HPV is the general term for human papillomavirus, and there are more than 100 subtypes, divided into high-risk and low-risk types. Most HPV viruses are transient infections that cause no symptoms and can be cleared by autoimmune function. The symptoms of HPV infection vary depending on the type of HPV infection. Most HPV infections do not cause any symptoms, but continued infection with high-risk types of HPV can lead to cervical lesions and intraepithelial neoplasia of the cervix, which can lead to contact bleeding or abnormal leukorrhea. For women with low-risk HPV infection, the most common cause is the induction of condyloma acuminatum, which manifests itself as the appearance of cauliflower-like growths in the vulva or vaginal opening or vaginal wall, without obvious pain, and requires medication or laser treatment.
