Here is a very useful resource on Health Issues by Anup Shah. The resource/article was updated in 2014.
“This article looks at some global aspects of health issues, such as the impact of poverty and inequality, the nature of patent rules at the WTO, pharmaceutical company interests, as well as some global health initiatives and the changing nature of the global health problems being faced.”
