What should you know about impetigo staphylococcus aureus?

Staphylococcus aureus can live on skin without causing illness, but it may cause a surface infection when the protective barrier is disrupted by a scratch, insect bite, eczema flare, or other irritation. The resulting lesions can be itchy and may spread through scratching or contact with fluid from a sore. The same visible pattern can have different causes, so a clinician may assess the skin rather than relying on the name of one bacterium.

People with Atopic Dermatitis may have a weaker skin barrier and can develop crusting when irritated skin becomes infected. This does not mean every crusted eczema patch is impetigo.

Wash hands regularly, keep sores covered with a clean dressing when practical, and avoid sharing towels, razors, clothing, or bedding. Clean the skin gently and avoid squeezing lesions. Follow the prescribed course if a clinician recommends Antibiotics For Skin Infection; a small, localised area may be managed with Topical Antibiotic Therapy when appropriate.

Seek medical advice if sores multiply, redness extends beyond the original area, pain or swelling increases, or treatment does not produce the expected improvement. Get prompt help for fever, unusual weakness, rapidly spreading redness, facial swelling, or sores close to the eye. A clinician may reconsider the diagnosis or treatment if the pattern changes.

Ask whether the appearance suggests impetigo, whether a sample is needed, how to protect household members, and which treatment should be used for the number and location of sores.
