HPV is a virus, which is human papillomavirus in Chinese. There are many types of HPV virus, and the threat to people is divided into high-risk and low-risk types. High-risk HPV infection is the main cause of human cervical cancer, with high-risk HPV types 16 and 18 being the most important. In contrast, low-risk HPV viruses cause some skin diseases such as flat warts and condyloma acuminata, most of which have no obvious symptoms and rarely cause life-threatening diseases. The main way of HPV infection is sexual transmission, so the infection rate is higher in women who are sexually active, but not all people are infected by HPV virus is sexually transmitted, close contact, indirect contact, medical source of infection may lead to HPV virus infection. HPV infection is usually no obvious discomfort, some patients may have bleeding during intercourse, abnormal leucorrhea, etc. HPV infection is sometimes seen in men who have not yet had sex and it is normal to see people infected with HPV. In fact, 90% of women may have been infected with HPV during their lifetime, but under normal circumstances, the body’s immune system will eliminate it on its own. As with the common cold, some people have a viral infection, but the body’s immunity is strong and the immune system “eliminates” it before it can play its role, as is the case with the HPV virus. If you are already infected with HPV, there is no need to panic. It usually takes several years from precancerous to cervical cancer. If the lesion is mild, it needs active anti-HPV treatment and intravaginal administration of interferon, and regular review.
