Staph infections are caused by Staphylococcus aureus bacteria, which normally live harmlessly on the skin. When they get into the body through a cut or wound, they can cause infections ranging from mild skin problems to more serious illness.
Common Types of Staph Skin Infections
- Impetigo – contagious sores that form a crust, often around the nose and mouth.
- Boils (furuncles) – painful, pus-filled lumps that develop around a hair follicle.
- Carbuncles – clusters of boils that form a connected area of infection.
- Cellulitis – a spreading infection of the deeper skin layers, with redness, swelling and warmth.
- Folliculitis – infection of the hair follicles, appearing as small red bumps.
- Styes – painful lumps along the edge of the eyelid.
- MRSA – the methicillin-resistant strain of S. aureus, which is harder to treat with standard antibiotics.
How Doctors Treat Staph Infections
Treatment is decided by a clinician. Many small skin infections settle with good hygiene and warm compresses. Abscesses often need incision and drainage by a professional. Antibiotics are prescribed when needed — never self-prescribe.
Warning Signs: When to See a Doctor
- Spreading redness or red streaks.
- Fever or severe pain.
