[Retrospective study of foot and mouth disease in West Africa from 1970 to 2003].
A retrospective study of foot and mouth disease in seven West African countries was conducted for the period 1970 to 2003. The study included three cattle-exporting Sahel countries (Burkina-Faso, Mali and Niger) and four cattle-importing coastal countries (Benin, Côte d'lvoire, Ghana and Togo). Foot and mouth disease has been enzootic in these countries since 1990/1991. Four of the seven serotypes are regularly notified (O, A, SAT 1 and SAT 2). In the seven countries as a whole, 198 biological samples from identified foot and mouth disease outbreaks confirmed the involvement of the following serotypes: O (62 outbreaks); A (32 outbreaks); SAT 1 (18 outbreaks); SAT 2 (86 outbreaks). This result, which is largely underestimated, clearly demonstrates the seriousness of foot and mouth disease in West Africa, whose livestock production system characterised by continual uncontrolled animal movements facilitates the spread of the disease. Unlike in Southern Africa, for foot and mouth disease to be controlled in West Africa it is necessary immediately to introduce a regional strategy involving all countries which takes into account the real situation in the field: transhumance, nomadism and live-animal imports by coastal countries.
