Fig. 1 — Maps of Mali showing four study sites and four malaria epidemiological patterns [6, 24]. Annual isohyets (mm) separate each climatic zone. The climatic zones from north to south are as follows: Saharian zone (malaria transmission is sporadic to epidemic), Sahelian and Sudano-Sahelian zones (hyper-endemic for malaria, short transmission season of 3–4 months), Sudano-Guinean zone (hyper-endemic for malaria, long transmission season of 4–6 months). In the urban area of Bamako, conditions are not favourable for malaria transmission (hypo-endemic malaria)
