Conclusion:
The recommendation to wear surgical masks to supplement other public health measures did not reduce the SARS-CoV-2 infection rate among wearers by more than 50% in a community with modest infection rates, some degree of social distancing, and uncommon general mask use. The data were compatible with lesser degrees of self-protection.<p>If there's those more qualified I'd be interested to know if these results are only being done on the receiving end, or if surgical masks still protect others to some extent.
