Concept
Zoonosis
Infection transmitted from animals to humans
zoh-oh-NOH-sis
High-yield clue
A zoonosis is any infection whose reservoir is an animal, transmitted to humans directly or via a vector.
Overview
A zoonosis is an infectious disease that spreads naturally from vertebrate animals to humans, with the animal serving as a reservoir. The concept frames many high-yield organisms by their animal source.
Classification
- Public-health concept
- Animal-reservoir transmission
- Direct or vector-borne routes
Lab & identification clues
- Reservoir is the animal host that maintains the pathogen
- Vectors (ticks, fleas, mosquitoes) can bridge animal to human
- Spillover events introduce animal pathogens to people
Associations
- Rabies, brucellosis, and tularemia as zoonotic examples
- Occupational and food/water exposure vocabulary
- Overlaps with vector-borne and foodborne framing
Commonly confused with
- Zoonosis vs vector-borne disease
- Reservoir vs vector
