Three Cases of Imported Dengue Virus Infection From Madeira to Belgium, 2012

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.
