What term refers to diseases transmitted from animals or insects to humans?

The term that accurately describes diseases transmitted from animals or insects to humans is "Zoonotic Disease." This term encompasses a range of infectious diseases that can be transmitted through various routes, such as direct contact with animals, bites from insects, or exposure to environments where infected animals reside.

Zoonotic diseases are particularly significant because they can bridge the gap between wildlife and human populations, often leading to outbreaks when environmental or ecological factors change. Classic examples include rabies, Lyme disease, and various forms of influenza that originate from animal reservoirs. Understanding zoonotic diseases is crucial for public health and infectious disease management, especially in the context of veterinary and human health interactions.

In contrast, the other terms listed do not pertain to the transmission of diseases from animals or insects to humans. "Biological Transmission" refers more broadly to the process whereby a pathogen is transmitted by an organism, often without specifying whether it originates from animals; "Venereal Disease" specifically relates to sexually transmitted infections, and "Appendicitis" is a condition involving inflammation of the appendix and is not infectious in nature nor related to animal transmission.
