I’ll be honest, I don’t really follow your argument. If they are partially effective, it helps reduce the R value, which prevents transmission on a population level. If it is partially effective with those with a high level of viral shedding, I don’t see why it would be less effective for those with lower viral loads. It seems reasonable to assume that masks will help to reduce transmission, until further robust evidence shows they don’t. I mean what is the alternative? Additionally, interesting article suggests that salt infused masks have increased efficacy against viral particles. Perhaps using salt infused masks would be even better? https://www.nature.com/articles/srep39956 https://www.nature.com/articles/srep39956
