Savoirs et pratiques autour de la tuberculose à Dakar, 1924-1969 : le destin d’une maladie sociale, du colonial au postcolonial

While strategies had been developed by the public authorities that had been operating in Dakar since the 1920s to contain the spread of tuberculosis, a social disease then identified as an obstacle to France's socio-political and economic projects in Dakar and West Africa, in 2019, some 40 years after Senegal's decolonization, the disease continued to be a concern for the city's health authorities. This raises several questions: Why, despite the manufacture of an anti-tuberculosis vaccine since the 1920s and the discovery of specific drugs in the 1940s and 1950s, tuberculosis continues to defy the plans implemented in Dakar to contain its spread? What has been done to halt its spread? Did the fight against tuberculosis in Dakar also involve action on the factors that contributed to the spread of the disease? Was it the implementation of TB control measures that was failing? The hypothesis underlying this thesis is that the fight against tuberculosis was not a priority for Dakar health authorities, but also that the inadequacy of the various preventive and curative measures against this disease explains the limits of the action taken so far and, consequently, the persistence of tuberculosis in this city. Through an evaluation of the organization and execution of the various measures taken since 1924, this thesis attempts to shed light on the factors explaining the persistence of tuberculosis in Dakar until 1969 and to identify continuities, and not only breaks, between the colonial and national periods in order to better understand the current place of the infectious disease in the country. It also envisages seeing with reference to what knowledge and practices were maked choices concerning measures to combat tuberculosis and seeks to study the modalities of implementation of the various measures adopted to halt the development of this disease in order to grasp distances between intentions and actions taken. In order to assess the impact of the various plans to combat tuberculosis in Dakar over the chosen period, attention is also paid to their reception and the attitudes that they have aroused among the population of Dakar.
