A major study published by the Annals of Internal Medicine last week found no statistically significant difference in COVID-19 cases between mask-wearers and non-mask-wearers.
Dr. Christine Laine is the editor-in-chief of Annals of Internal Medicine. She chose to take the study on because it was “the only randomized control trial of masks for SARS-CoV-2 infection that has been done to date” and answered the specific question of whether or not masks protect wearers in areas with low infection rates and high levels of physical distancing.
