What are zoonoses?

Zoonoses refer specifically to diseases that can be transmitted from lower animals to humans. This definition encompasses a wide range of infectious diseases that originate in animals and can subsequently infect human populations. Examples of zoonoses include rabies, Lyme disease, and salmonella. The significance of understanding zoonoses lies in their capacity to potentially cause outbreaks in human populations, highlighting the importance of managing animal health and monitoring for diseases that can cross the species barrier.

The other options mischaracterize zoonoses by limiting their scope or misdefining their origin; for instance, diseases exclusive to humans or wild animals do not qualify as zoonoses, nor do diseases solely transmitted through the food chain. Understanding zoonoses is crucial for public health, veterinary medicine, and environmental health, as controlling and preventing these diseases often requires a multi-disciplinary approach that considers both human and animal health.
