ABSTRACT=ObjectivesTimely detection of infectious disease outbreaks is essential to limit health, social, and economic impacts, yet diagnostic and surveillance gaps persist across Africa. This review applies the 7-1-7 global target framework—detect within 7 days, notify within 1, and respond within 7—to assess strategies for strengthening early detection capacities across African countries.MethodsWe conducted a review of peer-reviewed literature, institutional reports, and field evidence published without time span limitations. Key themes were organized around five strategic pillars: diagnostic preparedness, surveillance, workforce development, community engagement, and governance.ResultsIdentified bottlenecks include limited diagnostic networks capacity, fragmented surveillance systems, workforce shortages, and underinvestment in digital infrastructure. Promising solutions include diagnostic network optimization, deployment of point-of-care molecular tools, integration of event- and indicator-based surveillance through interoperable platforms, and AI-enabled early warning systems. Field examples from Uganda, Senegal, and Nigeria demonstrate improved timeliness where coordinated investments and multisectoral collaboration have been implemented.ConclusionMeeting the 7-1-7 detection target requires integrated, country-owned strategies that align diagnostics, surveillance, workforce, and governance within resilient national health security frameworks, underpinned by sustained domestic investment.
