ABSTRACT
Impetigo is one of the most frequently encountered dermatologic condition, in children [Tunnessen, 1985]. A control study was undertaken to investigate some of the ecological factors, clinical manifestations and complications of Impetigo. Three hundred-seventy patients were studied. The controls children are one hundred eighty-six. Most patients were from Cairo and their age was below 6 years., the females formed a slightly higher proportion of the cases than males. Comparison between cases and controls in the socioeconomic state, presence of ecological factors helping the presence and spread of impetigo between infant and preschool children were studied. There was a strong relation between the presence of scabies, pediculosis capitis, insect bites, itching skin conditions and the occurrence of disease. The results suggested that impetigo as an infectious disease may spread from patients with active lesions to siblings or others in close contact. The results of the study concerning complications revealed that most of the complications occurred with non bullous type, while most of bullous impetigo cases had no complication. Non suppurative complication in the form of Kidney trouble did not occur in any of the different clinical types
