Human papillomavirus type-specific risk of cervical cancer in a population with high human immunodeficiency virus prevalence: case-control study.

There are limited data on human papillomavirus (HPV) type-specific cervical cancer risk among human immunodeficiency virus (HIV)-positive women. Previous studies have suggested that HPV 16 would be relatively less important as a causative agent among HIV-positive compared with HIV-negative women. This study investigates HPV type-specific cervical cancer risk in a population in which HIV is endemic.
