The conclusions were "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."
Despite the limitations of this study, do you agree that wearing masks will not significantly reduce the risk of SARS-CoV-2 acquisition in "outside the home" setting?
