Dynamique de population et contrôle des vecteurs non domiciliés de la maladie de Chagas

Abstract : Chagas disease is a human and animal parasitic disease of Latin America. The parasite, Trypanosoma cruzi, is widespread in wild fauna populations and the disease is transmitted to man by insects of the Triatominae family, since men arrived in Latin America. Since the 1980‘s, large actions of prevention have been implemented to eliminate vectors inhabiting houses (domiciliated vectors). Although these initiatives have, overall, a resounding success, non-domiciliated vectors continue to spread the disease in several regions and generate significant prevalence in man. After assessing the presence and importance of different species of non-domiciliated vectors across the continent, a modeling approach was developed to refine our understanding of their populations and evaluate the potential of control methods. The confrontation between model and large data sets allowed the identification of key parameters of reproduction and migration of the vectors in the region of Yucatan, Mexico. These results were used to estimate several methods of control at the house level, the village level and then consider optimizing costs and benefits of vector control at a regional level in the Yucatan Peninsula. Although the proposed approach should be further strengthened, the results allow us to propose a general methodology for establishing priorities for research and treatment, relying heavily on the tools developed here: taxonomy mapping and optimization of vector control.
