming a conspiracy-baiting, immensely annoying influencer.

During the COVID-19 pandemic, masks were widely promoted and mandated as a key measure to help reduce the transmission of SARS-CoV-2. These policies were primarily informed by laboratory evidence demonstrating the effectiveness of particle ...

Based on the status of the COVID-19 global pandemic, there is an urgent need to systematically evaluate the effectiveness of wearing masks to protect …

Randomized controlled trials are considered the gold standard when assessing the effectiveness of an intervention. However, this type of study can vary greatly in quality, particularly in complex interventions such as face masks, affecting the reliability of the results. In this context, many scientists consider that randomized controlled trials should…

None.

Experts said a Cochrane review study seemed to imply masks don't work against COVID spread, but it was misinterpreted and was actually looking at mask interventions.

People online are touting the results of a Cochrane review to incorrectly claim that it shows masks “don’t work” against the coronavirus. But the primary conclusion of the review is that it’s uncertain from randomized controlled trials whether mask interventions in the community help slow the spread of respiratory illnesses.

A new study indicates that face masks did not significantly lower Covid-19 infection risk after the initial Omicron wave, highlighting the need for adaptable strategies and further research as risk factors evolve. New findings from the University of East Anglia suggest that wearing face masks did n

This rapid systematic review of evidence asks whether (i) wearing a face mask, (ii) one type of mask over another and (iii) mandatory mask policies can reduce the transmission of SARS-CoV-2 infection, either in community-based or healthcare ...

Coronavirus skeptics are claiming a large-scale review of public health interventions proves that masks are useless against Covid-19. This is misleading; the Cochrane Library's editor-in-chief said these interpretations of the analysis are "inaccurate," and medical experts say other research shows face coverings offer some individual protection.

A new scientific review of the efficacy of masks is deeply flawed. That hasn’t stopped some from touting it

A review of Canada's current post-mandate status, evidence supporting temporary and targeted mask mandates, and critical success factors.

In 2020, with adult ICUs at risk of being overwhelmed, we wore masks and accepted restrictions. Now pediatric intensive care is at risk. Will leaders follow the evidence and tell us to mask up?

The science around the use of masks by the public to impede COVID-19 transmission is advancing rapidly. In this narrative review, we develop an ana...

Objective To evaluate the personal protective effects of wearing versus not wearing surgical face masks in public spaces on self-reported respiratory symptoms over a 14 day period. Design Pragmatic randomised superiority trial. Setting Norway. Participants 4647 adults aged ≥18 years: 2371 were assigned to the intervention arm and 2276 to the control arm. Interventions Participants in the intervention arm were assigned to wear a surgical face mask in public spaces (eg, shopping centres, streets, public transport) over a 14 day period (mask wearing at home or work was not mentioned). Participants in the control arm were assigned to not wear a surgical face mask in public places. Main outcome measures The primary outcome was self-reported respiratory symptoms consistent with a respiratory infection. Secondary outcomes included self-reported and registered covid-19 infection. Results Between 10 February 2023 and 27 April 2023, 4647 participants were randomised of whom 4575 (2788 women (60.9%); mean age 51.0 (standard deviation 15.0) years) were included in the intention-to-treat analysis: 2313 (50.6%) in the intervention arm and 2262 (49.4%) in the control arm. 163 events (8.9%) of self-reported symptoms consistent with respiratory infection were reported in the intervention arm and 239 (12.2%) in the control arm. The marginal odds ratio was 0.71 (95% confidence interval (CI) 0.58 to 0.87; P=0.001) favouring the face mask intervention. The absolute risk difference was −3.2% (95% CI −5.2% to −1.3%; P

Stricter Covid mask rules could’ve saved hundreds of thousands of lives, new study finds - Restrictions in Northeastern states likely ‘saved many lives’ say researchers

Could masks create a comeback as we move beyond COVID-19? Here are the latest insights into their impact and effectiveness on public health.

This attempt to discredit a central piece of protective gear used around the globe fails to account for several fundamental scientific principles.

The Cochrane Library, a trusted source of health information, misled the public by prioritizing rigor over reality

Researchers surveyed more than 1,500 adults in Brazil about their personalities and how well they adhered to Covid-19 prevention measures. Their findings point to a few psychological reasons why some people don't wear face masks, maintain social distance and practice hand hygiene.

Calgary physician organizer Dr. Amy Tan explains how to clean your mask, which kind to choose and why wearing one is absolutely vital.

Now we have definitive proof that masks really are effective.

Results from EGC affiliate Mushfiq Mobarak and coauthors’ recent paper clearly demonstrate that mask usage reduces Covid-19, highlighting how masks should continue to play a vital role in fighting the pandemic.

As the masks come off at my daughter’s school — and around the country — I’m worried about COVID’s next move.
