Resumo: Using geo-referenced case data, we present spatial - spatio-temporal cluster analyses of the early spread of the 2013-2015 chikungunya virus (CHIKV) in Dominica, an isl- in the Caribbean. Spatial coordinates of the locations of the first 417 reported cases observed between December 15th, 2013 - March 11th, 2014, were captured using the Global Positioning System (GPS). We observed a preponderance of female cases, which has been reported for CHIKV outbreaks in other regions. We also noted statistically significant spatial - spatio-temporal clusters in highly populated areas - observed major clusters prior to implementation of intensive vector control programs suggesting early vector control measures, - education had an impact on the spread of the CHIKV epidemic in Dominica. A dynamical identification of clusters can lead to local assessment of risk - provide opportunities for targeted control efforts for nations experiencing CHIKV outbreaks.
