Double-masking — specifically, wearing a surgical mask underneath a cloth mask — may provide an extremely high level of protection against the viral particles that cause Covid-19, the Centers for Disease Control and Prevention reported Wednesday.
A year into the pandemic, the report is the first from the CDC that breaks down how well certain mask-wearing techniques allegedly work to protect wearers and those around them.
“We know that masks work,” said Dr. John Brooks, a medical epidemiologist at the CDC and co-author of the new report. “This is about how to help them work better.”
Uh, no, I’ll pthanks for the guidance.
The claim is geometrically impossible, it is like using 2 chain link fences to block flies. They are liars.
