What type of disease is categorized as "zoonotic"?

A zoonotic disease is explicitly defined as an illness that is transmittable from animals to humans. This category of diseases can arise from various sources, including viruses, bacteria, parasites, and fungi, and can be spread through direct contact with animals, bites, or consumption of contaminated food products. Examples of zoonotic diseases include rabies, West Nile virus, and salmonellosis.

The other options describe different kinds of diseases but do not accurately capture the essence of zoonotic diseases. Options that refer to human factors or specify diseases affecting only humans or domestic animals fail to encompass the fundamental characteristic of zoonotic diseases, which is their transmission potential from animals to humans. This distinction is critical in understanding disease spread, prevention, and control measures in public health.
