How is an infection diagnosed?
If your doctor thinks that you are infected with
MRSA, he or she will send a sample of your infected wound, blood, or urine to a
lab. The lab will grow the bacteria and then test to see which kinds of
antibiotics kill the bacteria. This test may take several days.
You may also be tested if your doctor suspects that you are a MRSA
carrier. A MRSA carrier is a person who has the bacteria on his or her skin but
who is not sick. This is done by taking a swab from the inside of the

your skin or inside your nose and be asked to wash your skin daily with an
antibiotic soap called chlorhexidine (Hibiclens) to reduce MRSA bacteria on
If you have a MRSA infection and need to be in a
hospital, you may be isolated in a private room to reduce the chances of
spreading the bacteria to others. When your doctors and nurses are caring for
you, they may use extra precautions such as wearing gloves and gowns. If you
have a MRSA pneumonia, they may also wear masks.
Most cases of
community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) begin as mild skin infections such as pimples or boils.
Your doctor may be able to treat these infections without antibiotics by using
a minor surgical procedure that opens and drains the sores.
