Since HPV is contagious, its infection is mostly caused by direct or indirect contact. 1. Direct contact: For people with vulvar or cervical HPV infection, it is mostly spread through direct genital contact during sexual intercourse or anal sex. 2. Indirect contact: Infection occurs through indirect contact with items contaminated with HPV, such as toilet bowls in public areas, but because it is difficult for the HPV to survive for long periods of time after it has left the body, infection with the HPV through this route is only a minority. For patients infected with HPV, it is recommended that they go to the gynecology and dermatology departments of regular hospitals for consultation and active treatment under the guidance of doctors, so as not to cause cervical cancer, warts and other diseases.
