plague spread from Dakar to Yoff, Thiès, and even to Kaolack and Djourbel. The total loss of life can be estimated in the range of four to eight thousand. After 1919, the plague became endemic in Senegal. Although medical officials eventually came to appreciate that the rat flea was the principal vector of plague, public health measures remained focused on the control of Africans’ movements. The temporary disappearance of the plague by the 1930s seems to have been owing to natural causes, rather than French colonial interventions. In 1944, during the Second World War, another major outbreak of plague occurred. The Americans stationed in Senegal made decisive interventions, using DDT and sulfa drugs, after prevailing in a series of politico-medical conflicts with the French. After 1945, the plague disappeared from Senegal. Gracefully written and well-researched, Black Death, White Medicine makes an important contribution to the field of historical epidemiology and opens wide new windows on the history of colonial Senegal.
