Prevalence by type varies somewhat by region, for reasons that are not yet known.

However, none are consistently associated with both except age: young women are less likely to show persistence and older women with persistence are more likely to be at risk of invasive cancer.

The importance of the transformation zone in cervical cancer has been extended to other HPV-induced cancers such as anal or tonsillar cancers.

Natural history studies show that HPV with normal cervical cytology and cervical intraepithelial neoplasia (CIN) grade 1 behave similarly, with the majority of both showing regression.

Epidemiological knowledge of HPV infection in the UK relies heavily on prevalence studies of HPV DNA in the cervical epithelium of women undergoing cervical sampling (Woodman et al, 2001; Kitchener et al, 2006) and usually relates to female subjects known to be sexually active.

These studies indicate the prevalence of current infection, as most HPV infections are transient and become DNA negative within 2 years (Moscicki et al, 2006).
