Methicillin Resistant Staphylococcus Aureus (MRSA)

This information explains methicillin resistant Staphylococcus aureus (MRSA), including how it spreads and how infections are treated.

What is methicillin resistant Staphylococcus aureus?

Staphylococcus (staph) is a type of bacteria that naturally exist in the environment, including on people’s skin. Methicillin resistant Staphylococcus aureus (MRSA) is a type of staph bacteria that is resistant to certain antibiotics. This means that some treatments will not work or may be less effective.

MRSA can cause a variety of illness, including:

  • Urinary tract infections (UTIs)
  • Pneumonia
  • Blood infections
  • Wound or skin infections

What is the difference between being colonized and being infected with MRSA?

A person can be either colonized or infected with MRSA. If a person is colonized, it means that the bacteria is present on their skin or in their body, but they have no symptoms. If a person is infected, it means that the bacteria is present on their skin or in their body and it’s causing symptoms.

How does MRSA spread?

Most MRSA infections are spread by direct contact with an infected person’s bodily fluids, such as blood, drainage from a wound, urine, bowel movements, or sputum (phlegm). It can also be spread by touching equipment or surfaces that have come in contact with the bacteria. Casual contact, such as touching or hugging, doesn’t spread MRSA.

What isolation precautions are taken in the hospital if I have a MRSA infection?

Isolation precautions are steps we take to stop infections from spreading from person to person. If you’re diagnosed with or exposed to a MRSA infection while you’re in the hospital:

  • You will be placed in a private room.
  • A sign will be posted on your door telling all staff and visitors to clean their hands with soap and water or an alcohol-based hand sanitizer before going into and after leaving your room.
  • All staff and visitors who enter your room must wear a yellow gown and gloves. These are available outside of your room and can be disposed of inside your room.
  • If you leave your room for tests, you must wear a yellow gown and gloves or be covered with a clean sheet.
  • If you leave your room to walk around the unit, you must wear a yellow gown and gloves.
  • You will not be able to go to the following areas of the hospital:
    • Pantry on your unit
    • Recreation center on M15
    • Pediatric recreation areas on M9
    • Cafeteria
    • Main lobby
    • Any other public area of the hospital
  • You can have art or massage therapy in your room while following isolation precautions.

Your doctor will let you know when you can stop following these precautions. This will be after you’re treated and no longer have symptoms.
