CDC notes dramatic drops in HPV in females since vaccine introduced
Since the introduction of the human papillomavirus (HPV) vaccine in 2006, rates of HPV infections among females fell 88% in teens 14 to 19 years and by 81% in those aged 20 to 24 by 2018, according to a study today in Morbidity and Mortality Weekly Report (MMWR).
Vaccination against HPV, which is transmitted through sex, has been recommended for girls at age 11 or 12 years since 2006 and for boys since 2011 to prevent cervical, anogenital, and oropharyngeal cancers and anogenital warts. Catch-up vaccination is recommended for men and women through age 26.
The study, led by researchers from the Centers for Disease Control and Prevention (CDC), involved data from the National Health and Nutrition Examination Survey (NHANES) from 2003 to 2006 (pre-vaccine), 2007 to 2010, and 2017 to 2018.
Among sexually experienced females, HPV prevalence fell in those who reported receiving at least one dose of vaccine (-97% among 14- to 19-year-olds, -86% among those 20 to 24), as well as in those who remained unvaccinated (-87% among those aged 14 to 19, -65% among those 20 to 24).
The authors said that the substantial decreases among unvaccinated females suggest herd effects and may be related to a decrease in reported sexual behaviors among those aged 14 to 19. "These find?ings suggest strong herd effects, or indirect protection of unvac?cinated females, as reported in previous NHANES analyses and in data from other countries," they wrote. "The herd effects are likely attributable to less circulation of vaccine-type HPV because of both female and male vaccination in the United States."
The decline in HPV infections was first noted in the 4 years after vaccine introduction in the 14- to 19-year age-group and within 6 years in the 20- to 24-year age-group. While vaccine uptake has increased, it remains lower than that of other vaccines recommended for adolescents, the researchers said.
A drop in HPV vaccination during the COVID-19 pandemic threatens to reverse gains made thus far in HPV vaccination coverage, the researchers added, and efforts must be made to increase vaccination and to continue monitoring of infection data.

Report calls for broader approach to STI prevention and control
Despite a sharp rise in US sexually transmitted infection (STI) rates the over the past 20 years, STI prevention and control efforts remain underfunded, stigmatized, and detached from efforts to promote overall health and well-being, according to a new report from the National Academies of Sciences, Engineering, and Medicine (NASEM).
The report, which was commissioned by the CDC, argues that the nation's response to STIs has mostly focused on individual risk factors and individual behavior change, an approach that has tended to fuel blame and stigma. On top of that, the CDC's STI funding has remained flat over the past two decades, with a 40% reduction in inflation-adjusted dollars.
To address the growing epidemics of chlamydia, gonorrhea, and syphilis and strengthen the response to all STIs, the report recommends that public health agencies adopt a holistic approach that focuses on sexual health in the context of broader health and well-being. It calls for the Department of Health and Human Services (HHS) and state governments to broaden access to STI treatment and prevention by making it available through multiple venues, including comprehensive sexual health clinics, pharmacies, and urgent care settings, and to provide no-cost care options for patients to close coverage gaps.
The report also recommends that the National Institutes of Health prioritize development of rapid diagnostics, new antimicrobials, and vaccines for STIs, calls for support and expansion of the STI workforce, urges the CDC to partner with parents, parent-teacher associations, and school boards to establish guidelines for school-based sexual health education, and recommends that the CDC leverage social media for STI prevention efforts.
"With the release of this report and the creation of the first-ever HHS STI National Strategic Plan in December 2020, we have many opportunities to address structural barriers to STI prevention and care, minimize exposure to STIs, and ensure that services are easily available in welcoming, stigma-free environments," Sten Vermund, MD, PhD, dean of the Yale School of Public Health and chair of the committee that wrote the report, said in a NASEM press release.

Countdown starts for Guinea's Ebola outbreak
Guinea's last Ebola patient was discharged 2 days ago from a treatment center in N'Zerekore, which started the 42-day count down until the end of the country's latest Ebola outbreak, the World Health Organization (WHO) African regional office said today on Twitter.
The WHO added that the countdown started just 38 days after Guinea's outbreak began. The event marks Guinea's first since West Africa's massive outbreak between 2014 to 2016, and early genetic analysis suggests that the new flare-up was linked to that earlier outbreak, hinting at the possibility that the virus can persist in protected body sites such as the eyes or testes much longer than previously thought.
So far, Guinea has reported 18 cases, 9 of them fatal in the current outbreak. And nearly 4,000 people in the outbreak area have been vaccinated.
The latest announcement about Guinea's outbreak comes 2 days after the WHO announced that the last Ebola patient in the Democratic Republic of the Congo (DRC) left treatment, which began that country's countdown to the event being declared over.
