Travel-related disease
A disease to which travelers are susceptible specifically because of their travel. Travel-related diseases are the purview of travel medicine. Travel medicine is not really new but it began to flourish in the 1980’s, due to the growing numbers of people traveling internationally, especially to less developed areas of the world. Destinations once visited only by soldiers, missionaries and explorers became destinations for ordinary travelers from western countries. Along with the increase in this type of travel comes exposure to health risks that, in large part, are new to the western world.
There are scores of travel-related diseases. They include, but are not by any means limited to the following entities listed as travel-related diseases by the National Center for Infectious Diseases of the CDC (Centers for Disease Control and Prevention).
