Useful travel health link
There's a very comprehensive set of pdf mini-handbooks about travel health and safety put out by IAMAT (International Association for Medical Assistance to Travelers) here. I have no special expertise in this area, but I know that IAMAT has been around for a long time as a nonprofit advising travelers on health. They take contributions, but I don't think you need to be a member to use the information. Their pamphlets are very detailed, and I think would make a good supplement to CDC and other sources.
