旅行医学研究的内容应以疾病的预防与监测(尤其是传染病监测)为主要方面。由于某些传染病有较长的潜伏期,通过返程后的监测,可了解旅行者疾病感染和传播途径以及旅行中存在哪些有碍健康的因素,掌握信息与数据。从某种意义上说,旅行返程后的监测与追踪,是继续运用实验医学、临床医学与流行病学方法深入病因探索,进行预防措施效果 The content of travel medical research should focus on disease prevention and surveillance (especially infectious disease surveillance). Because some infectious diseases have a long incubation period, post-return surveillance can help understand travelers’ pathways of infection and transmission, and what health-impelling factors and information and data are in travel. In a sense, the monitoring and follow-up after the return trip is to continue using the methods of experimental medicine, clinical medicine and epidemiology to probe into the causes and carry out preventive measures
