Relative to other publicly available chikungunya sequences, the Bolivian samples represent a monophyletic group, suggesting that a single lineage was widely circulating in the country between February and May 2015.enChikungunyaBiologyOutbreakVirologyGenomeVirusLineage (genetic)AlphavirusMonophylyGeneticsarticle
