Zoonosis
Updates to Article Attributes
Body
was changed:
A zoonosis (plural: zoonoses), also known as a zoonotic disease, is an infectious disease in humans 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.
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 include:
- anthrax
- brucellosis
- COVID-19
- Ebola
- human African trypanosomiasis
- influenza
- leishmaniasis
- leptospirosis
- MERS
- rabies
- SARS
- tuberculosis
- Q fever
- zika
