HPV51 positive is an infection of human papillomavirus subtype 51, which is a high-risk infection that can cause cervical precancerous lesions and even cervical cancer if the infection persists, so if the test is positive for HPV51, TCT should also be performed. If there is no abnormality in the TCT test, treatment to clear HPV infection should be actively carried out, such as vaginal application of anti-HPV bioprotein dressing, or vaginal application of Rebieson, as well as anti-HPV infection drugs such as interferon for effective treatment. You should also pay attention to keep your vulva clean and hygienic, and forbid eating cold, spicy and stimulating food during the treatment period, and try not to have sexual intercourse.
