About that "study" on masks in the fringe speculative journal Medical Hypotheses...besides its being utter BS, its author Baruch Vainshelboim doesn't even work for @Stanford or the Palo Alto VA! https://apnews.com/article/fact-checking-629043235973 …

There are plenty of RCT studies showing cloth masks result in higher rates of infection than the control groups. The studies consistently show that only N95 respirator masks result in lower infection rates. From 2015:https://pubmed.ncbi.nlm.nih.gov/25903751/

I've read the study. That study had no true control with no masks. The "usual practice arm" used surgical masks much of the time. All that study shows is that cloth masks don't work as well as surgical masks; it does not show that masks don't work.
