Prevalence of Pediculus humanus capitis Infestation and Socio-Economic Status in School Children: A Review

The human head louse, Pediculus humanus capitis, represents a universal health problem for children and families worldwide. Head lice infestation is a general problem affecting children between 5 and 13 years of age, causing anxiety, depression, and disruption to schooling. The prevalence of this ectoparasitic infestation varies significantly across regions and socio-economic groups. This problem is more common in poor countries, highly populated areas, and regions with limited awareness of personal hygiene and inadequate health facilities. Managing head lice requires coordinated public health efforts targeting all persons at risk, particularly school-aged children from disadvantaged socio-economic backgrounds.
