Cape Verde has limited mosquito activity compared to mainland West Africa, with peak risk during the brief rainy season from August through October. The islands of Santiago and Santo Antao have historically had the highest mosquito exposure. The dry, windy conditions on most islands limit breeding habitat.
Dengue fever has been reported at low levels, with periodic outbreaks. Cape Verde has achieved significant malaria reduction and is nearing elimination. The arid island climate naturally limits mosquito populations compared to the mainland.
Aedes aegypti is present on several islands and is the primary dengue vector. The volcanic island terrain and generally dry conditions mean risk is concentrated around areas with water storage and limited natural standing water.
