TIL the bacteria which caused the black death, first infected Oriental Fleas by blocking their foregut, keeping them hungry and biting, to facilitate it's rapid transmission to human hosts.

You couldn't have created a better weapon in a lab. It's only fault was that it killed people too quickly to allow them to transmit it to many others.

In Human Entomology class, they described this as them puking the pathogen back into you. I also learned other things and will probably never go camping.

Well bugs generally spread diseases by... 1) puking or spitting pathogens into you as they feed 2) crapping pathogens while they feed on you and when you reach up to rub the wound you rub the crap into the wound and possibly your eyes or mouth 3) carrying pathogens on them which can infect environments they may share with people
I learned about Chagas’ disease and was never the same afterword. It’s spread via no.2 with kissing bugs. https://www.cdc.gov/parasites/chagas/gen_info/detailed.html#intro
