Recent surveys of lameness attributable to poliomyelitis in several African countries have revealed rates of residual paralysis of two to 11 per 1,000 children, a prevalence implying annual incidence rates for poliomyelitis of 10-55 cases per 100,000 population. Factors responsible for this high incidence are the unsanitary conditions present in many African communities, especially rural and periurban areas. Whereas poliomyelitis is endemic in Africa and paralysis occurs early in childhood, the apprehension and alarm that is evident in the developed world is almost absent in Africa. Hence, the administrative and economic resources for massive programs of poliomyelitis vaccination are lacking. Lameness prevalence rates of 2.6 per 1,000 children in certain areas of Africa illustrate that the programs of immunization against poliomyelitis should be intensified.
近期对几个非洲国家小儿麻痹症所致跛足情况的调查显示，每1000名儿童中残留麻痹的发生率为2至11例，这一流行率意味着小儿麻痹症的年发病率为每10万人口10 - 55例。造成这种高发病率的因素是许多非洲社区，尤其是农村和城市周边地区存在的不卫生状况。小儿麻痹症在非洲呈地方病状态，且麻痹在儿童早期就会出现，而在发达国家明显存在的担忧和恐慌在非洲几乎不存在。因此，缺乏开展大规模小儿麻痹症疫苗接种计划所需的行政和经济资源。非洲某些地区每1000名儿童中有2.6例跛足流行率表明，应该加强小儿麻痹症免疫计划。
