French Polynesia has year-round mosquito activity, with peak risk during the warm, wet season from November through April. The Society Islands (including Tahiti and Moorea) carry the highest risk due to population density. The Tuamotu atolls have lower but present exposure.
Dengue fever has been reported at low levels, with periodic outbreaks. French Polynesia was notably the site of a major Zika outbreak in 2013-2014 that helped characterize the diseases association with Guillain-Barre syndrome. Lymphatic filariasis has historically been present.
Aedes aegypti and Aedes polynesiensis are the primary vectors. The French territorial health system provides surveillance, but the scattered island geography complicates control efforts.
