Pediculosis capitis is still a world-wide public health problem. Pediculus humanos capitis, the agent, is a permanent and specific human blood-sucking ectoparasite extended throughout the world. By the end of sixties and begin of seventies an important increase of prevalence of this parasitose was observed in many countries and lice infestation throughout the world was estimated to run into hundreds of millions. Decline of personal hygiene, increased promiscuity and long hairstyle, particularly in adolescents and young people seemed to mark the beginning of this new situation. At present pediculosis capitis not only affects low socio-economic groups, but middle and high level groups. Several observations have shown a alear relationship between long hair and pediculosis capitis. Prevention of pediculosis capitis is supported by community health education, stressing the personal hygiene, the use of reasonable short hair and frequent washing of head

Of 1000 pupils examined by visual inspection for head lice in four large primary schools of contrasting socioeconomic environment in Baghdad, 12,2% were found to be infested, with infestation rates being higher in the schools of lower socioeconomic status. Over all, girls appeared to have a significant higher infestation rates than boys [54.8% vs3l.8%], Younger pupils [6-8yr] had significantly lower infestation rate [33.8%] than older ones [49%].

This survey seeks to estimate the prevalence of infestation in pupils. of four large primary schools of contrasting social status in Baghdad city with the following aims: [1] To determine the infestation levels in these schools. [2] To determine how far the prevalence can be correlated with Socioeconomic background, sex and age
