Ringworm in women is caused by a fungal infection that is transmitted through direct or indirect contact, and can also be caused by the spread of infection through one’s own ringworm of the hands, feet, and nails. The common fungal pathogens of ringworm are mainly caused by Trichophyton rubrum, Trichophyton suis and Trichophyton floccosum. There is a risk of infection by sharing clothes, shoes and socks, bath tubs and towels with the patient. The skin around the perineum, groin and anus is thin and tender, warm and moist, and often rubs against underwear, so the fungus can easily attach and multiply. After the germs adhere and colonize, they will cause skin inflammation and illness. In addition, the spread of infection lesions in other parts of the body can also lead to ringworm. When ringworm occurs, it is recommended to consult a doctor in time for targeted treatment or therapy. Normally, the skin should be kept dry and clean, avoiding prolonged dampness. Pay attention to personal hygiene, and regularly wash and disinfect towels, clothes and bed sheets.
