Resumo: After an outbreak of Chikungunya infection in Emilia-Romagna Region (North-eastern Italy), a survey was performed to estimate the seroprevalence of antibody to Chikungunya virus - the proportion of asymptomatic infections, to identify factors associated with infection, - evaluate the performance of the surveillance system. The method used was a survey on a r-om sample of residents of the village with the largest number of reported cases. The prevalence was 10.2% (33 of 325), being higher in older people - males, - lower when window screens - insect repellents were used. Only 18% of infected persons were fully asymptomatic, 85% of the 27 symptomatic confirmed cases satisfied the surveillance case definition, - 63% of the persons meeting the criteria for suspect case were identified by the active surveillance system. This study provides basic parameters for modeling the transmission potential of outbreaks - planning control measures for Chikungunya infection in temperate settings.
