HPV is the human papillomavirus, and its transmission routes mainly include direct contact transmission, indirect contact transmission, vertical transmission, and medical transmission. 1. Direct contact infection: most of the infections come from HPV infected people, and the transmission of genital HPV is usually spread through genital contact during sexual intercourse or anal intercourse. 2. Indirect contact transmission: HPV can be transmitted indirectly through contact with objects contaminated by the virus, which is less common because the virus can hardly survive for a long time after leaving the human body. 3. Vertical transmission: It is mainly transmitted from mother to child, and newborns can be infected through the birth canal of HPV-infected mothers in the process of delivery. 4. Medical transmission: in the process of diagnosis and treatment, if the health care personnel are not properly protected, it can lead to their own infections; secondly, improper operation of the medical personnel can also cause cross-infection between patients. It is recommended to go to the hospital for examination and treatment in time after being infected with human papillomavirus.
