Germs and Infections You Could Catch at the Gym

Ringworm (tinea corporis)

What It Is: A common infection of the skin caused by a variety of fungi. You can catch it from skin-to-skin contact, dirty towels, wet gym shower floors, and other infected surfaces, says Dr. Radusky.Symptoms: Look for a raised red patch of skin with scale along the periphery. Common areas for ringworm to show up include the chest, back, buttocks, and thighs—but in reality, the rash can be anywhere on your body.
