Ted Noel:
“…I wore surgical masks daily for 36 years as an anesthesiologist. Their purpose was to reduce the chance that I would infect an open wound with bacteria from my mouth. This article of faith has been shown to be false. If staff who are working outside of the immediate sterile field do not wear masks, there is no increase in wound infections. And this is in a closed environment where staff will be present for hours. This casts a very large cloud of doubt on the utility of masks for COVID-19.
Another problem arises when we look at the use of masks by the public. Even accepting the uncertain premise that masks are useful, “incorrect use and disposal may actually increase the risk of pathogen transmission, rather than reduce it, especially when masks are used by non-professionals such as the lay public.” Given that most “masks” are simply kept handy for use when required, set aside, and then re-used, most mask-wearing by the public is likely to increase virus exposure, not reduce it.
But do properly used surgical masks reduce disease spread in the general public? To say there are almost no data would not be overstating the case. When households with sick kids were examined, even rigorous mask-wearing provided no statistically significant improvement in adult infections.
Let’s put that in plain English. Even if you did everything to protect yourself with surgical masks, even keeping it on when your kid wants to see your face, it might reduce your chance of getting sick, but we can’t prove it. And that’s in a well designed study intended to get a meaningful result. “[H]ousehold use of face masks is associated with low adherence and is ineffective for controlling seasonal respiratory disease” (emphasis added)…”
