Zoonosis

A zoonosis ( /ˌzoʊ.əˈnoʊsɨs/) is an infectious disease that is transmitted between species (sometimes by a vector) from animals to humans or from humans to animals (the latter is sometimes called reverse zoonosis or anthroponosis). In a systematic review of 1,415 pathogens known to infect humans, 61% were zoonotic. The emergence of a pathogen into a new host species is called disease invasion or "disease emergence".
