Published data showed that dengue virus type 1 introduced from South America was the incriminated virus. We aim to determine the origin of the strain introduced to Madeira by travellers returning to Europe. Using phylogeographic analysis and complete envelope sequences we have demonstrated that the most probable origin of the strain is Venezuela.engVoRhttp://creativecommons.org/licenses/by-nc-nd/4.0/Dengue feverMadeiraSouth AmericaDengue virus 1Travel infectionDisease OutbreaksGenotypeCluster AnalysisDengueDengue VirusGene Products, envHumansMolecular EpidemiologyPhylogeographyPortugalSequence Analysis, DNAVenezuelaAttribution-NonCommercial-NoDerivatives 4.0 Internacional25843502217713.e5-810.1016/j.cmi.2015.03.0161469-0691Clinical Microbiology and Infection : the official publication of the European Society of Clinical Microbiology and Infectious Diseasesopen access
