Chad — humanitarian situation

Chad continues to host the largest regional refugee influx from Sudan's civil war, which began in April 2023. As of 21 June 2026, 932,771 Sudanese refugees fleeing conflict between government forces and the Rapid Support Forces have crossed into Chad, with 918,249 registered or pre-registered (UNHCR). The majority have settled in eastern provinces: Ouaddaï hosts 55 percent, Wadi Fira 25 percent, Sila 11 percent, and Ennedi Est 9 percent. Relocation efforts have transferred 68.15 percent of refugees from spontaneous border sites to organized camps, though significant numbers remain in ad hoc settlements including at Adré and the established site at Dougui in Ouaddaï Province (UNHCR, ACTED). Health sector partners are responding to multiple disease threats across affected areas. Health Cluster members have conducted community-based mortality surveillance training in Bagasola and Liwa districts, while investigating and monitoring meningitis cases at Camp Aboutengué and Dodorok, including collection of eleven suspect case samples (WHO, Health Cluster). In May 2026, WHO and the Ministry of Public Health trained 77 health providers and community actors on surveillance, early detection, and case management of neglected tropical diseases in refugee-hosting areas, with 39 trained in Adré district and 38 in Goz-Beida (WHO, Health Cluster). Mental health services are also being strengthened, including training of 24 providers—18 men and 6 women—on psychological interventions (WHO, Health Cluster). The operational context is further complicated by anticipated El Niño conditions expected from mid-2026, which forecasting models suggest will be at least moderate strength with possibility of a strong event affecting the Sahel region (IASC, IFRC, OCHA). ACTED is conducting quarterly site profiling in Ouaddaï Province to assess vulnerabilities, specific needs, and service availability in order to improve humanitarian response planning and coverage. Regional funding data indicates ongoing resource constraints affecting response capacity across West and Central Africa (OCHA).
