Where Malaria Thrives: Climate, Mosquitoes, and Socioeconomic Factors

Malaria concentrates in tropical/subtropical regions: Sub-Saharan Africa, South/Southeast Asia, Middle East, Central/South America.

Environmental Drivers

• Temperature: Warmth accelerates Plasmodium development in Anopheles mosquitoes.
• Rainfall/humidity: Creates stagnant water (marshes, rice paddies, puddles) for mosquito breeding.

Socioeconomic Factors

Limited healthcare access, diagnostics, treatment, and prevention (e.g., insecticide resistance) increase transmission. Investments in vector control, education, and health systems reduce incidence.
