Moshe Hill, who to the best of my knowledge is not an expert in epidemiology, makes the bold assertion (“Take Off The Masks,” QJL 3/18) that “there is no correlation between mask wearing and better results from COVID.” He does not cite any studies. His proof is comparing, as of today, the percentage of deaths from states with mask wearing mandates and those without any mandates. There are some obvious problems with this approach. He assumes that a mandate is the same as mask-wearing and the lack of a mandate means that people are not wearing masks. He does not distinguish between the death rate before the states put in the mask mandate and the rate after they did. Also, for Hill, death is the only barometer to determine better results. It is ironic, as it is coming from someone who had COVID last year and wrote about the horrible experience. There are many people who had COVID and are still suffering long-term effects. Thus, the number of cases, as well as deaths, is the correct factor to rely upon in determining the effectiveness and necessity of masks.
