Resumo: Réunion Isl- (Indian Ocean) has been suffering from its first known Chikungunya virus (CHIKV) epidemic since February 2005. To achieve a better underst-ing of the disease, a questionnaire was drawn up for hospital staff members - their household. CHIKV infected about one-third of the studied population, the proportion increasing with age - being higher in women. Presence of a garden was associated with CHIKV infection. The geographical distribution of cases was concordant with insect vector Aedes albopictus distribution. The main clinical signs were arthralgia - fever. The disease evolved towards full recovery in 34.4% of cases, a relapse in 55.6%, or a chronic form in 10%. Paracetamol was used as a painkiller in 95% of cases, sometimes associated with non-steroidal anti-inflammatory drugs, corticoids, or traditional herbal medicine. The survey provided valuable information on the factors that favour transmission, the clinical signs, the importance of relapses - the therapies used.
