First, consider how the debate has evolved and the underlying scientific evidence. Several randomized trials of community or household masking have been completed. Most have shown that wearing a mask has little or no effect on respiratory virus transmission, according to a review published earlier this year in Emerging Infectious Diseases, the Centers for Disease Control and Prevention's journal. In March, when Anthony Fauci said, "wearing a mask might make people feel a little bit better" but "it's not providing the perfect protection that people think it is," his statement reflected scientific consensus, and was consistent with the World Health Organization's guidance.
