Staph Infection (Non-MRSA)
Staph Infection (Non-MRSA)
Staphylococcus aureus bacteria are
often called “staph.” They are common germs that can cause a variety of problems.
range from mild skin infections to severe infections of your skin, deep tissues, lungs,
bones, and blood. Most healthy adults normally carry staph on their nose and skin.
Typically, they do not cause disease. But if your skin is broken or opened, staph
enter your body and cause infection. Staph infections often get better on their own
easily treated with antibiotics. But it is becoming more common to see bacteria that
resistant to antibiotics, or hard to kill with them. This sheet tells you more about
infections and what you can do to prevent them.
How does staph spread?
Staph spreads through skin-to-skin
contact with an infected person. It also spreads through contact with contaminated
objects, such as shared towels, household items, or athletic equipment.
Who is at risk for a staph
Anyone can get a staph infection.
Certain risk factors make it more likely, including:
Living or having close
contact with someone who has staph
Having an open wound or
Playing contact sports or
sharing towels or athletic equipment
A current or recent stay in a
hospital or long-term care facility
A recent surgery or wound
Having a feeding tube or
catheter in your body
Receiving kidney dialysis
Having a weak immune system
or serious illness
Injecting illegal drugs
What conditions can be caused by a staph
Staph infections usually start in
your skin. They sometimes appear as small red bumps that look like pimples or spider
bites. These sores can turn into abscesses. These are pus-filled areas of infection.
Staph infections can also spread deeper into your body, causing 1 or more of these:
Infections in bones
(osteomyelitis), muscles, and other tissues
Infection in a wound from a
Infection in the bloodstream
Infection of the lining
of your heart and your heart valves (endocarditis)
Illness caused by the toxins
staph produces (toxic shock syndrome)
Staph skin infection causing
blisters and raw skin (scalded skin syndrome)
How is a staph infection
Your healthcare provider can often
diagnose staph infection based on how it looks. With a more serious infection, testing
may be done. Often, a sample of blood or urine is taken. A sample of fluid leaking
a wound, mucus from the lungs (sputum), or infected tissue can also be used. The sample
is sent to a lab and tested for staph.
How is a staph infection treated?
A minor skin infection is often
treated with warm soaks and basic wound care, including a bandage. If the infection
more serious, an antibiotic may be prescribed, either as a pill or an ointment. For
even more severe infection your provider may prescribe a more powerful antibiotic
intravenously. If you have a pocket of pus (abscess), your provider may drain it.
How can I prevent staph
To reduce the spread of staph
infections, keep cuts and scrapes clean and covered until they heal. Avoid contact
the wounds or bandages of others. Don’t share personal items such as towels, razors,
clothing, or athletic equipment. Keep your hands clean. Your best option is washing
hands with soap and water for at least 15 to 30 seconds. If that’s not possible,
your hands aren’t visibly dirty, use a hand gel that contains at least 60% alcohol.
Tips for good handwashing:
- Use water (either cold or warm is fine) and plenty of soap. Work
up a good lather.
- Clean your whole hand, under your nails, between your fingers,
and up your wrists.
- Wash for at least 15 to 30 seconds. Don’t just wipe. Scrub
- Rinse, letting the water run down your fingers, not up your
- Dry your hands well. Use a paper towel to turn off the faucet
and open the door.
Tips for using alcohol-based hand gels:
- Use enough gel to get your hands fully wet.
- Rub your hands together briskly. Clean the backs of your hands,
the palms, between your fingers, and up your wrists.
- Rub until the gel is gone and your hands are fully dry.
Taking antibiotics correctly
You may have heard of MRSA
(methicillin-resistant Staphylococcus aureus). This is a type of staph bacteria that
hard to kill (resistant) with many antibiotics that used to be effective against it.
This means the bacteria can’t be treated with some antibiotics (such as methicillin)
that work on other types of staph. But, other effective antibiotics are available.
Resistant bacteria can be picked up
from others, or can develop when antibiotics are not prescribed or taken correctly.
includes when they are taken longer than needed, not taken long enough, or taken when
they’re not needed. This is why your healthcare provider may not prescribe antibiotics
unless he or she is certain they are needed. It’s also why you must take antibiotic
medicine exactly as your healthcare provider tells you. This means not skipping doses,
and taking the medicine until it’s finished, even if you’re feeling better.
