The prevalence of asthma in a small African town has been assessed using two questionnaires. The first was put to 9768 subjects aged 5 years and older and the second, more detailed, questionnaire to random selections of these subjects grouped according to their replies. The overall prevalence of asthma was 1.40%. In those under 20 years of age it was 1.20% and in adults, 1.57%. This adult rate is similar to those in developed countries but that in children is lower. The relative paucity of childhood asthma is compatible with the suggestion that infestation with parasites may protect against the disease.
在一个非洲小镇，通过两份调查问卷评估了哮喘的患病率。第一份问卷发放给了9768名5岁及以上的受试者，第二份更详细的问卷则随机发放给根据第一份问卷回答情况分组的受试者。哮喘的总体患病率为1.40%。20岁以下人群的患病率为1.20%，成年人的患病率为1.57%。成年人的患病率与发达国家相似，但儿童的患病率较低。儿童哮喘相对较少这一情况与寄生虫感染可能预防该疾病的观点相符。
