Given the severe neonatal diseases reported with other arbovirus infections, such as chikungunya [16] and dengue [10,12], we recommend close monitoring of per- inatal ZIKAV infections. Due to the high ZIKAV RNA load detected in breast milk, and even though no replicative ZIKAV particles were detected, ZIKAV transmission by breastfeeding must be considered.
Zika fever has been reported in tourists returning from French Polynesia to Japan in 2013–14 [21]. An outbreak of ZIKAV infection was also declared in February 2014 in New Caledonia, in the South Pacific [22]. Patients living in or returning from ZIKAV-endemic or epidemic areas presenting with a ‘dengue-like’ syndrome but testing negative for DENV should be tested for ZIKAV, with attention paid to infected pregnant women and their newborns, as data on the impact of the infection on them are limited
