Zoonosis
Updates to Article Attributes
A zoonosis (plural: zoonoses), also known as a zoonotic disease, is an infectious disease in humans (the host) for which another vertebrate animal can be the vector. Some zoonoses have an additional vector besides the vertebrate e.g. R. rickettsii is carried by ticks on mammals. Viruses, bacteria, fungi or parasites can be zoonoses.
Epidemiology
60% of cases of infectious disease are zoonotic in origin 1.
Pathology
Zoonoses may be spread through direct or indirect contact with animals. Diseases that cannot exist without humans are not considered zoonotic by all sources, and neither are some diseases that may have begun as zoonoses but are predominantly transmitted by humans (e.g. HIV).
Examples of zoonotic diseases, with causative organisms in brackets, include:
- anthrax (Bacillus anthracis)
- brucellosis (Brucella spp.)
- COVID-19 (SARS-CoV-2)
- Ebola
- human African trypanosomiasis
- influenza
- leishmaniasis
- leptospirosis
- Middle East respiratory syndrome (MERS) (MERS-CoV)
- rabies
- sudden acute respiratory syndrome (SARS) (SARS-CoV)
- tuberculosis (Mycobacteria spp.)
- tularaemia (Francisella tularensis)
- Q fever (Coxiella burnetii)
- zika
History and etymology
In Greek, the word ζώο (zoo) means animal and νοσος (nosos) means disease 2,3.
