Analysis Examines Mask Usage in Canada
In an analysis on the use of masks by the general public during COVID-19, the Toronto Star cited an analysis published by SPH's Margaret Sietsema, PhD '15, MS '11, assistant professor of environmental and occupational health sciences, and Lisa Brosseau, PhD, a retired professor of environmental and occupational health sciences.
While their analysis recommended against the widespread use of masks, Sietsema noted there is a high level of divergence of opinion on this subject. “There’s a debate amongst all the experts,” she said. “Who knows what’s going on?”
Leaving aside the fact that they are ineffective, telling the public to wear cloth or surgical masks could be interpreted by some to mean that people are safe to stop isolating at home. It’s too late now for anything but stopping as much person-to-person interaction as possible.Environmental and Occupational Health Sciences|
