Ringworm results from fungi that grow on the skin, establish the infection and spread out in rings, according to WebMD. Ringworm is contagious and spreads through skin-to-skin contact with an infected person. An infected person can treat ringworm by taking oral antifungal medication or by applying antifungal creams, reports MedicineNet.
Ringworm results from an infection from skin fungi known as dermatophytes, explains MedicineNet. The fungi invade the outer layer of the skin and feed on the dead keratin layer, but they do not penetrate deeper layers of the skin. An individual can get ringworm by having skin-to-skin contact with an infected person or by sharing personal items such as towels, sports gear or clothing, reports WebMD.
Antifungal creams that treat ringworm contain clotrimazole, miconazole, ketoconazole and naftifine, notes MedicineNet. Some of these antifungal creams are available over the counter and can clear the infection within two weeks of application. Oral medication helps in the treatment of fungal infections that are unresponsive to the external application. Antifungal medication helps kill the fungi and prevent the recurrence of the condition, notes WebMD. Antifungal agents such as medicated shampoos, lotion, creams and powder can help treat ringworm by application on the whole body.
