That's a very cool visualization and I wish I'd seen it before. I am curious though as to what makes some viruses have higher R values than others. These masks more effectively stopped influenza and I still don't understand why.

Google cross-protection and competition in respiratory viruses. Lots of pre-2019 literature.
