Resumo: At the end of 2013, chikungunya virus (CHIKV) emerged in Saint Martin Isl-, Caribbean. The Asian lineage was identified. Seven months after this introduction, the seroprevalence was 16.9% in the population of Saint Martin - 39.0% of infections remained asymptomatic. This moderate attack rate - the apparent limited size of the outbreak in Saint Martin could be explained by control measures involved to lower the exposure of the inhabitants. Other drivers such as climatic factors - population genetic factors should be explored. The substantial rate of asymptomatic infections recorded points to a potential source of infection that can both spread in new geographic areas - maintain an inconspicuous endemic circulation in the Americas.
