The retrospective mortality study was carried out in August and September by MSF Epicentre teams in the Toumtouma, Arkoum and Ourang camps, which were home to 6,000, 44,000 and 25,000 people respectively at the time. A representative sample of 3 093 people (heads of households) was asked about the number and cause of deaths in their household in 2023, before and after the start of the conflict.
This makes it possible to determine a crude mortality rate and compare it over the two periods. This is one of the most widely used indicators for assessing the severity of a crisis among a given population, given that a rate equal to or greater than one death per ten thousand people per day characterises an emergency requiring an immediate response.
The conflict in Sudan has led to a major humanitarian crisis in eastern Chad, where almost half a million people have found refuge, alongside already vulnerable local communities and thousands of other Sudanese refugees who have been in the country for two decades. Significant financial, logistical and human resources are still needed to step up the humanitarian response, particularly emergency food aid, in Adré and the surrounding camps.
MSF teams continue to provide a wide range of medical care in Adré hospital and in various clinics and health centres (paediatrics, maternal health, nutrition, trauma surgery, vaccinations, mental health, etc.) and to work to improve access to water, hygiene and sanitation services.
Epicentre is a Médecins Sans Frontières (MSF) satellite dedicated to epidemiology, medical research, innovation and training. Its experience and presence within MSF enable it to design and carry out projects in complex and often unstable situations, specific to humanitarian aid, to meet the health needs of populations and support MSF’s action.
