hi, Tretment:For generations, the disease was treated with an application of the antiseptic gentian violet.Today, topical or oral antibiotics are usually prescribed. Treatment may involve washing with soap and water and letting the impetigo dry in the air. Mild cases may be treated with bactericidal ointment, such as mupirocin, which in some countries may be available over-the-counter. More severe cases require oral antibiotics, such as dicloxacillin, flucloxacillin or erythromycin. Alternatively amoxicillin combined with clavulanate potassium, cephalosporins (1st generation) and many others may also be used as an antibiotic treatment. Prevention:Keeping the skin clean is the best way to keep it healthy. Treat cuts, scrapes, insect bites and other wounds right away by washing the affected areas.If someone in your family already has impetigo, take these measures to help keep the infection from spreading to others: Gently wash the affected areas with mild soap and running water and then cover lightly with gauze. Wash an infected person s clothes, linens and towels every day and don t share them with anyone else in your family. Wear gloves when applying any antibiotic ointment and wash your hands thoroughly afterward. Cut an infected child s nails short to prevent damage from scratching. Wash hands frequently. Keep your child home until your doctor says he or she isn t contagious. thank you hope this information might help you.
