Zoonoses Are Diseases That Jump From Animals to Humans

A zoonosis is an infectious disease that can be transmitted from other animals to humans.
They are common: more than 60% of human infectious diseases are zoonotic.
They start in wild or domesticated animals and cross into humans.

Definition

Zoonoses

Zoonoses are infectious diseases that are naturally transmitted between animals and humans.

How Zoonoses Cross Into Humans

Direct contact with an infected animal or its fluids, such as saliva or blood.
Indirect contact with a contaminated environment, such as soil or water.
Vector-borne transmission through the bite of an insect such as a mosquito or tick.
Foodborne transmission from eating or drinking contaminated food or water.

Analogy

Think of a pathogen as a traveller looking for a new host to invade.
Close contact between animals and people opens a bridge it can cross.
