Impetigo

Impetigo is an infection of the top layers of the skin caused by Staphylococcal or Streptococcal bacteria. This infection is common among children and usually occurs when the bacteria get into an existing cut or insect bite.

What are the symptoms of impetigo?

Impetigo is usually found on the face around the nose and mouth but may be anywhere on the body. Impetigo usually starts as small red pimples or fluid filled blisters that eventually break. The blisters then appear as yellow, crusty, or weeping patches on the skin. Itching is common.

How is impetigo spread?

The bacteria that cause impetigo are spread from person to person by either direct contact with the skin lesions of an infected person or indirect contact with surfaces contaminated with the drainage from skin lesions.

The time between exposure to impetigo and development of symptoms (incubation period) is usually 1-3 days.

How is impetigo treated?

The affected area should first be cleaned with soap and water. Usually, it is then recommended to apply an antibiotic cream/ointment. Sometimes an oral antibiotic is prescribed by the doctor.

How can the spread of impetigo be prevented/limited?

A child with possible impetigo should be excluded from school/child care center and evaluated by a doctor for diagnosis and treatment. A child with impetigo should be excluded for 24 hours after starting treatment. Frequent handwashing and avoiding contact with skin lesions will minimize transmission. Additionally towels, bedding and clothing should not be shared. Environmental surfaces and toys should be sanitized on a routine basis.

It is recommended to trim the nails of an infected person to reduce the injury to the infected area while scratching and to prevent subsequent transmission to other parts of the body. If possible, the affected area should be covered with a loose bandage.

In the event of an outbreak (more than one case in a group), please report to KCHD​.
