California state law requires hospitals to test some patients for a germ called methicillin-resistant Staphylococcus aureus, or MRSA. If you're admitted to the hospital at UCSF Medical Center for surgery and you're considered susceptible for MRSA infection, you will be tested for this germ.
Staphylococcus aureus, pronounced staff-ill-oh-KOK-us AW-ree-us, or "staph" are a common bacteria. MRSA is a type of staph that isn't killed by penicillin or similar antibiotics, the drugs most commonly used to treat staph infections. It is resistant to many antibiotics, making it more difficult to treat.
About one out of every three people has staph on his or her skin or in the nose without it causing any problem, and about one out of every 100 people carry MRSA without getting sick. However, in some cases staph or MRSA can cause an infection. An infection may look like any of the following:
Infections caused by MRSA don't look any different from infections caused by ordinary staph.
If your MRSA test is positive, you are considered "colonized" with MRSA. Being colonized simply means that at the moment your nose was swabbed, MRSA was present. If the test is negative, it means you aren't colonized with MRSA.
In most cases, being colonized with MRSA doesn't make you sick and no treatment is necessary. If you have an infection, your doctor will treat it. Treatments may include draining the sores or taking antibiotics.
Carry on with your daily life as usual and follow the simple suggestions listed below to help prevent MRSA from causing problems.
Staph and MRSA can spread to others through skin-to-skin contact and by touching surfaces contaminated with the bacteria, such as towels or used bandages. It's generally not spread through the air.
Routine cleaning of your hands and environment is the best way to prevent your infection from spreading to others.
If you're given antibiotics, take all of them, even if your symptoms improve. If your infection doesn't improve within several days, call your doctor.
Your doctor or nurse can answer any other questions you have about MRSA.
