The webpage “Health emergency readiness for response operations” on the OpenWHO platform presents an online learning course developed by the World Health Organization (WHO) to introduce the concept of operational readiness for health emergency response. The training explains how governments, health authorities and partners can prepare systems, procedures, resources and coordination mechanisms so they are able to respond quickly and effectively to outbreaks, disasters or other public-health emergencies. It covers key elements such as risk assessment, preparedness planning, coordination between organizations and the Minimum Operational Readiness Standards used to strengthen emergency response capacities. Overall, the webpage aims to help health professionals and emergency responders understand how to build and improve operational readiness so that health systems can react efficiently when emergencies occur.
