Travelers' diarrhea (TD) is frequently encountered in people traveling from high-income to low-income countries; however, its epidemiology in those traveling between high-income countries is not known.
To evaluate the incidence of diarrhea in North American students relocating to Israel.
A retrospective cohort study involving medical students from the United States and Canada relocating to Israel was conducted. Students who relocated to Israel during 2010-2016 were contacted by email to participate in an anonymous survey. Data included demographic information as well as occurrence, timing, duration, and outcome of diarrhea after relocation.
Ninety-seven students participated in the survey. Most (93.7%) students relocated from the United States or Canada. The period-prevalence of diarrhea was 69.1%. The incidence of diarrhea declined from 34.8 cases per 100 student-months during the first month after relocation to 1.3 cases per 100 student-months after 1 year. The duration of diarrhea was up to 1 week in 72.7%. Students who reported diarrhea were younger than students who did not (mean age 24.0 ± 2.2 and 28.4 ± 1.8 years, respectively, P < 0.001). No other demographic parameter was significantly associated with a higher likelihood of diarrhea.
A high proportion of North American medical students relocating to Israel reported diarrhea with clinical and epidemiological features similar to classic TD. Further studies are needed to elucidate the causative agents of TD in Israel.
旅行者腹泻（TD）在从高收入国家前往低收入国家的旅行者中很常见；然而，其在高收入国家之间旅行者中的流行病学情况尚不清楚。
评估迁往以色列的北美学生腹泻的发生率。
进行了一项回顾性队列研究，纳入了从美国和加拿大迁往以色列的医学生。通过电子邮件联系了2010 - 2016年期间迁往以色列的学生，邀请他们参与一项匿名调查。数据包括人口统计学信息以及搬迁后腹泻的发生情况、时间、持续时间和结局。
97名学生参与了调查。大多数（93.7%）学生从美国或加拿大迁来。腹泻的期间患病率为69.1%。腹泻发生率从搬迁后第一个月的每100学生月34.8例降至1年后的每100学生月1.3例。72.7%的腹泻持续时间长达1周。报告腹泻的学生比未报告腹泻的学生年轻（平均年龄分别为24.0±2.2岁和28.4±1.8岁，P<0.001）。没有其他人口统计学参数与腹泻的较高可能性显著相关。
迁往以色列的北美医学生中，很大一部分报告有腹泻，其临床和流行病学特征与经典TD相似。需要进一步研究以阐明以色列TD的病原体。
