Africa is undergoing a major health transition marked by rising non-communicable diseases, climate-related health challenges, rapid urbanization, and changing population dynamics. Yet across many countries, health systems continue to rely heavily on fragmented and incomplete data, limiting their ability to respond effectively to emerging public health needs. Strong surveillance systems are essential for building resilient health systems because they provide continuous, reliable, and community-level data on disease patterns, mortality, migration, and healthcare access. Unlike routine facility-based reporting, surveillance systems capture the realities of how communities seek care, including informal pathways such as pharmacies, self-medication, traditional healers, and private providers. This helps uncover health trends and service gaps that may otherwise remain invisible in national health records. Health and Demographic Surveillance Systems (HDSS) also support early detection of emerging risks, strengthen cause-of-death reporting, monitor the effectiveness of interventions, and generate evidence that can guide policy and resource allocation. As African countries work toward universal health coverage and stronger public health preparedness, sustained investment in surveillance infrastructure, data integration, digital innovation, and long-term research systems will be critical. Resilient health systems depend on resilient data systems. Without strong surveillance, countries risk making decisions based on incomplete information, weakening their ability to plan, respond, and protect population health.
