HPV can generally be divided into more than 160 subtypes, and the subtypes are divided into two major types, which can be classified into low-risk and high-risk types. Low-risk and high-risk HPV viruses cause different diseases and have different pathogenicity. Low-risk HPV viruses often lead to the development of genital warts, commonly HPV6 and HPV11. Long-term persistence of infection with high-risk HPV viruses may lead to malignant cervical lesions. The pathogenicity of high-risk HPV viruses also varies, with HPV16 and HPV18 being the most pathogenic and may lead to the development of 70% of cervical cancers, while HPV infections of types HPV31, HPV33, HPV52, and HPV58 are also more common in Asian women.
