This is the tenth report summarizing the multi-country health situation and WHO’s response to the regional emergency caused by the conflict in Sudan. More than 14.5 million people are forcibly displaced due to the regional crisis-the largest number in the world-and nearly four million have fled to neighbouring countries, including Egypt, South Sudan, Chad, Ethiopia, Libya, Central African Republic and others. As the Health Cluster lead agency, WHO ensures the coordination across partners and the strategic approach of the humanitarian health response.
