A new digital training model called Clinical Integrated Disease Surveillance and Response (cIDSR) is helping frontline workers respond faster and more effectively to disease outbreaks. This analysis from Resolve to Save Lives explains how the training overcomes the limitations of traditional training using a mobile-optimised, self-paced platform that guides health care workers through real patient scenarios covering disease detection, reporting and case management. More than 18,000 health care workers have enrolled and when cholera broke out in Nigeria in June 2024, a dedicated training module was live within 48 hours and completed by over 8,000 workers in five weeks. An Ebola module in Uganda followed similarly swift deployment in early 2025. Across both countries, the training produced statistically significant improvements in knowledge, pointing to its strong potential as a scalable, adaptable tool for building frontline epidemic preparedness.
