Mozzwise Briefing

Benin has year-round mosquito activity in the humid south, with peak risk during the rainy seasons from March through July and September through November. The coastal lagoons around Cotonou, the Oueme River valley, and the northern regions all carry significant malaria burden.

Malaria (P. falciparum and P. vivax) is the primary concern and a major cause of morbidity. Yellow fever is endemic. The countrys varied climate zones mean transmission patterns differ between the humid south and the drier north.

Anopheles gambiae is the dominant malaria vector. Aedes aegypti transmits yellow fever. The southern lagoon environment and tropical humidity provide excellent mosquito breeding habitat year-round.
