Cholera continues to pose a significant global health challenge, with over half a million cases and 7,000 deaths reported in 2025 across 32 countries. The World Health Organization (WHO) has classified the cholera emergency as a Protracted Grade 3, indicating persistent transmission and emergency conditions. Effective surveillance is crucial for outbreak detection and response, but many areas face underreporting and limited laboratory capacity, particularly in humanitarian contexts. Innovations in cholera surveillance, including global data workflows and serological approaches, are being explored to enhance early detection and risk assessment. Notable discussions during a recent WHO event included global surveillance efforts, regional risks in the Eastern Mediterranean, and case studies from Sudan.
