Lincoln Ave. By Kimberly Meenen Information Specialist University of Illinois College of Veterinary Medicine Ringworm or dermatophytosis is an infection of the hair and hair follicles caused by certain types of fungi. These fungi can affect many species of animals and also humans. Animals can spread most types of ringworm to humans.
Ringworm is the most common zoonotic disease transferred from animals to humans.
Studies show that the rate of infection is increasing. If your pet develops a suspicious skin lesion, consult your veterinarian. Minimize your contact with the animal until the problem can be diagnosed. Good hygiene is extremely important. Wash thoroughly after handling your pet.
