Drawing on new and rather novel computer-aided mapping programs, scholars have been able to bring together a number of disparate data sources that deal with a diverse set of disciplines. One such project has recently appeared online, and it is called HEALTHmap. Created by a team of researchers based at the Harvard-MIT Division of Health Sciences & Technology, the project brings together aggregate data on diseases around the world, and in doing so, has created an important new way to visualize and think about various public health situations and potential epidemics. Specifically, the site draws on data from the World Health Organization, Google News, and the European Centre for Disease Prevention and Control. Using a series of boxes, visitors can toggle on and off various diseases on the world map, including dengue fever, meningitis, E.coli, and dozens more. Overall, it's a very good resource for anyone with an interest in public health or data visualization.
