Abstract

We report three laboratory-confirmed dengue virus (DENV) infections imported to Belgium by travelers returning from Madeira (Portugal). Despite the use of a mosquito-repellent spray as reported by two patients, the infection could not be prevented. Diagnosis was made by antigen detection and real-time reverse transcriptase polymerase chain reaction (RT-PCR) in two cases and by serology 1 month after onset of symptoms in a third one. The responsible virus was identified as DENV serotype 1, American/African genotype (genotype V). The close relationship to isolates from Colombia supports the previous findings that a South American strain originated the outbreak in Madeira in 2012.
