Nicaragua has peak mosquito activity during the rainy season from May through November. The Caribbean lowlands, Managua, and the Pacific coast carry the highest risk. The Atlantic coast region (RAAN and RAAS) has additional malaria exposure in rural communities.
Dengue fever is the primary concern, with major outbreaks in urban areas during the wet season. Malaria (P. falciparum and P. vivax) persists in the Caribbean lowlands. Chikungunya and Zika have also caused significant outbreaks.
Aedes aegypti is the dominant dengue vector in cities and towns. Anopheles species transmit malaria in the Atlantic coast lowlands. The tropical climate and abundant rainfall support high mosquito density throughout the wet season.
