Cameroon has year-round mosquito activity in the south and seasonal activity in the drier north, peaking during the rainy seasons from March through November in the south and June through October in the north. The entire country is malaria-endemic, with the forested south carrying the heaviest burden. Douala, Yaounde, and urban centers all have significant risk.
Malaria (P. falciparum and P. vivax) is the primary concern. Yellow fever is endemic. Chikungunya, Zika, and lymphatic filariasis are also present. The countrys diverse climate zones from coastal to Sahel mean transmission patterns vary significantly.
Anopheles gambiae and Anopheles funestus are the dominant malaria vectors. Aedes aegypti transmits dengue, yellow fever, and Zika. The tropical south has the most intense year-round transmission.
