Type-specific prevalence and persistence of human papillomavirus in women in the United States who are referred for typing as a component of cervical cancer screening

Approximately one-third of our sample had HPV; of those women who were retested within 8-16 months, more than one-third had persistent infection. Among women with high-risk HPV infections, the likelihood of persistence was highest with HPV genotypes that were phylogenetically similar to HPV-16.
