Among women, significant differences were seen based on all demographic characteristics, including income, race/ethnicity, and age. Among MSW, seroprevalence also differed by race/ethnicity. This was the only significant difference by demographic characteristic of MSM. Among all groups, there were significant differences in prevalence of HPV based on lifetime number of partners, with those people reporting one to four partners having lower rates than those reporting more than 10. In contrast, MSW had a seroprevalence rate of just 13.2%. Overall, the analysis found that HPV seroprevalence was similar in MSM (42.6%) and women (37.1%). The results are, therefore, based on 169 MSM, 6,074 women, and 5,325 MSW.
This analysis included only sexually experienced, unvaccinated individuals who completed a full sexual history and had been tested for HPV types 6, 11, 16, and 18. This study used data collected between 20. Participants complete a survey that includes questions about sexual behavior and visit a mobile exam center where they are tested for HPV among other things. The newest version of the HPV vaccine, called Gardasil 9, protects against these four types as well as five other high-risk types (31, 33, 45, 52, and 58).įor this prevalence study, researchers used data from the National Health and Nutrition Examination Survey (NHANES), which collects information from a nationally representative pool of noninstitutionalized adults. Specifically, types 6 and 11 cause most cases of genital warts, and types 16 and 18 cause 70% of cervical cancer.
Though most people won't suffer long-term health consequences and may never know they have the virus, others may develop cervical cancer or cancers of the head, neck, throat, penis, or anus.Ĭertain types of the virus are known to cause health issues.
The Centers for Disease Control and Prevention (CDC) estimates that 79 million people in the United States are infected with sexually transmitted HPV and 14 million new infections occur annually. There are 40 strains of the virus that are known to be spread through sexual activity. HPV is actually a group of more than 200 related viruses that can infect various parts of the body.
