Estimating the Global Burden of High-Risk HPV Infection in Girls and Women Aged 9 to 50 Years Across South Asia and Sub-Saharan Africa

What this Trial Is About

Researchers are estimating the prevalence of high-risk human papillomavirus HR HPV infections among girls and women aged 9 to 50 years across eight countries in South Asia and sub-Saharan Africa. This study aims to understand HPV infection rates in low socio-economic populations and specific sub-groups, including sexually active young women, by conducting cross-sectional surveys and longitudinal studies. Additionally, qualitative sub-studies will explore how gender norms and stigma affect HPV burden and access to prevention and treatment services. The study uses a harmonized protocol across all participating countries with country-specific adaptations. Cross-sectional surveys will collect urine samples from girls and women in urban and rural areas to estimate HPV prevalence. Longitudinal studies will follow sexually active girls and women aged 15 to 35 years over 24 months, collecting vaginal swabs and urine samples to measure persistent HPV infection. Qualitative studies will include interviews and focus groups to understand social factors influencing HPV risks and healthcare access. Participants will provide samples and answer standardized questionnaires on demographics, sexual and reproductive history, HPV vaccination, cervical cancer screening, and related attitudes. Testing will occur at enrollment and every six months for two years in longitudinal studies. Researchers will monitor HPV infection rates, assess questionnaire responses, and analyze laboratory results. The study includes safety follow-up and detailed data collection to provide comprehensive insight into HPV prevalence, incidence, and social influences in these populations.
