Dengue is a mosquito-transmitted acute viral illness caused by any of the four dengue virus serotypes (DEN-1, DEN-2, DEN-3, and DEN-4). Dengue is endemic in most tropical and subtropical areas of the world and has occurred among U.S. residents returning from travel to such areas. CDC maintains a laboratory-based passive surveillance system for imported dengue among U.S. residents (laboratory-diagnosed dengue in a U.S. resident living in an area without known authochthonous dengue transmission, with travel history outside the United States in the 14 days before symptom onset). The system relies on reports by clinicians to state health departments, which forward patient specimens to CDC for diagnostic testing. This report summarizes information about imported dengue cases among U.S. residents during 1999-2000. The findings indicate that dengue continues to cause disease in U.S. travelers abroad. Travelers to tropical areas should protect themselves from mosquito bites, and health-care providers should consider dengue in the differential diagnosis of illness for patients who have returned recently from such areas.
登革热是一种由四种登革热病毒血清型（DEN-1、DEN-2、DEN-3和DEN-4）中的任何一种引起的经蚊子传播的急性病毒性疾病。登革热在世界上大多数热带和亚热带地区流行，在美国从这些地区旅行归来的居民中也有发生。美国疾病控制与预防中心（CDC）维持着一个针对美国居民输入性登革热的基于实验室的被动监测系统（对居住在无本地登革热传播已知地区的美国居民进行实验室诊断的登革热，其在症状出现前14天内有美国境外旅行史）。该系统依靠临床医生向州卫生部门报告，州卫生部门将患者标本送交美国疾病控制与预防中心进行诊断检测。本报告总结了1999 - 2000年期间美国居民输入性登革热病例的信息。研究结果表明，登革热继续在美国出国旅行者中引发疾病。前往热带地区的旅行者应防止被蚊子叮咬，医疗保健人员在对近期从这些地区归来的患者进行疾病鉴别诊断时应考虑登革热。
