Is Ringworm in Cats Contagious to Humans?

Ringworm is the most common skin infection in cats. It is contagious to humans. Recognizing the symptoms is critical to preventing the transmission of the infection from cat to human.

  1. What is Ringworm?

    • Ringworm is a fungal skin infection. Parasitic organisms known as dermatophytes cause ringworm by invading dead layers of skin and hair. Cats can get ringworm from infected animals or from a contaminated environment.

    Common Carriers

    • Up to 20 percent of cats are asymptomatic carriers of microsporum canis, the most common form of feline ringworm. Ringworm is common in kittens and cats with FIV. Longhaired cats and cats under stress are also more likely to have ringworm.

    Symptoms

    • Infected cats will have circular bald spots, usually on the head and limbs, accompanied by redness, itching, dandruff, flaky skin and claw infection.

    Warning

    • Ringworm in cats is highly contagious to humans. According to the University of Illinois College of Veterinary Medicine, at least one member in 30 to 70 percent of households with an infected cat will become infected.

    Treatment

    • If you get ringworm from an infected cat, you can apply anti-fungal cream twice a day. If this does not work, a doctor can prescribe oral medication.
