> Masks can't be sealed and all the studies that say they are somewhat effective use mannequins with perfect seals. That's not true. Here is a lit review that shows you multiple avenues of evidence that show masks are effective: http://files.fast.ai/papers/masks_lit_review.pdf http://files.fast.ai/papers/masks_lit_review.pdf > Real world data from Florida shows schools with and without mandates had the same rates of infection which mirrored the general communities. Again, mask wearing is effective. Mask mandates may not be. There is a difference, and the difference is compliance. If people don't actually wear masks, that's not evidence that masks don't work. http://files.fast.ai/papers/masks_lit_review.pdf http://files.fast.ai/papers/masks_lit_review.pdf
