Impetigo
What is Impetigo?
Impetigo is a highly contagious skin infection that is caused by bacteria. It is characterized by red sores or blisters that ooze fluid and form a yellow-brown crust. Impetigo most commonly appears on the face, especially around the mouth, nose and eyes, but it can also develop on other parts of the body. It usually occurs in children, but can affect people of any age.
Symptoms of Impetigo
The most common symptom of impetigo is a group of red sores or blisters, which may be surrounded by red, itchy skin. The sores typically rupture, leaving a yellow-brown crust, and may ooze a pus-like fluid. Other symptoms include:
- Swollen lymph nodes
- Fever
- Headaches
- Fatigue
- Muscle aches
Causes of Impetigo
Impetigo is caused by staphylococcal or streptococcal bacteria, which can enter the body through tiny cuts or insect bites on the skin. Impetigo is highly contagious and can be spread directly through skin-to-skin contact or indirectly through contact with objects such as towels or clothing contaminated with the bacteria.
Treatment of Impetigo
Impetigo is usually treated with a course of antibiotics. Topical ointments or lotions may be prescribed to help reduce pain and itching. In some cases, your doctor may also recommend antihistamines to help reduce itching and swelling. It is important to finish the entire course of antibiotics to ensure that the infection is completely eradicated.
Prevention of Impetigo
The best way to prevent the spread of impetigo is to practice good hygiene. This includes washing your hands frequently with soap and water, avoiding sharing towels or clothing, and keeping any existing skin sores clean and covered with a bandage. If your child has impetigo, it is important to keep them out of school or daycare until the infection has cleared up.
