Zoonotic Diseases
Bayani Gaba-gaba
Some diseases do not stay inside the species they start in. A sick goat can pass its illness to the farmer who milks it; a dog with rabies can pass its infection to the child it bites; a cow with tuberculosis can pass the bacteria to the family that drinks its unboiled milk. Diseases that cross this way, from animal to human, are called zoonotic diseases, and they turn animal health from a farm concern into a public health one.
In this lesson you will learn what makes a disease zoonotic, meet the zoonoses that matter most on Nigerian farms, trace the specific routes by which each one reaches a human host, and learn the everyday precautions that close those routes. You will also see why this topic reaches far beyond the farm gate, to abattoir workers, veterinarians and the general public who never touch a live animal at all.
