French Polynesia (FP) is a French overseas territory of about 270,000 inhabitants in the Southeast Pacific, and one of the 22 Pacific Islands Countries and Territories (PICTs). Arthropod-borne virus (arbovirus) infections are major public health concern in the PICTs, with dengue virus (DENV), a Flavivirus of the Flaviviridae family, as the most common circulating and widespread arbovirus.1 In FP, DENV outbreaks have been recorded since the 40s.1–4 DENV used to be the only arbovirus isolated until October 2013 when FP experienced the largest outbreak of Zika virus (ZIKV) ever reported,5,6 followed by an outbreak of chikungunya virus (CHIKV) that started in October 2014.
