Impetigo is a bacterial skin infection most commonly found in children and caused primarily by staph and/or strep. It is very contagious and spread by touching, rubbing or scratching the sores, and by coming into contact with contaminated objects such as towels and bedding. The sores will often blister, then pop and ooze serum, which frequently dries into a honey-colored crust (see photo). Impetigo is frequently mistaken for ringworm (fungal skin infection). If left untreated, strep impetigo can lead to kidney damage, mostly in children less than 6 years of age. Blood in the urine (hematuria) and facial, hand and/or feet swelling (edema) following a suspicious rash indicates this potentially serious condition. Treatment of impetigo, and prevention of this complication, usually involves oral antibiotics. Sometimes, Bactroban ointment is used in mild cases…..Richard R Samuel, MD Family Practice and Urgent Care Hayden, ID USA
