Skin diseases are commonly observed in the general population of developing countries. They are a major cause of morbidity in children and their complications can be severe. The understanding of the epidemiology and health importance of skin diseases remain largely unknown, however determination of such data will be important for developing health strategies for their prevention and treatment. This study was undertaken to determine the prevalence and spectrum of skin diseases in school aged children in Jos North LGA of Plateau State. It also aims at determining possible predisposing factors to acquiring skin diseases and the quality of life of children affected by these diseases. The subjects consisted of children aged 6 to 12 years. Pupils from public and private schools from 5 out of the 20 wards in Jos North LGA were recruited for the study. Following endorsement of written informed consent, the eligible study subjects were interviewed and then examined clinically. Information and dermatologic findings were recorded for each respondent and subsequently transferred into a computer using software SPSS versions 17.0 and then analyzed at the end of the study. Of a total of 390 subjects recruited in this study, 141 (36.2%) had skin diseases. There were 28 different types of skin diseases observed in the affected children, with more than a quarter of them (28.4%) having more than a single skin disease. Infectious skin diseases accounted for the largest group seen (46.7%) followed by dermatitis (25.3%). Overall the commonest diseases seen were tinea (11.3%), seborrheic dermatitis (4.9%), furuncles(3.3%), folliculitis (2.8%), acne(2.8%), scars(2.8%), papular urticaria(2.6%), postinflammatory hyperpigmentation(2.6%), atopic dermatitis(2.3%) and alopecia(1.3%).
