title: The head louse in Sierra Leone: an epidemiological study among school children, in the Njala area.
abstract: A survey of five primary schools in the Njala area, Sierra Leone showed that Pediculus humanus capitis infestation is wide-spread. The overall prevalence was 6.8% among 1007 school children examined. Infestation rates varied between schools from 1.4% to 14.6% and the prevalence of infestation increased with age, from 3.1% among class I children to 10.2% among class IV and decreased to 4.9% among class VI children. Females had a higher infestation rate (8.3%) than their male counterparts (5.4%). The infestation rate was higher' in children whose fathers were Farmers (9.4%) followed by Traders (7.8%), Artisans (6.5%) and Professionals who had the lowest infestation rate of (5.8%). Sharing of beds, beddings and combs had a significant effect (P < 0.01) on the rate of infestation. The infestation was light, therefore, impetigo was minimal. Overcrowding at home is the main factor facilitating the transmission of the infestation from one head to another among these children.
