The conversion of HPV is related to the degree of the disease and the immunity of the body, and cannot be generalized. HPV infection, also known as HPV infection, is mostly transmitted through sexual contact. Patients can bring the virus around the vaginal opening or from male genitalia into the cervix through sexual intercourse. Patients with HPV infection are checked for cervical TCT, and if the TCT is normal, no special treatment is usually needed. Patients with a strong immune system can gradually heal themselves in about 6-24 months, but they must have regular TCT. patients with persistent HPV infection can also be treated with recombinant human interferon, usually in a course of 3 months, and the patient will be re-checked 3 months after stopping the medication, and it will gradually turn negative in as early as 3 months, but most patients may take 1-2 years to turn negative. Therefore, if a patient is found to have the same high-risk type of infection for more than 1 year, a cervical TCT and, if necessary, colposcopy should be done at the same time to clarify the diagnosis and provide timely treatment.
