CENTRAL QUESTION: How does the spread of malaria in sub-Saharan Africa correlate with economic hardship?

Malaria is an infectious disease that affects millions of people each year. The economically debilitating effects of Malaria is a crucial topic of anthropological discussion.  Entire societies cannot function without fear of infection and amounting costs of disease prevention and treatment.  Even worse, most deaths are in children.  As a result of several factors discussed on the following pages, the parasite flourishes in sub-Saharan Africa.  The Anopheles mosquito, shown in the upper left-hand corner of this page, symbolizes the potential destruction of the illness as the mosquito vector for the parasite.  In accordance with economic distress caused by the disease, the same countries with high incidences of fatal malarial infections also have some of the lowest world Gross Domestic Product output levels.  This website provides possible reasons for this year after year correlation between the disease and poverty and looks into measures to end the cycle.
