Ringworm is a common fungal infection that affects the skin, hair, and nails. Despite its name, it is not caused by a worm but by a group of fungi called dermatophytes. The infection appears as a red, circular rash with raised edges and can be itchy. It can occur on various parts of the body, including the scalp, feet (often referred to as athlete's foot), and groin (known as jock itch). Ringworm is contagious and can spread through direct skin-to-skin contact or by sharing personal items like towels and combs. Treatment typically involves antifungal creams or oral medications, which help eliminate the infection. Maintaining good hygiene and keeping the skin dry can help prevent its spread.
