Are You at Risk for Ringworm?

Ringworm is a skin infection caused by a fungus—not a worm—and causes flat, ring-shaped patches to develop that have a raised scaly border.

Ringworm can be very itchy and can grow slowly, increasing in size and covering more areas of the body.

Ringworm risks can include:

  • Spending time in hot, humid weather
  • Having contact with an infected pet
  • Sharing personal belongings (towels, clothes, razors and other things without disinfecting or washing them)
  • Wearing clothing that chafes the skin
  • Using a locker room or pool without washing and drying your feet before putting on your socks and shoes

Ringworm is very contagious—if you notice any signs or symptoms you should see a dermatologist immediately, keep the infected area clean and dry and avoid sharing personal belongings. Wash your hands immediately after touching the infected area.
