We could actually discuss the findings and limitations of that study, but I have a feeling you don’t actually care about the actual science of it.
Before COVID, a couple of studies found that surgical masks were essentially equivalent to N95s when it comes to influenza transmission...doesn’t seem convenient for your message though.
N95 Respirators vs Medical Masks for Preventing Laboratory-Confirmed Influenza in Health Care PersonnelThis cluster randomized clinical trial compares the effect of N95 respirators vs medical masks worn by health care personnel for prevention of workplace-acquired influenza and other viral respiratory infections in geographically diverse, high-exposure outpatient settings.jamanetwork.com
Great, then why are transmission rates in mask compliant areas not dropping like rocks?
Maybe we need to start welding doors shut to keep people compliant. A leftist in my 'hood told me last week that China took care of Covid, so why could not Trump.
