We have posted about Healthmap before, however, the current swine flu outbreak is exactly the reason why this site is awesome. It's extremely cool to check out the spread of an epidemic on a map. You can also view the data on google earth. The picture here was the healthmap of the swine flu at the time of posting.
Check Healthmap out. HINT: You can deselect all infections/diseases first and then just select the swine flu to get rid of all that background.
