We tested 14 commonly obtainable masks or masks alternate options, one patch of masks material, and a professionally match-examined N95 mask (see Fig. 2 and Table 1 for particulars).

- We systematically searched Scopus, Embase and MEDLINE for studies evaluating respiratory illness incidence after face-mask sporting .
