Zoonotic Diseases – Zoonoses

Zoonoses is an infectious disease that affects animals and can be transmitted to humans A number of infectious diseases, including viruses, bacteria, and parasites, can be transmitted from animals to people through a variety of infection routes, including animal bites, vectors (i.e., insects), and animal-to-human contact (i.e., inhalation of respiratory droplets or skin-to-skin contact). Some examples of common zoonotic diseases include lyme disease, rabies, ringworm, and plague.

There are many zoonotic diseases, though some are more serious than others. However, all can create a serious health threat if not controlled.
