Roads and Malaria Transmission: Unveiling the Epidemiological Impacts of Transport Infrastructure on Anopheles Mosquito Ecology in Sub-Saharan Africa
Transport networks such as roads and highways are essential for economic growth and connectivity, yet their unintended ecological consequences can exacerbate malaria transmission dynamics. This review explores the multifaceted role of road construction and maintenance in shaping Anopheles mosquito habitats. Poorly planned roads often create stagnant water pools in borrow pits and ditches, providing breeding grounds for malaria vectors. Increased human mobility along transport corridors further enhances parasite circulation across regions. The review synthesizes evidence on road-induced ecological modifications, epidemiological implications, and potential mitigation strategies. Emphasis is placed on integrating vector ecology into road engineering, improving drainage design, and fostering collaboration between health and infrastructure sectors. By highlighting best practices and knowledge gaps, this review underscores the need for eco-sensitive infrastructure development to curb malaria risks while sustaining socioeconomic benefits.
