In many parts of the world, diseases that do not occur in the U.S. or rarely do can be quite common. Diseases such as yellow fever, typhoid, dengue fever, hepatitis A and B, meningitis, Japanese encephalitis, diphtheria, cholera and others can not only ruin a foreign trip but also place travelers at risk. Many people continue to travel abroad for business or pleasure, yet only a small percentage of these travelers protect themselves by getting immunized against travel-related diseases. There is no shortage of immunizations to help safeguard against travel-related diseases. Plan ahead and protect your health while traveling outside the U.S.
