Ringworm is a common fungal infection that affects the skin, hair, or 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 spread through direct contact with an infected person, animal, or contaminated surfaces. Treatment for ringworm typically involves antifungal creams or medications prescribed by a doctor. Maintaining good hygiene, such as washing hands regularly and keeping skin dry, can help prevent the spread of the infection. If left untreated, ringworm can persist and spread to other areas of the body.
