Leukocyte cleanliness level IV means severe vaginitis and treatment is recommended.
The common causes of severe vaginitis are: unclean sex or cross infection after sex; lack of good hygiene, such as infection caused by not washing underwear separately from socks, etc.; untreated vaginitis; and decreased resistance in the elderly.
It is recommended that you should not have intercourse the day before going to the hospital for a white belt test, and it is best not to give vaginal plugs for three days. It is a routine test to confirm whether the patient has vaginitis. Generally, cleanliness level IV means that no normal vaginal bacteria are seen under the microscope, and pus cells and miscellaneous bacteria are the main flora. In the case of mold, vaginal plugs and sodium bicarbonate baths should be given.
In short, leuko-cleanliness IV means severe vaginitis and must be treated gynecologically, usually with local medication for about 7 days and then stopping for 3 days for a review.
