Travel Trends and Patterns of Travel-Associated Morbidity

Improved data collection methods have produced a clearer picture of travel-associated health risks and at-risk travelers. Examination of the causes of mortality and morbidity has led to a change in emphasis on ways of reducing morbidity. There are unanswered questions that relate to the contribution of medical comorbidities on travel-associated illness, how communication can enhance or influence behavior change, and the best strategies to influence the travelers at greatest risk. Enhanced data collection methods and better denominator data are necessary to provide more precise risk information and help inform policy and thereby reduce morbidity in tourists and travelers.
