Sudan faces inter-sectional health risks posed by escalating violent conflict, natural hazards and epidemics. Epidemics are frequent and overlapping, particularly resurgent seasonal outbreaks of diseases such as malaria, cholera. To improve response, the Sudanese Ministry of Health manages multiple disease surveillance systems, however, these systems are fragmented, under resourced, and disconnected from epidemic response efforts. Inversely, civic and informal community-led systems have often organically led outbreak responses, despite having limited access to data and resources from formal outbreak detection and response systems. Leveraging a communal sense of moral obligation, such informal epidemic responses can play an important role in reaching affected populations. While effective, localised, and organised—they cannot currently access national surveillance data, or formal outbreak prevention and response technical and financial resources. This paper calls for urgent and coordinated recognition and support of community-led outbreak responses, to strengthen, diversify, and scale up epidemic surveillance for both national epidemic preparedness and regional health security.
