We previously proposed a compartmental model to explain the outbreak of
Chikungunya disease in Réunion Island, a French territory in Indian Ocean,
and other countries in 2005 and 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, and 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, and we develop a new nonstandard finite difference
scheme to provide several simulations with and without mosquito control. Our
preliminary study shows that an early use of a combination of massive
spraying and 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.

Abstract
We previously proposed a compartmental model to explain the outbreak of
Chikungunya disease in Réunion Island, a French territory in Indian Ocean,
and other countries in 2005 and 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, and 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, and we develop a new nonstandard finite difference
scheme to provide several simulations with and without mosquito control. Our
preliminary study shows that an early use of a combination of massive
spraying and 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.
