• Usually results from a scrape or cut in the skin which allows bacteria to enter, although no injury may be apparent.
  • Cellulitis can occur anywhere in the body, but most often occurs on the legs or arms.
  • redness, swelling, and pain at the site of infection.
  • S. aureus is most often spread to others by contaminated hands.

  • The skin and mucous membranes are usually an effective barrier against infection. However, if these barriers are breached (e.g., skin damage due to trauma or mucosal damage due to viral infection) S. aureus may gain access to underlying tissues or the bloodstream and cause infection.

  • Persons who are immunocompromised or who have invasive medical devices are particularly vulnerable to infection.

MRSA transmission:


  • Most skin infections resolve without treatment, however, some infections require incision and drainage or antibiotic treatment to cure the infection.

  • Skin infections that are left untreated can develop into more serious life-threatening infections such as infections of the bone or blood.

  • Some people experience repeated infections with S. aureus.

  • There is a possibility for longer lasting or more severe infections with Methicillin-resistant Staphylococcus aureus (MRSA) if the initial antibiotic prescribed is not capable of killing the bacteria.
