Masks definitely reduce the number of droplets emitted by the wearer. I'm concerned, however, about the actual number of viral particles released rather than just droplets. When those droplets intercept the mask they attach to the mask's material and dry out; the particles may not remain adhered, but may be blown loose by exhalations. The viruses have been proven to be much longer lived than the droplets which carry them.

I bounced that observation off a friend of mine who is an MD specializing in microbiology, and is involved in the New Zealand COVID efforts. "It’s all about risk reduction. (not prevention) Obviously best to clean the mask after being present in confined spaces. Soapy water will disrupt the lipid virus envelope."
