Interesting that politics is a vector for contagion.

When you think about politics is very contagious, politicians infect activists, who infect regular folk that advocate for stuff they don't benefit from, when elections come near, it's flu season.

Double parasite burgers where a new parasite leeches of an existing vector are common in biology as well. Like malaria and mosquitoes.

Philosophically fun, sure, but the article also points out that another vector was "Your language settings have been changed to Spanish", so I don't know if it's as profound as you're making it out to be. Anything that makes us panic can be a vector.
