HPV Risk Persists Later
- New reporting indicates women continue to acquire new HPV infections into midlife and older age. - One study found more than one in ten unvaccinated women tested positive within five years. - The finding challenges age-based risk assumptions used in some screening conversations and patient counseling (cidrap.umn.edu).
Human papillomavirus is common after first sexual activity, but new U.S. data show women can still pick up infections in midlife and older age. (sciencedirect.com) A study published in April 2026 in the *International Journal of Infectious Diseases* followed 3,379 unvaccinated U.S. women age 27 and older who had at least two human papillomavirus tests. Within five years, 11.4% had a new anogenital human papillomavirus detection. (sciencedirect.com) The incidence was 24.1 cases per 1,000 person-years overall, and the paper reported a second peak at ages 55 to 59. CIDRAP said the findings point to continued risk beyond what many patients associate with their teens and 20s. (sciencedirect.com) (cidrap.umn.edu) Human papillomavirus is the virus that causes nearly all cervical cancers, according to the National Cancer Institute. The Centers for Disease Control and Prevention says the virus also causes other anogenital cancers and some throat cancers. (cancer.gov) (cdc.gov) The new paper lands inside an existing U.S. policy gap. The Centers for Disease Control and Prevention recommends routine vaccination at ages 11 or 12 and catch-up vaccination through age 26, but for adults 27 through 45 it uses shared clinical decision-making rather than a universal catch-up recommendation. (cdc.gov 1) (cdc.gov 2) That guidance says most adults in the 27-to-45 age group do not need a vaccine discussion, even though some may still benefit based on likely future exposure. The 2026 study directly examined unvaccinated women in that older age range. (cdc.gov) (sciencedirect.com) Researchers have also found that a newly detected human papillomavirus infection in middle age is not always brand-new exposure. A 2021 Baltimore cohort study of women ages 35 to 60 found new sex partners sharply raised detection rates, but most new detections appeared to reflect reappearance of earlier infections. (academic.oup.com) Screening rules add another layer. The American Cancer Society says average-risk people with a cervix should continue screening until at least age 65, and the U.S. Preventive Services Task Force still recommends stopping after 65 only for people with adequate prior screening and no high-risk history. (cancer.org) (uspreventiveservicestaskforce.org) The new results do not change those national recommendations on their own. They add a newer number to conversations about vaccination, screening history, and sexual health that do not end at age 26. (sciencedirect.com) (cdc.gov)
