Which continent bears the highest burden of malaria?

Which continent bears the highest burden of malaria?

• A. Africa
• B. Asia
• C. South America
• D. Europe

Answer: (A)

Malaria burden is determined by how intensely and continuously transmission occurs in a region. In Africa, especially sub-Saharan Africa, transmission from Anopheles mosquitoes is perennial and intense, and Plasmodium falciparum—the parasite that causes the most severe disease—predominates. This combination leads to a very large number of infections and, unfortunately, many deaths, particularly among young children who have not yet built immunity. Socioeconomic factors, limited access to prevention (like bed nets and effective spraying) and treatment also contribute to making Africa bear the greatest share of malaria cases and fatalities. In Asia and South America, malaria exists but at lower and more variable transmission levels, and Europe has largely eliminated malaria through strong public health measures. Therefore, the continent with the highest burden is Africa.
