What is the reason for the constant redness outside the vaginal opening of a 3.5-year-old girl?

Patient's question:

No

Doctor's answer:

This is a condition known as vulvitis in young girls, primarily due to the poor immune response of the vaginal skin and mucous membranes in children, making it prone to recurring episodes. It is important to maintain good hygiene of the external genitalia. The external genital area can be soaked in a 1:10,000 potassium permanganate solution. Subsequently, an antibiotic ointment should be applied to the area.
