This article presents a study on the types of travelers and the research conducted on them in the field of travel medicine. The study found that there were differences between the proportion of publications and the volume of travelers in certain groups. For example, while tourists made up the highest volume of travelers, there were relatively fewer research studies conducted on this group. On the other hand, business travelers accounted for a smaller volume of travel but had a higher proportion of research publications. The study also highlighted a gap in research on vulnerable travelers, despite their higher risk of morbidity and mortality. The authors emphasize the need for more research to guide healthcare interventions for different types of travelers. [Extracted from the article]
