WHO Unveils Maiden Global Database for STI Prevalence Data

The World Health Organisation (WHO) has rolled out the world's inaugural global database designed to monitor the prevalence of sexually transmitted infections (STIs). This new initiative offers countries a centralized hub to access standardized and quality-assured data, thereby bolstering disease surveillance efforts and enhancing public health responses.

Announcing this groundbreaking development on Friday, the WHO stated that the open-access database marks the first global platform to bring together STI prevalence data specifically from low- and middle-income nations, covering information collected from 2010 onwards. The health body highlighted that this new resource effectively tackles long-standing difficulties in obtaining reliable country- and population-specific data by integrating both published and unpublished evidence from diverse sources into a single, accessible platform.

Dr. Tereza Kasaeva, who serves as the Director of WHO's Department for HIV, Tuberculosis, Hepatitis, and Sexually Transmitted Infections, lauded the database as a significant achievement in the worldwide campaign against STIs. She remarked, "This database represents a first major step forward in our ability to understand the burden of sexually transmitted infections across diverse populations and settings. By making these data openly accessible, we are equipping countries and partners with the evidence needed to design targeted interventions, strengthen surveillance systems, and accelerate progress towards reducing the global impact of STIs."

The WHO confirmed that the database currently encompasses five specific STIs: chlamydia, gonorrhoea, herpes simplex virus type 2, syphilis, and trichomoniasis. It added that the platform is structured to allow for expansion as more evidence becomes available. As of June 2026, the system hosts data from 766 studies, translating to 2,453 prevalence data points gathered from a broad spectrum of populations and environments.

These diverse sources include household surveys, studies involving pregnant women and adolescents, key populations, sex workers, and individuals attending STI clinics, alongside baseline data from intervention and case-control studies. The global health body emphasized that only studies adhering to stringent quality criteria were incorporated into the database. "These criteria include clearly defined population groups, adequate methodological information, sample collection conducted mostly from 2010 onwards, and study populations of at least 100 participants," the organization elaborated.

The agency further explained that the extensive body of evidence compiled within the database is expected to significantly improve the understanding of STI epidemiology, both within the general populace and among groups at a heightened risk of infection. The WHO also indicated that the platform will undergo regular updates as new studies are published and reviewed, with its scope set to broaden to include additional STIs as new public health priorities emerge.

Ultimately, the organisation's aim for this database is to assist policymakers, national disease control programmes, researchers, industry stakeholders, community organisations, and funding agencies by facilitating better access to STI-related data. It further noted that enhanced access to high-quality prevalence data will empower countries to formulate evidence-based interventions, reinforce surveillance systems, and refine regional and global estimates regarding the burden and evolving trends of STIs over time.
