What is the common name for tinea pedis?

Tinea pedis is commonly known as athlete's foot. This infection is caused by a fungal organism and typically affects the skin of the feet, leading to itching, redness, and a burning sensation. The term "athlete's foot" originates from the condition's prevalence among athletes, likely due to the moist environments created by sweaty feet and the sharing of communal spaces like locker rooms.

Other options refer to different conditions. Ringworm is a fungal infection that can affect various body parts but is not specific to the feet. Jock itch is another type of fungal infection that typically occurs in the groin area. Psoriasis is a chronic skin condition that leads to rapid skin cell production, resulting in scaling and inflammation, and is unrelated to fungal infections. Understanding these distinctions helps to clarify why athlete's foot is the accepted common name for tinea pedis.
