The main aim of the study is to examine the relationship between climate variability and malaria transmission in Sub-Saharan Africa using Nigeria as a case study. For this study, climatic conditions considered suitable for its development and transmission through the mosquito stage of its life cycle are temperatures within the range 18°C to 32°C, but below 18°C parasite development decreases significantly. Above 32°C the survival of the mosquito is compromised. Relative humidity greater than 60% is also considered as a requirement for the mosquito to survive long enough for the parasite to develop sufficiently to be transmitted to its human host stage. The research findings show that seasonality of climate greatly influences the seasonality of malaria transmission.
