Tinea capitis is usually caused by fungal infections, and the causative organisms are Trichophyton spp., Microsporum spp. and Epidermophyton spp. Among them, Trichophyton rubrum is the most common, but also Trichophyton spp. and Trichophyton verrucosum. The common symptom of ringworm is a small papule that gradually expands outward, with a tendency for the center to heal on its own, in a circular or polycyclic shape, surrounded by a ring of papules, blisters, crusts or scales high above the skin surface, with clear boundaries. Ringworm can be spread by contact, and it is possible to contract the fungus and develop various skin symptoms when you come into contact with people or pets who have the fungus, or when you touch items such as clothing, bath towels, or washcloths that they have touched. The body is more susceptible to infection when the immune system is weakened and when it is in a humid and polluted environment. The treatment of ringworm is mainly antifungal, and can be treated with imidazole or acrylamide drugs used topically or orally. It is also important to pay attention to personal hygiene, not to share clothing, bath towels, and towels with others, and to wear clothes that are as loose and breathable as possible. Tinea capitis can be cured after active treatment, but some patients may have pigmentation on the lesions and may have recurrent attacks if the medication is not sufficient or is stopped prematurely.
