There is a high burden of genital wart (GW) recurrence among unvaccinated men across the lifespan and a need for vaccination to prevent multiple GW episodes, a new study found. The study was nested within a multinational prospective human papillomavirus (HPV) natural history study of men aged 18‒70 years in the US, Mexico, and Brazil, examined every 6 months for a median follow-up of 50.4 months. Subsequent GW events were defined as GWs detected after ≥16 weeks of the prior event. Among the findings:
- 44% of men experience ≥1 GW following the initial episode.
- Those with ≥2 subsequent events were at highest risk of continued GW experiences, with as high as 10 postinitial GW events.
- The incidence rate of each subsequent GW increased with increasing events.
- The proportion of GWs among HPV-6 and/or HPV-11-positive patients remained constant across events.
- ~63‒69% were positive for ≥1 of the 9-valent HPV vaccine types.
