Let me say this upfront — I am most definitely an advocate of mask wearing to prevent the spread of COVID-19.
Having said that, I want to share an article I recently came across that questions the efficacy of masks. In the article discussion, there was a reference to a study done by a medical student and two medical school professors at the Cato Institute.* In this study, the authors asked …
So, are masking requirements just “public health theater,” providing baseless assurance to a fearful public? Or has new evidence emerged to confirm the belief that masks—or, at least, the cloth masks that are commonly used—reduce respiratory virus transmission?
I think it might be worth your time to read both the article (The Ambiguous Science on Masks), as well as the referenced study: How Effective Are Cloth Face Masks? (The latter includes “a summary of the scientific literature on the effectiveness of masking, both against respiratory infection generally and against COVID-19.“)
PLEASE NOTE: This post is not a vote for or against wearing masks by the general public to prevent the spread of COVID-19. The information is simply being shared as something to think about … and debate, if you so desire.
