This epidemiological survey was undertaken to estimate the annual burden of hospitalizations for pertussis in Spain during a four-year period 1995-1998. Data were obtained from the national surveillance system for hospital data. All hospital discharges for pertussis (ICD-9- CM 033) were analyzed. The annual incidence of hospitalization for pertussis was 1.7 per 100,000 population. Eighty-nine percent of the cases were < 1 year of age (incidence of 78 per 100,000) and 95% were < or =5 years of age (incidence of 28 per 100,000). During the study period, 14 deaths were reported among patients hospitalized by pertussis. Despite of the high immunization rates, many pertussis cases occur each year, mostly of them among very young children.
此次流行病学调查旨在估算1995年至1998年这四年间西班牙百日咳住院治疗的年度负担。数据来自国家医院数据监测系统。对所有因百日咳（国际疾病分类第九版临床修订本，ICD-9-CM 033）导致的医院出院病例进行了分析。百日咳住院治疗的年发病率为每10万人中有1.7例。89%的病例年龄小于1岁（发病率为每10万人中有78例），95%的病例年龄小于或等于5岁（发病率为每10万人中有28例）。在研究期间，有14例因百日咳住院的患者死亡。尽管免疫接种率很高，但每年仍有许多百日咳病例发生，其中大多数发生在幼儿中。
