According to Gaughan, animals can pass many diseases and illnesses to humans. There are many diseases that humans can get from their pets, and a few can be problematic. This disease is transmitted by saliva, and it can be fatal if left untreated. Fortunately, it is 100 percent preventable with a vaccine. Another problem is ringworm.
Ringworm is actually a fungal infection called dermatophytosis.
Humans can get the disease by contact with infected animals. In humans, ringworm may cause dry itchy patches on the skin. Roundworms and hookworms are big problems, too. In animals, these worms are intestinal parasites. Humans can get the disease by ingesting the infectious eggs found in the feces of an infected pet.
