Human papillomavirus type 16 (HPV16) is a common infection in the anogenital tract. HPV16 DNA detected in oral specimens has recently been identified as a risk factor for some oropharyngeal cancers. The reported prevalence of oral HPV infection from individual studies is highly variable. ⋯ HPV-16, a common anogenital infection, was rarely detected in oral specimens. However, a small but noteworthy proportion of healthy individuals have oral HPV infections with types known to cause cancer in the oral region.
