HPV is a general term for a group of viruses that form a family with similar viral morphology but different DNA restriction endonuclease profiles. About 35 types of HPV can infect women’s genital tract, and about 20 types are associated with tumors. According to the risk of tumor occurrence of different HPV types, there are low risk HPV types and high risk HPV types. Low risk HPV types include HPV 6, 11, 42, 43, 44 and other types, which often cause benign lesions such as external genital warts including cervical intraepithelial lesions (CIN I), high risk HPV types include HPV 16, 18, 31, 33, 35, 39 45, 51, 52, 56, 58, 59, 68 and other types are associated with the development of cervical cancer and cervical intraepithelial lesions of high grade (CIN II/III), especially HPV types 16 and 18. Human papillomavirus (HPV) is one of the smallest DNA (deoxyribonucleic acid) viruses. HPV is spherical in shape, approximately 45-55 nm in diameter, and infects mainly epithelial cells, with humans as the only host. To date, more than 70 subtypes of HPV have been identified, with information reported for more than 100 HPV subtypes. HPV is widespread in nature, and HPV infection in humans is very common and the infection rate is high. Almost half of the population has “dealt with” HPV during their lifetime.
