The more important aspect is that very few people have been or are doing this- changing them every hour which is the recommended frequency to be effective. I am referencing individuals in congested areas- airports for instance could have short term benefit of blocking particles x size and greater, but germs cling onto cotton masks. Anytime a person touches a surface that has just been touched by a person with a cold virus and that person adjusts his or her mask, guess where the germs are now? On the mask until effective cleaning or disposing quickly to reduce odds of infection. Masks don’t work because of the size of the pores in the masks, the size of the smaller type of viral molecules that break down and primarily because we’re humans! We are not made to wear masks since they’re quite uncomfortable and we adjust them constantly!
Around the end of last flu season, it was reported that 2 entire strains of flu viruses were “wiped out” last year, and before learning otherwise, I assumed that masking and social distancing were the causal factors to that outcome. After learning that hospitals and nursing homes were counting deaths as Covid deaths when in fact they were due to some other cause, and by doing so they were given federal monies, the facts threw out the idea that these 2 strains of flu had been somehow wiped out. So, any way it pans out lies were in the mix to support the covid narrative.
