Abstract

Universal access to HIV testing is fundamental to effective HIV prevention, timely treatment initiation, and epidemic control. Africa continues to shoulder the highest global burden of HIV, where delayed diagnosis remains a major driver of morbidity, mortality, and ongoing transmission. The World Health Organization (WHO) has provided sustained normative leadership through evidence-based frameworks, rights-centered policies, and programmatic innovations designed to expand HIV testing coverage and promote early diagnosis across diverse African settings. This narrative review synthesizes WHO guidance on provider-initiated and community-based testing, differentiated service delivery, and ethical standards, alongside key innovations such as HIV self-testing, integrated and dual rapid diagnostics, and mobile outreach models. Progress toward early diagnosis and the first UNAIDS targets is examined, highlighting gains in antenatal testing, male and adolescent engagement, and test-and-treat implementation. Persistent gaps—including late presentation, stigma, health system constraints, and sustainability challenges—are also discussed. The review concludes by outlining strategic priorities for strengthening equitable, data-driven, and resilient HIV testing services. Sustained implementation of WHO-led frameworks remains central to achieving universal access and ending AIDS as a public health threat in Africa.
