Fiji has year-round mosquito activity, with peak risk during the warm, wet season from November through April. The main islands of Viti Levu and Vanua Levu carry the highest risk, particularly in urban areas like Suva and Lautoka. Smaller outer islands may have lower exposure.
Dengue fever is the primary concern, with moderate activity and periodic outbreaks. Zika has caused outbreaks in recent years. Lymphatic filariasis is also present. Fiji has no malaria transmission.
Aedes aegypti and Aedes albopictus are the primary vectors. The tropical Pacific climate with heavy wet-season rainfall creates abundant breeding habitat. Tourism areas maintain better vector control but are not risk-free.
