To the Editor: In their study on the prevalence of human papillomavirus (HPV) infection among American females, Dr Dunne and colleagues1 provided data that generate questions concerning how HPV is spread. Among the women in the study, 5.2% who reported that they never had sex tested positive for a presumably sexually transmitted disease. The authors' conclusion was that the women in the study were inaccurate in their answers. They also theorized that nonpenetrative contact could explain this finding.
