Hidden benefit: Facemasks may reduce severity | EurekAlert!

“If the variolation effect is strong, then the number of severe cases, and consequently pressure on health-care systems, could be substantially reduced if most people wear masks –– even if masks don’t prevent them from being infected,” says senior author David Earn, Faculty of Science Research Chair in Mathematical Epidemiology and Professor of Mathematics at McMaster and Canada’s Global Nexus for Pandemics & Biological Threats.

The model suggests effective masking could drastically slow the spread of COVID-19, reduce the magnitude of the pandemic peak by “flattening the curve,” and reduce the prevalence of severe cases from that point forward.
