Zoonoses (Animal-related diseases)
A zoonosis or zoonotic disease is one that normally exists in animals, but can infect humans. Human illness from a zoonotic disease agent is often accidental. People can become infected through contact with infected livestock, game animals, and pets. Also, some zoonotic diseases are transmitted to humans through tick and mosquito bites.
