The prevalence of head lice (Pediculus humanus capitis) was investigated among urban and rural schoolchildren in Ibadan City and three surrounding villages all in Southern Nigeria. 106 (5.7%) of 1860 urban schoolchildren examined were infested compared with only seven (1.5%) of 473 children from rural schools (P less than 0.05). Pediculosis appears to be an urban problem which may be associated with overcrowding. However, the intensity of head louse infestation was low among the urban schoolchildren with 74.6% of all lousy children harbouring one to five lice per head and only 6.0% with more than 30 lice per head.
在尼日利亚南部伊巴丹市及周边三个村庄的城乡学童中，对人头虱（人头虱属）的感染率进行了调查。在接受检查的1860名城市学童中，有106名（5.7%）受到感染，而来自农村学校的473名儿童中只有7名（1.5%）受到感染（P小于0.05）。头虱病似乎是一个城市问题，可能与过度拥挤有关。然而，城市学童中的头虱感染强度较低，所有感染头虱的儿童中，74.6%的人每头有1至5只虱子，只有6.0%的人每头有超过30只虱子。
