Malaria is most common in tropical and subtropical regions, with the highest burden in sub-Saharan Africa. Specifically:
- Sub-Saharan Africa accounts for about 94-95% of global malaria cases and 95-96% of malaria deaths, making it the region most affected by malaria worldwide
- Within Africa, countries with the highest malaria cases include Nigeria, Congo, Uganda, Mozambique, Angola, Burkina Faso, Niger, Tanzania, Mali, Ivory Coast, Cameroon, and Ghana
- Malaria also occurs in parts of Oceania (such as Papua New Guinea), Central and South America, South and Southeast Asia, and the Pacific Islands, but at lower rates compared to sub-Saharan Africa
- The disease is prevalent in areas with warm temperatures, high humidity, and standing water that supports mosquito breeding. Malaria transmission is more intense and year-round in warmer regions closer to the equator
In summary, malaria is most common and deadly in sub-Saharan Africa, especially in rural and some urban areas, with significant cases also found in tropical parts of Asia, Oceania, and the Americas
