It is normal for an 8-year-old girl to have a small amount of vaginal discharge, which is milky white in color and without localized redness or swelling of the vulva. However, if the amount of leucorrhea is very high, and there is an odor or yellow color, and the girl complains of vulvar itching, this is an abnormal phenomenon, often caused by vaginal infection by pathogenic bacteria, it is advisable to go to the hospital for a routine laboratory examination of the leucorrhea, and use a cotton swab to take the discharge to the laboratory to understand the type of pathogenic bacteria infection, and then give treatment according to the specific situation. It is also advisable to take good care of this condition. It is best to do the necessary washing after each bowel movement, and girls are advised to change their underwear regularly and to expose the washed underwear to the sun for sterilization.
