A prospective population-based surveillance system was established to characterize the epidemiology of cat-scratch disease (CSD) among residents of Connecticut who were reported to the state health department with a diagnosis of suspected CSD. During 1992 and 1993, 246 persons met the case definition, for an average statewide annual incidence of 3.7/100,000 persons. The median age of patients with CSD was 14 years (range, 1-64), and 52% were female. The age-specific attack rate was highest among persons < 10 years of age (9.3/100,000) and decreased with increasing age. Symptoms in addition to adenopathy were noted by 74% of case-patients. Eleven percent of all case-patients were hospitalized. There were no deaths. Most patients with clinically diagnosed CSD developed an immunologic response to Bartonella species. Our data suggest that although CSD is primarily a disease of younger persons, the age spectrum is wider than was commonly appreciated.
建立了一个基于人群的前瞻性监测系统，以描述向康涅狄格州卫生部门报告疑似猫抓病（CSD）诊断的该州居民中猫抓病的流行病学特征。在1992年和1993年期间，246人符合病例定义，全州平均年发病率为3.7/10万人口。猫抓病患者的年龄中位数为14岁（范围为1至64岁），52%为女性。年龄别发病率在<10岁的人群中最高（9.3/10万），并随年龄增长而下降。74%的病例患者除淋巴结病外还出现了其他症状。所有病例患者中有11%住院治疗。无死亡病例。大多数临床诊断为猫抓病的患者对巴尔通体属产生了免疫反应。我们的数据表明，虽然猫抓病主要是一种年轻人的疾病，但年龄范围比通常认为的更广。
