Burkina Faso has peak mosquito activity during the rainy season from June through October. The entire country is malaria-endemic, with the highest burden in the south and southwest. The dry Sahel zone in the north has more limited but still significant seasonal transmission.
Malaria (P. falciparum and P. vivax) is the primary concern and a leading cause of mortality. Yellow fever is endemic. Lymphatic filariasis is present in southern regions. The intense but seasonal rains create concentrated periods of very high risk.
Anopheles gambiae is the dominant malaria vector. Aedes aegypti transmits yellow fever. The Sahelian climate means the dry season (November through May) offers significantly reduced mosquito exposure.
