Venezuela has year-round mosquito activity in most of the country, with peak risk during the rainy season from May through November. The Caribbean coastal region, the Maracaibo basin, and the Orinoco Delta carry the highest risk. The healthcare infrastructure crisis has weakened vector control and disease surveillance in recent years.
Dengue fever is the primary concern, with high activity. Malaria (P. falciparum and P. vivax) has resurged dramatically, particularly in Bolivar state and mining areas. Chikungunya, Zika, yellow fever, and West Nile virus are also present. The deterioration of public health services has amplified all mosquito-borne disease risks.
Aedes aegypti drives dengue and Zika transmission in urban areas. Anopheles species transmit malaria in the south and mining regions. The collapse of vector control programs means mosquito populations are largely uncontrolled.
