See if you can find PPE reports from the Ebola days; up to 90% mortality meant that healthcare teams had to be absolutely protected. Before exposure, many teams underwent training refreshers involving fluorescing powder to check their PPE. Often, participants were surprised/dismayed to find fluorescence under masks or on skin within minutes, so that in some cases it took days before team/s could confidently gear up and be sure that they're not risking exposure.

This sort of rigor isn't seen for C19 with its fraction of a percent mortality and aerosol rather than body fluid spread, but it's interesting when out and about to watch how often people touch/adjust masks, whether cloth or paper, or pull masks out of pockets for reuse. Even disposable paper masks are being reused for convenience. IMHO there really needed to be a public "use it properly!" campaign rather than just "wear a mask, any mask will do."

Interestingly, it looks as if Tony Fauci is wearing disposable surgical masks under his cloth masks and POTUS also seems to have something else under his mask. Fauci did try to recommend double masking at one stage but it's since gone mostly back to masking exhortation or mandate.
