  2. Annals of Internal Medicine: "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"

  3. `Cochrane Library: "There is moderate certainty evidence that wearing a mask probably makes little or no difference to the outcome of laboratory‐confirmed influenza compared to not wearing a mask"

  4. "In intention-to-treat analysis, facemask use was neither effective against laboratory-confirmed vRTIs, nor against CRI, not even in per-protocol analysis."

  5. "However, overall there is a lack of substantial evidence to support claims that facemasks protect either patient or surgeon from infectious contamination."

  6. "No evidence was identified that examined a potential role for surgical face masks in protecting staff from infectious material encountered in the operating room."

  7. Southern Medical Journal: "There was no reduction in per-population daily mortality, hospital bed, ICU bed, or ventilator occupancy of COVID-19-positive patients attributable to the implementation of a mask-wearing mandate."
    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8395971/

  8. Covid advisor ""What we're worried about is people getting exposed and getting infected while thinking they were actually doing something to protect themselves,"

  9. "Making pre-school children wear masks is bad public health"
