Impetigo is a common skin infection.
Causes, incidence, and risk factors
Impetigo is caused by streptococcus (strep) or staphylococcus (staph) bacteria. Methicillin-resistant staph aureus (MRSA) is becoming a common cause.
The skin normally has many types of bacteria on it, but intact skin is an effective barrier that keeps bacteria from entering and growing in the body. When there is a break in the skin, bacteria can enter the body and grow there, causing inflammation and infection. Breaks in the skin may occur with:
Animal bites
Human bites
Injury or trauma to the skin
Insect bites
Impetigo may also occur on skin where there is no visible break. It is most common in children, particularly those in unhealthy living conditions. In adults, it may follow other skin disorders or a recent upper respiratory infection such as a cold or other virus. It is similar to cellulitis, but it only involves the top layers of the skin. Impetigo is contagious, meaning it can spread to others. You can catch this infection if the fluid that oozes from the blisters touches an open area on your skin.
Symptoms
A single or possibly many blisters filled with pus; easy to pop and when broken -- leave a reddish raw-looking base (in infants)
Itching blister: Filled with yellow or honey-colored fluid
Itching blister: Filled with yellow or honey-colored fluid
Oozing and crusting overRash may begin as a single spot, but if person scratches, it may spread to other areas
Skin lesions on the face, lips, arms, or legs, that spread to other areas
Swollen lymph nodes near the infection (lymphadenopathy)
Signs and tests
Diagnosis is based mainly on the appearance of the skin lesion.
A culture of the skin or lesion usually grows the bacteria streptococcus or staphylococcus. The culture can help determine if MRSA is the cause, because specific antibiotics are used to treat this infection.
Treatment
The goal is to cure the infection and relieve the symptoms. A mild infection may be treated with a prescription antibacterial cream. More severe cases may require antibiotics, taken by mouth. Wash (do not scrub) the skin several times a day, preferably with an antibacterial soap, to remove crusts and drainage.
Expectations (prognosis)
The sores of impetigo heal slowly and seldom scar. The cure rate is extremely high, but the condition often comes back in young children.
Complications
Kidney failure (post-streptococcal glomerulonephritis) (rare)
Many patches of impetigo (in children)
Permanent skin damage and scarring (very rare)
Spread of the infection to other parts of the body (common)
Calling your health care provider
Call for an appointment with your health care provider if you have symptoms of impetigo.
Prevention
Prevent the spread of infection. If you have impetigo, always use a clean washcloth and towel each time. Do not share towels, clothing, razors, and and other personal care products with other family members. Wash your hands thoroughly after touching the skin lesions.Good general health and hygiene help to prevent infection. Thoroughly clean minor cuts and scrapes with soap and clean water. You can also use a mild antibacterial soap. Impetigo is contagious, so avoid touching the draining (oozing) lesions.
