Dengue is endemic in the U.S. Virgin Islands, but no outbreaks have been reported since 2005. In November 2012, a school nurse in St. Croix reported suspected dengue in 27 (7%) of 369 students and staff members to the Virgin Islands Department of Health (VIDOH) and the CDC Dengue Branch in Puerto Rico. Four of 12 patient specimens sent to the CDC Dengue Branch for diagnostic testing were confirmed as dengue. Although VIDOH had observed an increase in passive dengue reporting, reliable baseline case counts were unavailable for comparison. An investigation was begun to determine the incidence of recent dengue virus (DENV) infection in schools and islandwide.
登革热在美国维尔京群岛流行，但自 2005 年以来没有报告过暴发疫情。2012 年 11 月，圣克罗伊岛的一名学校护士向美属维尔京群岛卫生部（VIDOH）和波多黎各的疾病预防控制中心登革热分部报告了 369 名学生和教职员工中疑似登革热的 27 例（7%）。送往疾病预防控制中心登革热分部进行诊断检测的 12 份患者标本中有 4 份被确认为登革热。尽管 VIDOH 已经注意到被动登革热报告有所增加，但缺乏可靠的基线病例数进行比较。因此，开始进行调查以确定学校和全岛近期登革热病毒（DENV）感染的发病率。
