When I was preparing my trip to Asia and I was getting all the vaccinations required I stumbled upon a very interesting website developed by a team at Boston Children's Hospital called HealthMap. This site created by a team of researchers, epidemiologists and software developers provide realtime information about disease outbreaks from a broad array of infectious diseases.
The map is quite interactive allowing you to move around and zoom in / zoom out to get additional information about specific cities and regions. I was checking this site recently because of all the Ebola craziness in the media and I realized they offer now a section dedicated to this disease: http://healthmap.org/ebola/#timeline. If you are traveling I think this is a great site to have in your bookmarks.
