Africa faces a disproportionate burden of infectious diseases, non-communicable diseases, and maternal-child health challenges, exacerbated by resource constraints, genetic diversity, and fragmented healthcare systems. Integrating preventive, predictive, and personalized medicine (PPPM; 3PM; 3P medicine) offers transformative potential to address these disparities through context-specific innovations, defined as solutions tailored to Africa's unique genetic architecture, disease epidemiology, healthcare infrastructure, socio-cultural environment, and economic constraints. This review examines the current progress, challenges, and future priorities for advancing 3P medicine in Africa, leveraging its unique genetic and phenotype diversities to achieve health equity. Key innovations include: Predictive tools : African-centric polygenic risk scores, machine learning models, and biomarkers. Prevention strategies : Tobacco control, metabolic syndrome screening, and hygiene education to reduce disease burden. Personalization : Pharmacogenomics for optimizing TB/HIV therapy, radiogenomics for cancer, and hypertension phenotyping. Critical barriers include infrastructural gaps, genomic data scarcity, workforce shortages, ethical concerns, political diversity and instability, fragile collaboration agreements, and lack of decision-maker advocacy. Priorities involve expanding biobanks, validating frugal diagnostics, and implementing AI-driven solutions. 3PM is imperative for sustainable African health equity. Success requires context-specific innovations, ethical governance, multi-ancestry research, and robust infrastructure.
