More of the Equation: need (n)

Here are some pictures that demonstrate the need for trained healthcare workers.

  This article was published in December 2011 in the New England Journal of Medicine highlighting the disparities in the distribution of healthcare workers worldwide.  These areas of purple shading are the places of the most critical shortages of healthcare workers, including Kenya.  

 In the figure, there is a graph plotting percentage of global health workforce, and disease burden.  The size of the dot represents the percentage of healthcare expenditures.  Sub-Saharan Africa bears 24% of the world’s disease burden but has only 3% of the global health workforce.
