Note that Bubonic Plague killed a third of Europe and was principally spread by fleas. However, the really scary and highly contagious variant was Pneumonic Plague. It spread easily and killed quickly. The bad diseases are at their worst when they go airborne.
A flea or mosquito bites an ebola patient. It then bites a previously uninfected human. Now we have a host issue.....
Your tagline... funniest stuff ever. Especially like the Penguin episode.
Read The Return of the Black Death by Susan Scott and Christopher Duncan and you'll change your mind about rats and fleas causing the European plague of 1347 to 1666. It was airborne.
There’s an interesting case to be made for the Black Death being hemorrhagic fever, similar to Ebola and Marburg.
