The Central African Republic has known long periods of instability. In 2014, following the fall of an interim government installed by the Séléka coalition, a series of violent reprisals occurred. These events were largely directed at the country's Muslim minority and led to a massive displacement of the population. In 2014, we sought to document the retrospective mortality among refugees arriving from the CAR into Chad by conducting a series of surveys. The Sido camp was surveyed exhaustively in March-April 2014 and a systematic sampling strategy was used in the Goré camp in October 2014. The survey recall period began November 1, 2013, just before the major anti-Balaka offensive. Heads of households were asked to describe their household composition at the beginning of and throughout the recall period. For household members reported as dying, further information about the date and circumstances of death was obtained. In Sido, 3449 households containing 25 353 individuals were interviewed. A total of 2599 deaths were reported, corresponding to a crude mortality rate of 6.0/10000 persons/day, and 8% of the population present at the beginning of the recall period died. Most (82.4%) deaths occurred among males, most deaths occurred in December 2013 and January 2014, and 92% were due to violence in the CAR. In Goré, 1383 households containing 8614 individuals were interviewed. A total of 1203 deaths were reported, corresponding to a crude mortality rate of 3.7/10000 persons/day [95%CI 3.5-3.9], and 12% of the population present at the beginning of the recall period died. Most (77.1%) deaths occurred among males. As in Sido, most deaths occurred in December 2013 and January 2014, and 86% of all deaths were due to violence in the CAR. The results of these two surveys describe a part of the toll of the violent events of December 2013 and January 2014 in the Central African Republic.
