METHICILLIN-RESISTANT
STAPHYLOCOCCUS AUREUS
(MRSA)
What is MRSA?
Methicillin-resistant Staphylococcus
aureus (MRSA) is a type of Staphylococcus aureus (“staph”) bacteria.
“Staph” is a common type of bacteria that may be frequently found on healthy
persons’ skin and in their noses. It can also grow in sores or other
sites in the body, sometimes causing an infection. Penicillin is
an antibiotic that was once commonly used to treat staph infections.
Many staph bacteria are no
longer killed by penicillin and antibiotics related to penicillin.
These new or resistant forms of Staphylococcus aureus cause MRSA infections,
and they require special medications because some antibiotic medications
will not kill the bacteria. The illnesses they cause are the same
as those caused by other staph; the difference is in how they are treated.
What are the symptoms
of MRSA infection?
Frequently a MRSA infection
looks like a pimple, rash, boil, or an open wound. Sometimes people
think it is a spider bite. The skin infection caused by MRSA can have redness,
warmth, swelling, pus, and/or pain. If not treated properly, MRSA
skin infection may progress quickly from a soreness of the skin to an abscess
or other serious body infection. Many people carry staph bacteria
on their skin without any symptoms.
How is MRSA spread?
MRSA lives on skin and can
live on objects for 24 hours or more. Drainage or pus from skin lesions
can spread MRSA bacteria to other parts of a person’s body or to other
persons. MRSA can rub off the skin of an infected person onto the
skin of the other person during body contact. MRSA can also come
off the infected skin of a person onto a shared object or surface and get
onto the skin of the next person who uses it. Examples of shared
objects include razors, towels, clothing, and sporting equipment.
How long are people contagious?
Persons can spread MRSA
as long as they are carrying it.
Who gets MRSA?
Anyone can get MRSA.
Just like normal staph bacteria, MRSA normally does not cause disease unless
it enters an opening in the skin. Some people are at a greater risk
for carrying MRSA or becoming infected with this type of “staph.”
It occurs more frequently in people in hospitals and healthcare facilities.
However, it can also happen outside the hospital in people who either receive
multiple antibiotics or come in frequent contact with the germ. This
may occur when they have close contact with a person carrying the bacteria
or by touching objects “dirtied” or contaminated with MRSA (e.g., clothes,
towels, bedding, sporting equipment, benches in saunas or hot tubs, bandages).
Crowded living conditions (schools, jails) and poor hygiene can contribute
to the spread of MRSA infections.
What treatment is available
for people with MRSA?
Early treatment can help
prevent the infection from getting worse. If you have a bad abscess,
the doctor should drain the pus. If you are given medicine, be sure
to take all of your pills. Be sure to follow directions from your
doctor, even when you start to feel better.
Do infected people need
to be kept home from school, work or daycare?
No. Persons with MRSA
skin infections should keep the infected area covered with clean, dry pads.
They may need to avoid certain activities such as gym class to prevent
the covering from coming off.
How can I protect myself
and my family from getting MRSA?
-
Wash your hands a lot with soap
and warm water.
-
Keep cuts and scrapes clean
with soap and water.
-
Do not pick, touch, or scratch
your skin infections or touch someone else’s sores.
-
Avoid skin contact and sharing
personal items with anyone you think could have an MRSA skin infection.
-
Don’t insist on antibiotics
for colds or other viruses.
-
If prescribed antibiotics, take
all the pills, even if you feel better before they are all gone
