Els I want a disease 🥺
You get Glanders! Glanders is a disease caused by the bacteria Burkholderia mallei. It is a zoonotic (an animal disease that can be transmitted to people. the reverse, human disease transmitted to animals is called anthroponosis) infection that primarily infects horses, mules, and donkeys (i DON'T know if it infects zebras, id have to do digging) and is transmitted through direct contact with infected animals. In both animals and humans it causes respiratory infections and massive abscesses. Fatality rates are high and the amount of bacteria needed to establish infection is relatively low, AND because it has allegedly been used in the past as such is technically listed as a potential bioweapon agent, but there's no vaccine which makes this unlikely.
It HAS been eradicated from most of the world but it still exists in some places. Horses entering the US are screened to prevent establishing infections
