Resumo: The re-emergence of local transmission of chikungunya virus caused by Aedes albopictus since March 2010 in the Réunion Isl-, French territory in the southwest Indian Ocean, calls for better epidemiological surveys, vector control, - community-based chikungunya control. This paper describes the strategy - the new ways of vector control applied since the last major chikungunya virus outbreak in 2005-2007, - the high levels of collaboration with mayors - local associations for community involvement. Between March 17, 2010 (first chikungunya case) - July 1, 2010, 313 cases were investigated, 13,036 premises inspected, - 34,393 premises concerned by spatial treatment. The traditional entomologic indices don't explain the distribution map of chikungunya cases, - many other factors have to be measured for evaluating the risk of transmission, such as lifestyle, habitat, - the kind of environment the people live in. A big information campaign was conducted beside the implementation of traditional mosquito control techniques. The two themes of this campaign are environmental management - individual protection, considered as important components of chikungunya prevention. The outcome of the mosquito control strategy demonstrates that community participation is not enough, - more studies are required to define new ways of communication for promoting community-oriented activities to prevent chikungunya epidemics.
