Resumo: In January 2005, an epidemic of chikungunya fever broke out in the Comoro Isl-s - lasted until May 2005. In April, cases were also reported in Mayotte - Mauritius. On Réunion Isl-, 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 - retrospective case detection around the cases reported, then relied on a sentinel network when the incidence increased. Emerging - 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 - 41 of maternoneonatal transmission, with an overall attack rate of 35%. Chikungunya infection was mentioned on 203 death certificates - significant mortality was observed. This epidemic highlighted the need for a mutual strategy of providing information on arboviral diseases - their prevention - control between countries in the southwestern Indian Ocean.
