Guatemala has peak mosquito activity during the rainy season from May through October. The Pacific and Atlantic coastal lowlands, the Peten region, and areas below 1,500 meters carry the highest risk. Guatemala City and highland areas have lower but not negligible exposure.
Dengue fever is the primary concern, with significant outbreaks during the wet season. Malaria (P. falciparum and P. vivax) persists in lowland rural areas, particularly in the Peten and northern departments. Chikungunya and Zika have also caused outbreaks.
Aedes aegypti and Aedes albopictus transmit dengue, chikungunya, and Zika in urban and suburban areas during daylight hours. Anopheles species carry malaria in rural lowlands, biting at night.
