GLOSSARY: Zoonosis

Zoonosis, or Zoonose, is any infectious disease that can be transmitted (in some instances, by a vector) from non-human animals, both wild and domestic, to humans or from humans to non-human animals (the latter is sometimes called reverse zoonosis or anthroponosis). Of the 1415 pathogens known to affect humans, 61% are zoonotic. The emergence of a pathogen into a new host species is called disease invasion.
