HEALTHMap comes from the Children's Hospital Informatics Program, Boston, MA, and Harvard and MIT. It presents data on the incidence of several important infectious diseases, but in graphical form. Information is fed from a number of sources including Promed-Mail, and Euro Surveillance, and you can select the diseases you are interested in. You can also look at a particular country in detail.
