Two surveillance systems were initiated in Texas in 1980 to detect cases of dengue fever. Physicians throughout the state were requested to report cases of dengue (passive surveillance), and 27 out-patient facilities serving geographically and ethnically high risk populations were asked to report cases of dengue-like illness weekly (active surveillance). Additionally, two clinics participating in active surveillance submitted acute-phase blood specimens weekly for dengue virus isolation. Sixty-three cases of illness due to dengue type 1 infection (dates of onset 2 August-10 November) were documented by virus isolation or serologic testing; 52 of them (83%) occurred n countries adjacent to the Texas-Mexico border. Fifty-six patients (89%) were Hispanic; 46 (73%) were females. Twenty-seven patients (43%) had not traveled outside the U.S. before becoming ill. Since no clinically apparent outbreak of dengue was ever recognized by public health officials in Texas in 1980, the active surveillance system in other Gulf Coast states should be considered when the risk of introduction of dengue is considered high.
1980年在得克萨斯州启动了两个监测系统以发现登革热病例。要求该州各地的医生报告登革热病例(被动监测),并要求27个为地理和种族高危人群服务的门诊设施每周报告登革热样疾病病例(主动监测)。此外,参与主动监测的两家诊所每周提交急性期血液标本用于登革热病毒分离。通过病毒分离或血清学检测记录了63例由1型登革热感染引起的疾病(发病日期为8月2日至11月10日);其中52例(83%)发生在得克萨斯州与墨西哥边境相邻的国家。56名患者(89%)为西班牙裔;46名(73%)为女性。27名患者(43%)在患病前未曾出过美国。由于1980年得克萨斯州的公共卫生官员从未确认有临床上明显的登革热疫情爆发,当认为登革热传入风险较高时,应考虑在其他墨西哥湾沿岸州建立主动监测系统。
