Is impetigo contagious?
Impetigo is contagious, primarily from direct contact with someone who has it, but sometimes from towels, toys, clothing, or household items. After starting in one location, impetigo often spreads to other parts of the body. This is particularly common with impetigo in children. There may be mini epidemics in day-care centers. Bacteria that cause impetigo may enter through a break in the skin, such as that which comes from cuts and scrapes. A common toddler impetigo experience is the development of impetigo at the nasal openings inflamed by the prominent nasal drainage associated with a cold. In this situation, skin integrity is often disrupted by the continuous covering of purulent nasal discharge. Adults often develop impetigo from close contact with infected children. Heat, humidity, and the presence of eczema predispose a person to developing impetigo. Recurrent impetigo infections may be associated with staph or strep bacteria residing in the nose and spreading from to other parts of the skin.
