Since 1986, two human tickborne diseases caused by Ehrlichia spp. have been recognized in the United States: human monocytic ehrlichiosis (HME), caused by E. chaffeensis, and human granulocytic ehrlichiosis (HGE), caused by an agent closely related to E. equi (1,2). In June 1995, the Westchester County (New York) Department of Health (WCDOH) received reports from physicians who were treating patients for suspected HGE. In response, the WCDOH sent information to all primary-care physicians in Westchester County describing the clinical and laboratory features of ehrlichiosis (fever, myalgia, headache, leukopenia, and thrombocytopenia) and requested that they voluntarily report suspected cases of ehrlichiosis. This report summarizes an investigation by the New York State Department of Health (NYSDOH) and the WCDOH of suspected ehrlichiosis cases and the clinical characteristics of confirmed and probable cases.
自1986年以来，美国已确认两种由埃立克体属细菌引起的人蜱传疾病：由查菲埃立克体引起的人单核细胞埃立克体病（HME），以及由一种与马埃立克体密切相关的病原体引起的人粒细胞埃立克体病（HGE）(1,2)。1995年6月，纽约州韦斯特切斯特县卫生部（WCDOH）收到了治疗疑似HGE患者的医生的报告。作为回应，WCDOH向韦斯特切斯特县的所有初级保健医生发送了信息，描述了埃立克体病的临床和实验室特征（发热、肌痛、头痛、白细胞减少和血小板减少），并要求他们自愿报告疑似埃立克体病病例。本报告总结了纽约州卫生部（NYSDOH）和WCDOH对疑似埃立克体病病例的调查以及确诊和可能病例的临床特征。
