Surveillance et évaluation du risque de transmission
des maladies vectorielles émergentes : apport de la capacité vectorielle
Exemple de la fièvre catarrhale du mouton

Abstract : Since 2000, vector-borne diseases have become a major threat in France and some European countries because of the emerging, the spreading and the persistence of pathogen virus coming from tropical and sub-tropical areas. Bluetongue is a good example of the progress of tropical arboviroses towards temperate zones under the effect of the expansion of its main vector in the European Mediterranean coastal (Corsica, Balearics Islands, Catalonia, Italy, Sardinia, Sicily, and Var)
The objective of this thesis is to both study methodological and diagnostic tools available for bluetongue risk evaluation and develop others in order to improve the surveillance of this disease in France.
Further the detection of C. imicola, the main vector involved in the viral circulation of bluetongue in Mediterranean basin, in the Argens Valley, the development of new tools for bluetongue surveillance and risk evaluation in areas where vectors have recently been established, has become absolutely necessary. An entomological study was carried out in the Argens Valley in order to i) confirm the establishment of C. imicola in this area, ii) monitor the dynamics of the vector population during the activity season, iii) collect entomological data to estimate the transmission potential of this established population. A stochastic model of vectorial capacity integrating field data about local C. imicola populations and data from literature is proposed. A study on the competence of C. imicola against the serotype 9 was also initiated.
The general discussion dwells on the points that seem to be essential to improve the surveillance system and progress towards the setting up of an early warning system. It also opens new perspectives to continue the integrative approach by including remote sensing results. Moreover, it poses the problem of the transition from a fine scale to a larger one. The research questions that raise the recent bluetongue epizootic in the northern Europe are, in the end, reviewed.
