Ringworm is mainly caused by superficial fungal infections such as Trichophyton spp., Microsporum spp. and Tinea epidermidis. Clinically, ringworm is classified into ringworm of the head, ringworm of the body, and ringworm of the hands and feet depending on the location of the infection. Tinea capitis is subdivided into ringworm yellow caused by infection with Trichophyton rubrum, ringworm white caused by infection with Microsporum canis, Microsporum plasteri and Microsporum ferrugineum, and ringworm black spot caused by infection with Trichophyton purpureum and Trichophyton discontinua. Tinea corporis usually occurs on parts of the body other than the scalp, palms, plantars and nails, while ringworm is an infection that occurs in the groin area, perineum, perianal area and buttocks. The main causative fungi are Trichophyton rubrum, Trichophyton spp. and Trichophyton verrucosum. Ringworm is a fungal infection that occurs between the fingers and in the palms of the hands, while ringworm mainly involves the interdigital, plantar and lateral edges of the feet and is mainly caused by contact with Trichophyton rubrum, Trichophyton spp., Petromyces spp. and Flocculina epidermidis. Ringworm can be transmitted between patients and normal humans, as well as between animals and normal humans and between soil and normal humans. It can be caused by contact with, inhalation of, or ingestion of superficial fungi, so care needs to be taken in life to use separate everyday items from the patient and to boil and disinfect the patient’s clothing. At the same time, direct or indirect contact with diseased animals should be avoided, and good protection should be provided when going out in summer to cut off contact with disease-causing fungi in the soil from the source.
