An analysis was made of the severity of over 8000 cases of whooping cough notified from October 1974 to March 1975. Ten per cent of these patients were admitted to hospital and there were 10 deaths. Severity was directly related to age, the disease being most severe in children under 1 year, especially those under 6 months. There was some evidence that previous vaccination reduced the severity of the disease, but the vaccination programme does not cover very young children, and for them whooping cough is a dangerous disease.
对1974年10月至1975年3月期间报告的8000多例百日咳病例的严重程度进行了分析。其中10%的患者住院治疗,并有10例死亡。严重程度与年龄直接相关,该病在1岁以下儿童中最为严重,尤其是6个月以下的儿童。有证据表明,先前的疫苗接种可降低疾病的严重程度,但疫苗接种计划并未覆盖非常年幼的儿童,对他们来说,百日咳是一种危险的疾病。
