Impetigo is a highly contagious skin infection that is caused by bacteria, most commonly Streptococcus pyogenes and Staphylococcus aureus. It is most commonly seen in children, but can affect people of any age. It is characterized by red sores that may appear on any part of the body, including the face, arms, and legs. These sores can be painful and itchy, and can develop into larger blisters that can burst and ooze fluid. Impetigo is typically treated with antibiotics, but it can also be treated with topical creams and ointments.
Symptoms of Impetigo
The most common symptom of impetigo is a red sore that may appear anywhere on the body, but is most commonly seen on the face, arms, and legs. These sores may be itchy and can develop into larger blisters that can burst and ooze fluid. Other symptoms of impetigo may include redness, swelling, and pain in the affected area.
Causes of Impetigo
Impetigo is caused by bacteria, most commonly Streptococcus pyogenes and Staphylococcus aureus. These bacteria can enter the body through cuts or other skin abrasions and can spread through contact with an infected person or object.
Diagnosis of Impetigo
To diagnose impetigo, a doctor will usually take a sample of the fluid from the blisters and send it to a lab for testing. The doctor may also perform a physical examination to look for signs of infection.
Treatment of Impetigo
Impetigo is typically treated with antibiotics, either orally or topically. Topical treatments may include creams or ointments that contain antibiotics. In some cases, a doctor may also recommend a medicated ointment that can help to soothe the affected area and reduce itching. In more severe cases of impetigo, a doctor may prescribe oral antibiotics.
