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 ...
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.
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.

Epidemics caused by zoonotic diseases ... we would expect the analysed pathogens to cause four times the number of spillover events and 12 times the number of deaths in 2050 than in 2020,” they ...
SARS-CoV-2, the causative agent of COVID-19, was first introduced to humans through zoonosis (transmission of a pathogen to a human from an animal), and a zoonotic spillover event is the origin of SARS-CoV-2 that is considered most plausible by the scientific community.
Animal-to-human spillover events. When humans have become infected with bird flu, it’s almost always been through contact with infected animals. All but one of these so-called spillover ...
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 spillover. Human-Rodent Interactions: Changes in land use, such as deforestation, agricultural expansion, and urbanization, increase human contact with rodent habitats, amplifying exposure risk. Occupational and recreational activities in rural areas also heighten exposure risks.
