In children, vulvar redness, itching, pain, and increased discharge are the main causes of vulvovaginitis and vaginitis, mostly bacterial infections, but also fungal infections, and related tests such as smear and culture of vulvar and vaginal secretions should be done to confirm the diagnosis of the infection. The disease is easily recurring, especially in patients with a long history of chronic disease. In addition to treatment, it is important to wash the vulva daily, wear clean and breathable cotton underwear, and avoid spicy and sweet diets during the illness. The disease is also prone to recurrence when the child has an infection (e.g., cold, throat inflammation), so attention should be paid to actively controlling the infection.
