Case Studies of Malaria Surges after Extreme Climate Events in East and West Africa

Nagawa Jackline Irene

Malaria remains one of the most prevalent and deadly infectious diseases in sub-Saharan Africa, where it continues to burden public health systems despite global efforts to control and eliminate it. Climate change has exacerbated malaria transmission, with extreme climate events such as floods, droughts, and temperature fluctuations significantly influencing the spread of the disease. This review examines case studies from East and West Africa, regions where the impact of climate change on malaria transmission has been particularly pronounced. The study highlights the correlations between extreme climate events and surges in malaria incidence, focusing on the role of climate variables like temperature, rainfall, and humidity in facilitating mosquito breeding and parasite development. East Africa, with its varied topography, and West Africa, with its tropical climate, have both experienced notable malaria outbreaks linked to climate anomalies. These case studies underscore the complex relationship between climate variability and malaria transmission, revealing the need for localized, evidence-based strategies to address these challenges. The review emphasizes the importance of integrating climate-sensitive malaria control strategies into public health systems, which include improving weather forecasting, utilizing climate data for early warning systems, and enhancing surveillance efforts. Given the increasing frequency of extreme weather events due to climate change, this research advocates for adaptive public health responses that can mitigate the impact of malaria surges and safeguard vulnerable populations in Africa.
