Abstract
The last 30 years have seen a dramatic shift in global economies and a rise in the number and wealth of so-called “middle-income” countries. Notwithstanding the terrible toll of HIV-AIDS, survival rates have generally improved and with it an increase in the proportion of deaths due to chronic diseases as the infectious diseases decline (World Health Organization 2011). The World Health Organization (WHO) now has to face a rising epidemic of illnesses like diabetes as seriously as it has faced epidemics of infections like cholera or yellow fever (World Health Organization 2011).
