Impetigo is a contagious, bacterial skin infection that is commonly diagnosed in young children and primarily affects the face and neck. It usually presents with blistered or crusted-over red sores around the mouth and nose. The bacteria that causes impetigo is resistant to certain antibiotics and requires a skilled physician to determine the right type of medication for treating it. It’s important to seek medical attention for this problem because serious complications can result from leaving it untreated. Impetigo can be spread by skin-to-skin contact or by touching a surface or object that has come into contact with the bacteria. Children are often exposed to it at playgrounds and day care centers.
