Impetigo:
Information for adults

Impetigo is very common in children, affecting up to 10% of those who come to a pediatric clinic. Children up to 6 years old are most likely to be infected. It also may occur in adults. Those who live in a warm, humid climate are more often affected. Insect bites, crowded living conditions, and poor skin cleansing make a person prone to infection. It may spread easily through schools and day-care centers. Sports involving skin-to-skin contact, having a weak immune system, or having a chronic skin problem, such as eczema, also increase the chance of getting impetigo. Lesions on the neck and scalp may be associated with head lice.
