Jane Orient, M.D. explains that there is probably a simple explanation for the rise in cases after mask mandates, but universal mask mandates do present some risks.  Orient explains the concern about sick people re-infecting themselves while wearing a mask, how masks are causing headaches and perhaps fatal consequences for individuals engaged in strenuous physical activity.  Orient talks about the benefits of fresh air and how it was used to help recovering patients in the 1918 flu pandemic.  And last but not least, what seems to be driving “mask mania.”
