As international travel has burgeoned over the past 2 decades, investigators are looking at the illnesses travelers bring home as indicators of global disease trends and practical information that can help clinicians advise patients before and after traveling.
A recent study in Emerging Infectious Diseases reported trends from an 11-year analysis of about 42 000 travelers who visited 18 travel health clinics worldwide. According to researchers in the GeoSentinel Surveillance Network, a global collaboration of specialized travel and tropical medicine professionals, the destinations where travelers most often became sick were sub-Saharan Africa (26%), southeast Asia (17%), south-central Asia (15%), and South America (10%).
