Jamaica has year-round mosquito activity, with peak risk during the wetter months from May through November. The low-lying coastal areas, Kingston, and the southern plains carry the highest exposure. Mountainous interior areas like the Blue Mountains have reduced risk.
Dengue fever is the primary concern, with periodic outbreaks across the island. Chikungunya and Zika have also caused outbreaks. St. Louis encephalitis is present at low levels. Jamaica has no malaria transmission.
Aedes aegypti is the dominant vector, breeding extensively in urban water storage containers. Culex species are associated with St. Louis encephalitis. Resort areas typically have mosquito management programs, but risk remains during the wet season.
