Top 10 Causes of Death

The World Health Organization (WHO) regularly gathers information on disease, disability and mortality in order to provide a comprehensive assessment of the health of the world's population.

What is striking about their findings from a US perspective is the difference in diseases and causes of death between low and high income nations.

In a recent study, for example, the leading causes of death in low income nations are listed as lower respiratory infections, diarrheal diseases, HIV/AIDS and heart disease.

By comparison, in high-income nations, the four top categories for causes of death are: heart disease, stroke, lung cancer and Alzheimer (and other dementias).

According to the World Health Organization (WHO), the leading global causes of disease burden -- not necessarily the same as cause of death -- are infectious disease, particularly lower respiratory infections and diarrheal diseases.
