Ringworm is a fungal infection that can cause a circular rash on the skin, which is usually red, itchy, and scaly. It can appear anywhere on the skin and is often called tinea corporis. Ringworm is not caused by a worm, but by mold-like fungi that live on the dead tissues of the skin, hair, and nails. It is highly contagious and can be spread through direct skin-to-skin contact with an infected person, animal, or object. Ringworm can also be spread through contact with infected soil, although this is rare. The fungi that cause ringworm are everywhere, but it is more common in warm and humid weather.
Ringworm can be treated with antifungal medication, which is available over-the-counter or as a prescription. The treatment depends on the severity and location of the infection. Over-the-counter antifungal creams, lotions, or powders may work for mild cases of ringworm on the skin. Some of the most popular ones are clotrimazole and miconazole. If the infection is severe or on the scalp, prescription medication may be necessary. It is important to keep the skin clean and dry, wear flip-flops in locker rooms and public showers, and change socks and underwear at least once a day to prevent the spread of ringworm. If a rash does not begin to improve within two weeks of using an over-the-counter antifungal product, it is recommended to talk to a doctor as prescription medication may be needed.
