HPV virus, also known as human papilloma virus, is mainly divided into high-risk HPV and low-risk HPV. Both high-risk HPV virus and low-risk HPV virus are contagious, and the main way of transmission is through sexual intercourse. Since men often have no obvious special symptoms when they have HPV virus infection, they are the easy source of infection and indirectly transmit it to women. When a woman has a high-risk HPV infection, it may stimulate cervical intraepithelial neoplasia or even cervical cancer, resulting in increased leukorrhea discharge and contact bleeding after intercourse. If a man is infected with low-risk HPV virus, but does not cause warts to appear, this will also be transmitted to women through sexual intercourse, and lead to women with low-risk HPV virus infection when they may also appear warts, that is why it is said that warts are a sexually transmitted disease. The HPV virus can also be transmitted through indirect contact, or mother-to-child transmission, but there is no research to confirm the diagnosis. If a woman is diagnosed with HPV infection, but there are no other abnormal problems and her resistance is low, she can be treated vaginally with Synflorin.
