Impetigo is a common skin infection occurring mostly in children from pre-school to school-age. It produces sores and blisters on the hands, neck face and diaper area. A child is more likely to have impetigo if the skin is already affected by other skin problems like poison ivy, eczema, cuts or scrapes and insect bites. http://blog.drsundardas.com/are-allergiesfood-sensitivitities-affecting-your-child/
