Common bacteria, some of which are found normally on the skin, cause impetigo. When the bacteria enter an open area in the skin, the infection can occur. Staphylococcus aureus Impetigo is more common in children than adults, but adults may also have the infection. Impetigo is made worse by poor hygiene and warm temperatures. Impetigo usually occurs on the face, neck, arms, and limbs, but the lesions may appear on any part of the body.
Impetigo starts as a small vesicle, or fluid-filled lesion.
The lesion then ruptures and the fluid drains leaving areas that are covered with the honey-colored crusts. The lesions may all look different, with different sizes and shapes. The lymph nodes become enlarged when your child s body is fighting an infection. The symptoms of impetigo may resemble other skin conditions. Always consult your child's physician for a diagnosis.
