Funny that, because I can find references to likely aerosol transmission and the assumption that cloth masks would reduce aerosol transmission to a small degree in the early 2020 minutes of the body that later recommended mask mandates (on the basis reducing stuff to a small degree is important when reducing pandemic spread...) in my country https://assets.publishing.service.gov.uk/government/uploads/... Not all aerosol particles are the same size, and particles don't have to be smaller than holes they pass through for a grid of fibre to obstruct a significant proportion of them. The change in guidance wasn't a conclusion masks were a panacea, they were a reflection that even a small degree of protection was better than no protection in a situation where existing measures weren't slowing its spread fast enough. The people who were against masking on principle by and large didn't care what degree it reduced it by, because they just didn't want to be told to wear masks. |
