- Tiny pimples or red areas quickly turn into oozing honey-colored, crusted patches (usually less than an inch) that spread.
- The face or traumatized areas of the skin are affected.
- There may be some itching or swollen lymph nodes, but the person feels generally well.
- Sometimes deeper pus-filled sores and scabs that leave scars occur.
- Painless blisters (about an inch or less) occur that may break easily.
- These often spread to the face, trunk, arms, or legs.
- The person feels generally well.
Moderate – There are over 10 lesions and several small skin areas are affected.
Severe – There are many lesions, large areas of skin are affected, and/or the person feels ill with fever, diarrhea, or weakness.
For mild infection:
- Gently wash the area with a mild soap and water twice or more daily, and cover with gauze or a non-stick dressing if possible.
- An over-the-counter antibiotic ointment can be applied after washing the skin 3–4 times daily. Wash hands after application or wear gloves to apply.
- To remove crusts, soak with a vinegar solution (1 tablespoon of white vinegar to a pint of water) for 15–20 minutes.
- Wash clothing, towels, and bedding daily and don't share these with others.
- Wash hands frequently, try not to touch the areas, and cut the fingernails.
- Keep a child home until there are no scabs or open areas present.
If you are currently being treated for a skin infection that has not improved after 2–3 days of antibiotics, return to your doctor.
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is a strain of "staph" bacteria resistant to antibiotics in the penicillin family, which have been the cornerstone of antibiotic therapy for staph and skin infections for decades. CA-MRSA previously infected only small segments of the population, such as health care workers and persons using injection drugs. However, CA-MRSA is now a common cause of skin infections in the general population. While CA-MRSA bacteria are resistant to penicillin and penicillin-related antibiotics, most staph infections with CA-MRSA can be easily treated by health care practitioners using local skin care and commonly available non-penicillin-family antibiotics. Rarely, CA-MRSA can cause serious skin and soft tissue (deeper) infections. Staph infections typically start as small red bumps or pus-filled bumps, which can rapidly turn into deep, painful sores. If you see a red bump or pus-filled bump on the skin that is worsening or showing any signs of infection (ie, the area becomes increasingly painful, red, or swollen), see your doctor right away. Many people believe incorrectly that these bumps are the result of a spider bite when they arrive at the doctor's office. Your doctor may need to test (culture) infected skin for MRSA before starting antibiotics. If you have a skin problem that resembles a CA-MRSA infection or a culture that is positive for MRSA, your doctor may need to provide local skin care and prescribe oral antibiotics. To prevent spread of infection to others, infected wounds, hands, and other exposed body areas should be kept clean and wounds should be covered during therapy.
