It is possible to have intercourse with a condom after HPV infection. The condom is an effective form of birth control and can also prevent cross-infection with many pathogens, such as vaginal inflammation, HPV infection and HIV infection. However, most of them are transient and can be cleared quickly by their own immunity within six months or a year. Only women with poorer body resistance have a combination of persistent HPV infections. In particular, persistent infection with high-risk HPV can lead to high-grade intraepithelial lesions of the cervix and can even lead to malignant tumors of the cervix.
