Immunizations for international travelers.

Immunizations for international travel are an important component of pretravel medical care. Travelers should receive protection against vaccine-preventable exotic diseases, and their immunity against common infectious diseases should be reviewed and updated. There are no immunizations for some important infectious hazards of travel. In the course of considering a traveler's risk for exposure to infectious disease on the basis of geographic destination, style of travel, and anticipated activities, the health care provider should discuss preventive measures and personal behavior with regard to food and water, avoidance of insect bites, personal safety, and sexual activity.
