Resumo: We previously proposed a compartmental model to explain the outbreak of Chikungunya disease in Reunion Isl-, a French territory in Indian Ocean, - other countries in 2005 - possible links with the explosive epidemic of 2006. In the present paper, we asked whether it would have been possible to contain or stop the epidemic of 2006 through appropriate mosquito control tools. Based on new results on the Chikungunya virus, its impact on mosquito life-span, - several experiments done by health authorities, we studied several types of control tools used in 2006 to contain the epidemic. We present an analysis of the model, - we develop a new nonst-ard finite difference scheme to provide several simulations with - without mosquito control. Our preliminary study shows that an early use of a combination of massive spraying - mechanical control (like the destruction of breeding sites) can be efficient, to stop or contain the propagation of Chikungunya infection, with a low impact on the environment.
