In January 2005, an epidemic of chikungunya fever broke out in the Comoro Islands and lasted until May 2005. In April, cases were also reported in Mayotte and Mauritius. On Réunion Island, the first cases were reported at the end of April. Surveillance of this epidemic required an adaptive system, which at first was based on active and retrospective case detection around the cases reported, then relied on a sentinel network when the incidence increased. Emerging and severe forms of infection were investigated. Death certificates were monitored. By April 2006, the surveillance estimate was 244,000 cases of chikungunya virus infection, including 123 severe cases and 41 of maternoneonatal transmission, with an overall attack rate of 35%. Chikungunya infection was mentioned on 203 death certificates and significant mortality was observed. This epidemic highlighted the need for a mutual strategy of providing information on arboviral diseases and their prevention and control between countries in the southwestern Indian Ocean.
2005年1月，科摩罗群岛爆发基孔肯雅热疫情，持续至2005年5月。4月，马约特岛和毛里求斯也报告了病例。留尼汪岛于4月底报告了首例病例。对此次疫情的监测需要一个适应性系统，该系统起初基于围绕报告病例进行的主动和回顾性病例检测，在发病率上升时则依靠哨点网络。对新出现的严重感染形式进行了调查。对死亡证明进行了监测。到2006年4月，监测估计基孔肯雅病毒感染病例达244,000例，其中包括123例重症病例和41例母婴传播病例，总体罹患率为35%。203份死亡证明提及了基孔肯雅感染情况，并观察到了显著的死亡率。此次疫情凸显了印度洋西南部各国之间就虫媒病毒疾病及其预防和控制提供信息的共同战略的必要性。
