Impetigo is a skin infection typically caused by one of two bacteria: group A streptococcus or staphylococcus aureus. These types of bacteria are normally found on a healthy person. When you get a cut or a scratch these bacteria can enter the wound and cause impetigo.

The rash usually starts as a small red bump and it turns into a blister. The blisters break easily and leave a honey colored crust. The rash is usually very itchy. Impetigo is more common among children. It is very contagious and is spread by touching other people who have it. Impetigo can affect any part of the body, but the most common places are the nose and mouth. It is more likely to show up on skin that is already irritated from things like eczema, poison ivy, or insect bites.

Diagnosis is based on the appearance of the rash. Your provider may treat it with a topical or oral antibi- otic depending on the severity of the rash. It is important to keep the sores covered since it is very contagious. After 3 days of treatment the rash should start to heal and scab over. If your skin does not begin to heal or symptoms worsen, you need to call your physician.

In addition to the medications that you are prescribed, you can gently wash the affected areas with warm water and unscented soap. To avoid spreading impetigo you can cover the areas with gauze or a loose bandage.

It is important not to scratch, and keep your fingernails cut short to keep down the spread of the infection. The best way to prevent impetigo is to follow good hygiene practices.
