In October 2010, a Nebraska clinician notified the state's Central District Health Department (CDHD) of a cluster of dengue-like illnesses in six of 28 missionary workers from Nebraska and Georgia who recently had returned after 7-11 days in Haiti. Infection with the mosquito-transmitted dengue virus (DENV) later was confirmed by laboratory testing in seven persons, five of whom were hospitalized. CDHD, the Nebraska Department of Health and Human Services (NDHHS), the Georgia Department of Public Health (GDPH), and CDC conducted a retrospective cohort study to assess the pretravel dengue knowledge and mosquito-avoidance practices of those with and without laboratory-confirmed infection. This report describes the results of that study, which indicated that 90% of those in the study had a pretravel health-care appointment, 57% sought travel advice on the Internet, and 24% used mosquito repellent several times a day; neither pretravel knowledge nor mosquito-avoidance practices were significantly associated with absence of DENV infection. Clinicians should be vigilant for dengue among travelers returning from Haiti and other areas where DENV is endemic or likely to be endemic and should report suspected cases of dengue to public health authorities.
2010 年 10 月，内布拉斯加州的一位临床医生向该州中部地区卫生部门（CDHD）报告了一个聚集性登革热样疾病的病例，该病例涉及来自内布拉斯加州和佐治亚州的 28 名传教士工作人员中的 6 人，他们在海地停留了 7-11 天后刚刚返回。随后，实验室检测确认了七人感染了蚊媒传播的登革热病毒（DENV），其中五人住院治疗。CDHD、内布拉斯加州卫生和人类服务部（NDHHS）、佐治亚州公共卫生部（GDPH）和 CDC 开展了一项回顾性队列研究，以评估有和没有实验室确诊感染的人的旅行前登革热知识和蚊虫预防措施。本报告介绍了该研究的结果，结果表明，研究中的 90%的人在旅行前进行了医疗保健预约，57%的人在网上寻求旅行建议，24%的人每天多次使用驱蚊剂；旅行前的知识和蚊虫预防措施与 DENV 感染的不存在均无显著相关性。临床医生应该警惕从海地和其他登革热流行或可能流行的地区返回的旅行者中的登革热，并向公共卫生当局报告疑似登革热病例。
