Figure 1. Epidemiology of type 1 diabetes incidence and parasitic disease burden.

(A) Incidence of type 1 diabetes is increasing rapidly in the developed world. Nations with top quartile diabetes incidence among children age 0-14 are colored red, and nations with bottom 75% incidence are colored grey. Data are from the International Diabetes Federation [12]. (B) Global disease burden from parasitic diseases, including schistosomiasis, lymphatic filariasis, onchocerciasis, leishmaniasis, ascariasis, trichuriasis, and hookworm, is clustered in the developing world. Nations in the top quartile of disability adjusted life year (DALY) burden from parasitic diseases are shown in red and nations in the bottom 75% of DALY burden are shown in grey. Data are from the World Health Organization [13].
