We previously proposed a compartmental model to explain the outbreak of Chikungunya disease in Reunion 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.
我们之前提出了一个隔室模型来解释 2005 年在印度洋法属留尼汪岛和其他国家爆发的基孔肯雅热疾病，以及与 2006 年爆发之间可能存在的联系。在本文中，我们想知道是否可以通过适当的蚊虫控制工具来控制或阻止 2006 年的疫情。基于基孔肯雅病毒的新结果、其对蚊子寿命的影响以及卫生当局进行的多项实验，我们研究了 2006 年用于控制疫情的几种控制工具。我们提出了模型的分析，并开发了一种新的非标准有限差分方案，以提供有和没有蚊虫控制的几种模拟。我们的初步研究表明，早期使用大规模喷洒和机械控制（如破坏滋生地）的组合可以是有效的，可以阻止或控制基孔肯雅感染的传播，对环境的影响很小。
