Hi, lead author of the study here. That's not really what we had in mind. Masks do block aerosols (proven) & if you read our paper carefully, you'd notice our results actually support the calls for universal masking, as well as N95, FFP3 or equivalent. Take care, @DrEliDavid! https://t.co/FKxzFflKgB
