Human papillomavirus, or human papillomavirus, is a DNA virus that can only infect human skin and mucous membranes, or HPV for short, and can cause warts, cervical cancer and other diseases. Immunologically, according to the heterogeneity of HPV genes, it is divided into two groups: skin HPV genotypes and mucosal HPV genotypes. The former mainly infects the hands and feet, causing common warts and plantar warts and other damages, such as HPV-1 type infection of the skin causing common warts; while the latter mainly infects the anogenital tract and oral mucosa, causing benign papillomas, warts or malignant diseases. Clinically, HPV is classified into low-risk and high-risk types according to its oncogenic properties, with low-risk types mainly causing benign tumors and proliferative lesions (e.g., HPV-6, HPV-11), while high-risk types mainly include HPV-16, 18, 31, 33, 35, 45, 52 and 58, which are associated with the development of cervical cancer. If HPV infection is detected, you should go to the hospital in time and take treatment with the help of your doctor to prevent further progression of the disease.
