Figure 1. The Burkitt lymphoma belt overlaps the regions of Africa in which malaria is holoendemic.

Figure 1

The grey belt shown on the map of Africa represents the areas in which Denis Burkitt's surveys found Burkitt lymphoma to be endemic. The black horizontal stripes represent regions of Africa in which the temperatures and rainfall support holoendemic malaria. Kampala is where Denis Burkitt treated his patients; the Gambia is one site where the role of malaria as a cofactor for causing Burkitt lymphoma was demonstrated.
