Abstract
Traveler's medicine is becoming an increasingly important and widely applied subspecialty of infectious diseases, focusing mainly on prevention. With the rise in the standard of living, particularly in the Western world, there are more possibilities for travel, and thus exotic locations in developing countries have become more accessible. An unfortunate result is the importation of many infectious diseases, such as malaria, typhoid, yellow fever, and rabies, into Western countries. For example, since 1980, 9 of 24 cases of human rabies reported in the United States were acquired in Third World countries. Medical counseling of people interested in tourism to these areas must be precise and based on comprehensive and continuously updated information. Physicians must be aware of the smallest details (e.g., malaria prophylaxis is not needed in the touristic parts of Thailand but is a must in the northern forests of the country).
