Methicillin Resistant Staphylococcus aureus (MRSA) is nothing new. It has been around since the 1960s, but it’s getting a lot of media attention these days because it is becoming more widespread. Should you worry? No, but you should be aware and take steps to minimize your risks. Read on to learn what people with cystic fibrosis need to know about MRSA.
What Is MRSA?
MRSA is a strain of the Staphyloccus aureus bacteria that is resistant to many common antibiotics. Originally, MRSA infections were spread among people in the hospital or other healthcare facilities. This is no longer the case. While the majority of MRSA infections do still occur in hospitalized patients, the bacteria has spread beyond hospital walls to infect people in the community.
In the community setting, MRSA usually causes skin infections. In healthcare facilities, MRSA tends to cause infections in:
- Urinary tract
What Happens to People Who Are Infected With MRSA?
Staphylococcus aureus, which is sometimes referred to merely as “staph", likes to live on our skin and in our noses -- and often does so without making us sick. In fact, about 30% of us are colonized with some strain of staph bacteria. 1% of the time that strain is MRSA.
MRSA infections occur when, instead of just hitching a ride on our bodies, the MRSA bacteria invade our bodies and cause illness. Without treatment, MRSA infections can cause severe tissue damage and in some cases, even death. Fortunately, these scenarios are pretty rare because most MRSA infections are treatable. Even though MRSA is resistant to some antibiotics, it is not resistant to all of them.
Are People With Cystic Fibrosis at Risk for MRSA Infections?
People with cystic fibrosis (CF) are no more or less likely to get a community acquired MRSA infection than anybody else, but they are at an increased risk for hospital acquired MRSA infections because:
- Frequent hospitalizations increase exposure to MRSA
- Thick mucus trapped in the airways increases the risk of MRSA lung infections
- PICC lines and other types of long-term IV access increase the risk of MRSA wound or blood infections
How Is MRSA Spread?
MRSA is spread through direct or indirect contact. One of the things that makes MRSA so contagious is that it can live on inanimate objects for weeks or even months. You can become infected with MRSA by touching:
- Another person who has a MRSA infection
- An object that has been contaminated with MRSA
- A caregiver or other person who has touched someone or something that is contaminated with MRSA
How Can I Reduce My Risk of a MRSA Infection?
In the community, you can reduce the risk of MRSA infection by:
- Practicing good hand washing
- Keeping cuts and other wounds covered
- Not sharing equipment, razors, towels, or other personal items -- even among siblings or family members
In the hospital, your caregivers should be taking steps to prevent the spread of MRSA including:
- Washing their hands between contact with patients
- Changing PICC line dressings at least once a week using sterile technique
- Avoiding the use of shared equipment whenever possible
- Ensuring that reusable equipment is not used for the care of another patient until it has been appropriately cleaned and reprocessed and that single-use items are properly discarded
- Placing people with MRSA infections in private rooms using contact precautions
