The fruit bat is believed to be the zoonotic agent responsible for the spillover of the Ebola virus. Spillover is a common event; in fact, more than two-thirds of human viruses are zoonotic . [ 4 ] [ 5 ] Most spillover events result in self-limited cases with no further human-to-human transmission, as occurs, for example, with rabies, anthrax ...
Cross-species transmission is the most significant cause of disease emergence in humans and other species. [citation needed] Wildlife zoonotic diseases of microbial origin are also the most common group of human emerging diseases, and CST between wildlife and livestock has appreciable economic impacts in agriculture by reducing livestock productivity and imposing export restrictions.

A zoonosis (/ z oʊ ˈ ɒ n ə s ɪ s, ˌ z oʊ ə ˈ n oʊ s ɪ s / ⓘ; [1] plural zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite, or prion) that can jump from a non-human vertebrate to a human.
However, there are some pathogens that do not possess this ability to spread between humans. This is the case for spillover events such as rabies. Humans infected from the bite of rabid animals do not tend to pass on the disease and so are classed as dead-end hosts. [9] An extensive list of zoonotic infections can be found at Zoonosis.
Zoonotic spillover can either result in self-limited 'dead-end' infections, in which no further human-to-human transmission occurs (as with the rabies virus), [21] or in infectious cases, in which the zoonotic pathogen is able to sustain human-to-human transmission (as with the Ebola virus). [6]
Cases of tularemia, also known as “rabbit fever," are on the rise in the U.S., according to a new report from the CDC. The report identifies symptoms and the groups most at risk.
Zoonotic diseases are complex infections residing in animals and can be transmitted to humans. The emergence of zoonotic diseases usually occurs in three stages. Initially the disease is spread through a series of spillover events between domesticated and wildlife populations living in close quarters. Diseases then spread through series of ...
The theory gained steam on Facebook, TikTok and Twitter in recent weeks, with some users reporting that their hens stopped laying eggs and speculating that common chicken feed products were the cause.
