Key Point The worldwide burden of HPV-related cervical disease and genital warts is considerable. Background According to estimates from the World Health Organization (WHO), the worldwide annual incidence of HPV infection is 660 million, 1 with low- and high-grade dysplasia being 30 million and 10 million cases, respectively. 2 The WHO estimates that 30 million cases of genital warts occur every year. 3 The largest number of cases of cervical HPV infection have no detectable cytologic abnormalities, and many of these cases are self-limited. However, an important subset will subsequently become associated with disease. 2 Together, HPV 16 and 18 are responsible for at least 70% of cervical cancers and at least 50% of high-grade lesions. 4 Together, HPV types 6, 16, and 18 are responsible for approximately 30% of low-grade lesions of the cervix, 4 and HPV types 6 and 11 are strongly associated with anogenital warts. 5 In a study by Gissmann and colleagues (N=63), HPV 6 and 11 DNA was detected in >90% of anogenital warts. 5 1.

Oncogenic HPV DNA sequences are found in more than 99% of cervical cancers globally. HPV infection is associated with cancers other than cervix. Oncogenic HPV DNA sequences are found in a proportion of anal, vulval, vaginal, penile and head and neck cancers and the precursor intra epithelial lesions. HPV 16 is again the dominant oncogenic type and overall the malignant burden attributable to HPV infection is calculated to be 5% of all cancers
