Travelers, particularly those whose tastes or occupations lead to deviation from the usual tourist routes, are at a small but significant risk of acquiring certain diseases they would be unlikely to encounter had they remained in the continental United States. Many of these infections can be rendered unlikely even for the most adventuresome traveler through the appropriate use of immunization and chemoprophylaxis. Other infections are currently unpreventable and the physician's responsibility lies in their premorbid detection.
旅行者，尤其是那些因个人喜好或职业而偏离常规旅游路线的人，感染某些疾病的风险虽小但却显著，而如果他们一直待在美国本土，就不太可能接触到这些疾病。通过适当使用免疫接种和化学预防措施，即使是最具冒险精神的旅行者也能降低感染许多此类疾病的可能性。还有一些感染目前无法预防，医生的职责在于对其进行病前检测。
