I’ve completed a study of literature on the efficay of the different types of masks available to the public: Disease Transmission and Masks. One study noted that aerosol transmission is the prevalent form of infection. On this basis, face shields which I have not covered, would be the least effective form of protection due to the air leakage issue.

As usual, I am always looking for quality source material for what I write. If you have any citations, studies or data, please send them to me.

If you think this material worthwhile, please pass it on to friends.

The POOG

I started a blog in 2011 called The POOG, an acronym for "pissed off old guy". This is the current incarnation.
