HPV is human papillomavirus, HPV infection mainly causes proliferative lesions of human epidermis and mucous membranes.HPV infection is contagious and mainly spreads through the following ways. 1. Sexual transmission: most infections originate from HPV-infected individuals, and genital HPV transmission usually occurs through genital contact during sexual intercourse or anal sex. 2. Indirect transmission: HPV is transmitted indirectly through contact with objects contaminated with the virus, which is only a minority of cases because the isolated virus is difficult to survive for long periods of time.
