We identified all 391 cases of meningitis hospitalized in a metropolitan community (population 367,094) over a four-year period to assess incidence, morbidity, and mortality. The crude incidence rate was 27 per 100,000 person years; the incidence rate for children under 5 years of age was 174 per 100,000 person years. The case fatality rate was 3 per cent. Bacterial organisms were identified in 33 per cent of all cases, with H. influenzae most commonly observed (53 per cent). Only 16 per cent of hospitalized cases were known to the county health department.
我们确定了在一个大都市社区（人口367,094）四年期间住院的所有391例脑膜炎病例，以评估发病率、发病率和死亡率。粗发病率为每10万人年27例；5岁以下儿童的发病率为每10万人年174例。病死率为3%。在所有病例的33%中鉴定出细菌病原体，其中最常见的是流感嗜血杆菌（53%）。县卫生部门仅知晓16%的住院病例。
