CBS in Chad
Community-Based Surveillance (CBS) was implemented in the district of Bongor (and partially in Goz Béida) as part of the Programmatic Partnership project funded by DG ECHO. This system aimed to strengthen early detection and rapid response to epidemics at the community level. The Chad Red Cross played a central role through the involvement of its 120 trained volunteers in the district of Bongor East and 80 in Goz Béida. These volunteers, in conjunction with community health workers, collected and transmitted health alerts, raised awareness among the population, and liaised with health facilities.
The French Red Cross provided technical support for CBS coordination, structures surveillance mechanisms, and assisted with monitoring activities. CBS was operational in eight health areas, including six in Bongor (Bongor Urbain 1 and 2, Bongor Sièké, Maguine, Biliam-Oursi, Djoumane) and two in Goz Béida (Doroti, Kerfi).
Diseases monitored varied by district: measles, yellow fever, COVID-19, poliomyelitis/PFA, Guinea worm, and mpox in Bongor; hepatitis E, tetanus, cholera, and others in Goz Béida.
The project set up a simple data collection system, adapted to local realities, with a strong awareness-raising component. Thanks to community mobilization and cross-support from the the Red Cross, CBS strengthened health resilience and limited the spread of epidemics in both districts.
