What is Tinea Corporis?

Tinea corporis, otherwise known as ringworm of the body, is a common fungal skin infection caused by the spread of dermatophytes, which on humans only includes about three types: Trichophyton rubrum, Trichophyton mentagrophytes and Epidermophyton floccosum. The infection appears as a mild red bumpy rash and can spread in a circular pattern, the source of the name, to other parts of the body and is extremely contagious. It is often seen on the upper trunk, arms, and legs among children and adults.
