There is evidence that syphillis came from the Americas. There is evidence it was introduced to the Americas by Europeans. One problem is that it's hard to distinguish teritiary syphillis from tuberculosis or leprosy on bones.
As for Borreliosis, there are many variants of it endemic to Europe and spread by ticks. No evidence that it came from the Americas.
Neither of those spirochetes are zoonotic.
- vanattab 5y agoWhy is a tic biting a human and transferring Borreliosis not considered zoonotic?
- hoseja 5y agoI agree, Lyme disease definitely isn't primarily human.
- littlestymaar 5y agoMy understanding is that if the tick was only a vector between two humans (for instance, malaria isn't a zoonosis, because the mosquito is just transmitting the disease between humans), then it would not be a zoonosis. But in most cases with Lyme disease, the tick is actually transmitting the disease from another animal to a human, therefore it is indeed a zoonosis.[1] [1]: https://en.wikipedia.org/wiki/Lyme_disease#Transmission https://en.wikipedia.org/wiki/Lyme_disease#Transmission
- lostlogin 5y agoAccording to everyone favourite source, Lyme disease is zoonotic. I had never heard the term until today, so take the claim with a pinch. https://en.m.wikipedia.org/wiki/Zoonosis https://en.m.wikipedia.org/wiki/Zoonosis
