The incidence of invasive Haemophilus influenzae infections was studied among all residents of Rochester, Minnesota, under 20 years of age during the period 1975-1983. The incidence in children under 5 years of age was 115 and 64 cases per 100,000 children per year for all invasive cases and for meningitis, respectively. These rates are among the highest reported for an essentially all-Caucasian population in the United States, while the ratio of meningitis to non-meningitis cases (1.1:1) is among the lowest. This suggests possible under-ascertainment of non-meningitis cases in previous US studies of Haemophilus influenzae infections.
1975年至1983年期间，对明尼苏达州罗切斯特市所有20岁以下居民中的侵袭性流感嗜血杆菌感染发病率进行了研究。5岁以下儿童中，所有侵袭性病例和脑膜炎病例的发病率分别为每年每10万名儿童115例和64例。在美国，这些发病率在基本为白种人的人群中是报告的最高发病率之一，而脑膜炎病例与非脑膜炎病例的比例（1.1:1）则是最低的之一。这表明在美国先前关于流感嗜血杆菌感染的研究中，非脑膜炎病例可能存在漏报情况。
