Methicillin-resistant Staph Aureus FAQ (adapted from CDC)
What is MRSA?
MRSA stands for Methicillin-resistant Staphylococcus aureus, which is a strain of Staphylococcus aureus that has acquired resistance to several antibiotics.
Staph aureus can be part of the normal bacterial flora and typically colonizes on the skin and in the nose.
MRSA most commonly causes skin infection, which presents as swelling, redness, warmth, and pain in the affected area.
If left untreated, MRSA can infect the bloodstream causing sepsis leading to more severe complications.
Although MRSA is not an immediately life-threatening condition, anyone who suspects MRSA infection should seek treatment urgently to prevent further complications from the infection.
MRSA can be spread in the community through contact with contaminated objects, skin injuries, or contact with infected individuals.
What are the risk factors associated with MRSA?
Prolonged stay at a hospital
Recent surgery
Implanted medical devices
Skin injury
Previous MRSA infection
Family history of MRSA infection
What are the recommended guidelines for preventing MRSA?
Following and maintaining contact precautions for known MRSA infections are the most effective means of preventing transmission.
What steps can patients and team members take to prevent MRSA?
Maintaining proper hand and body hygiene is the most important means of preventing MRSA infection.
All individuals interacting with the patient should use personal protective equipment (PPE), which includes donning a gown and gloves.
How do I diagnose the condition? What other things are in the differential diagnosis?
Common signs and symptoms of MRSA infection include:
Skin swelling
Warmth, redness, pain in the affected area
Fever
Leukocytosis
For the differential diagnosis of a skin infection, other bacteria can present similarly. These include primarily other Staphylococcus and Streptococcus species.
How do I treat/manage the clinical condition?
Treatment of MRSA infections often requires inpatient admission with long-term IV antibiotic therapy such as Vancomycin or Daptomycin.
Avoid direct skin-to-skin contact with others is essential for preventing the spread of MRSA.
What complications are associated with MRSA?
The most critical and life-threatening complications of MRSA are bacteremia and sepsis.
