Participants were enrolled at time of their pre-travel visit at Mahidol University, Bangkok, Thailand. Travelers were prospectively followed by self-administered questionnaires 2 weeks after arrival, upon return to their home country and 2 weeks after return.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>During January 2018\u2013February 2019, 359 travelers were enrolled in Bangkok, Thailand, and the first questionnaire was administered. Follow-up questionnaires were returned by 191, 96 and 64 participants 2 weeks later, at the end of the trip and 2 weeks after return, respectively. A total of 6094 travel days were included in the final analysis. The incidence of acute diarrhea per month per 1000 travelers was 217 [95% confidence interval (CI), 189\u2013248] episodes; skin problems, 197 (95% CI, 170\u2013227); respiratory symptoms, 133 (95% CI, 111\u2013158); fever, 49 (95% CI, 36\u201365); and potential rabies exposure, 34 (95% CI, 24\u201348). The incidence of acute diarrhea episodes per month per 1000 travelers was significantly higher during the first 2 weeks of travel compared with subsequent weeks of travel: 325 (95% CI, 291\u2013362) vs 132 (95% CI, 110\u20131157) (P\u00a0&lt;\u20090.05). The incidence of outpatient visits and hospitalizations per month per 1000 travelers was 49 (95% CI, 36\u201365) and 5 (95% CI, 2\u201310), respectively.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>In this prospective cohort study we observed substantial burden of acute diarrhea and skin and respiratory symptoms among travelers to Southeast Asia.
