Surveys were conducted in one urban and two rural regions of the United Republic of Cameroon to estimate the annual incidence of paralytic poliomyelitis. Three different survey methods were used: a review of hospital and clinic registers, a school survey, and a house-to-house survey. The house-to-house survey identified the highest number of lame children and gave estimates of incidence of between 18.8 and 32.6 per 100 000 population in the three regions. The estimates of incidence obtained by the two other survey methods in the urban region did not differ significantly from that obtained by house-to-house survey but, in the rural regions, were significantly lower. It is concluded that house-to-house surveys are a sensitive method of identifying lame children in both urban and rural regions. School surveys and review of hospital and clinic registers, while equally sensitive in urban regions, are less sensitive in rural regions and may significantly underestimate the annual incidence of paralytic poliomyelitis. These limitations should be borne in mind when using the survey methods.
在喀麦隆联合共和国的一个城市地区和两个农村地区进行了调查，以估计麻痹性脊髓灰质炎的年发病率。采用了三种不同的调查方法：查阅医院和诊所登记册、学校调查和挨家挨户调查。挨家挨户调查发现的跛足儿童数量最多，估计三个地区每10万人口中的发病率在18.8至32.6之间。通过其他两种调查方法在城市地区获得的发病率估计值与挨家挨户调查获得的结果没有显著差异，但在农村地区则显著较低。得出的结论是，挨家挨户调查是在城市和农村地区识别跛足儿童的一种敏感方法。学校调查以及查阅医院和诊所登记册，虽然在城市地区同样敏感，但在农村地区较不敏感，可能会显著低估麻痹性脊髓灰质炎的年发病率。在使用这些调查方法时应牢记这些局限性。
