A cross sectional study was carried out (impetigo cases n=265, relative prevalence 5.3%, among 50,237 outpatients). Males predominated in childhood, adulthood and overall (OR 2.0) and exhibited a more protracted susceptibility. Impetigo was more prevalent in summer months. Lesions were located on the head and neck (65.4%), followed by 19.6% on an upper extremity and by 7.5% each on the trunk and a lower extremity.
