Prevalence of head louse (Pediculus capitis) infestation among inhabitants of the Niger Delta.

The prevalence of head louse Pediculus capitis Deg. among inhabitants of the Niger Delta was investigated. 5.7% of 7,360 subjects harboured head lice. The infestation was highest among the 6-13 year age group (13.5%) and decreased progressively with increase in age of the subjects. Overall, more female subjects than male subjects harboured lice. The present study establishes the need for anti-louse campaign in the study area to reduce human sufferings caused by head louse particularly among children of primary and post-primary school age.
