If you like your data in map form then here are a couple of sites you might want to explore over the holiday weekend.
First up is the Global Atlas of Infectious Disease, I did get quite a few broken links there but there's still some nice maps in the infectious disease section.
The Worldmapper website takes an interesting approach to mapping geographic data. It uses an algorithm that distorts the size of the country to represent the value of interest. The example shown below is HIV prevalence (proportion of people 15-49 with HIV). They have a number of such maps for diseases (eg TB, Cholera, Rabies, Influenza etc) and a whole range of other categories.
