Diseases that can be transmitted between humans and animals include groups of bacteria, viruses, fungi, and parasites, each of which causes different symptoms, so that sometimes due to the severity of the symptoms and the delay in referral, we see human deaths following these diseases.

Humans contract animal-borne diseases through direct contact with animals, the consumption of livestock products, the slaughter of livestock in unhealthy environments, and the sharing of habitats.


Rabies is a common disease between humans and dogs and canines that affected 9 people in the country last year.
