MRSA Staph...are we in danger?
I was watching tv yesterday and heard about this and I was amazed at how many people do not know about this!!
Alternative Names
Methicillin-resistant Staphylococcus aureus; Community-acquired MRSA (CA-MRSA); Hospital-acquired MRSA (HA-MRSA)
Definition:
Methicillin-resistant Staphylococcus aureus (MRSA) is an infection caused by a strain of Staphylococcus aureus (S. aureus) bacteria that is highly resistant to antibiotics.
Causes:
S. aureus (“staph”) is a common bacteria that normally lives on the skin and sometimes in the nasal passages. MRSA refers to S. aureus strains that do not respond to the antibiotics normally used to cure staph infections.
The bacteria can cause infection when it enters the body through a cut, sore, catheter, or breathing tube. The infection can be minor and local (for example, a pimple), or more serious (involving the heart or bone).
Serious staph infections are more common in people with weak immune systems, usually patients in hospitals and long-term care facilities and those receiving kidney dialysis.
MRSA infections are grouped into two types:
Healthcare-associated MRSA (HA-MRSA) infections occur in people who are or have recently been in the hospital. Those who have been hospitalized or had surgery within the past year are at an increased risk. MRSA bacteria are responsible for a large percentage of hospital-acquired staph infections.
Community-associated MRSA (CA-MRSA) infections are ones that occur in otherwise healthy people who have not recently been in the hospital. The infections have occurred among athletes who share equipment or personal items (such as towels or razors) and children in daycare facilities. Members of the military and those who receive tattoos are also at risk. The number of CA-MRSA cases is increasing.
Symptoms:
Staph skin infections normally cause a red, swollen, and painful area on the skin. Other symptoms may include:
Skin abscess
Drainage of pus or other fluids from the site
Fever
Warmth around the infected area
Symptoms of a more serious staph infection may include:
Rash
Shortness of breath
Fever
Chills
Chest pain
Fatigue
Muscle aches
Malaise (general feeling of illness)
Headache
Exams and Tests:
Depending on the extent and severity of your symptoms, your doctor may recommend the following tests to detect and confirm the bacteria causing the infection:
Blood culture
Culture of the drainage (fluid) from the infection
Skin culture from the infected site
Sputum culture
Urine culture
Treatment:
Draining the skin sore is often the only treatment needed for a local skin MRSA infection. This can be done at the doctor's offcie.
More serious MRSA infections, especially HA-MRSA infections, are becoming increasingly difficult to treat. Antibiotics that may still work include vancomycin (Vancocin, Vancoled), trimethoprim-sulfamethoxazole (Bactrim, Bactrim DS, Septra, Septra DS), linezolid (Zyvox), tetracycline (doxycycline), or clindamycin.
It is important to finish all doses of antibiotics you have been given, even if you feel better before the final dose. Unfinished doses can lead to development of further drug resistance in the bacteria.
Other treatments may be needed for infections that are more serious. The person will be admitted to a hospital. Treatment may involve:
Fluids and medications through a vein
Oxygen
Kidney dialysis (if kidney failure occurs)

Outlook (Prognosis):
How well a person does depends on the severity of the infection and their overall health. MRSA-related pneumonia and blood poisoning are associated with high death rates.
Possible Complications:
Serious staph infections may lead to:
Cellulitis
Endocarditis
Toxic shock syndrome
Pneumonia
Blood poisoning
Organ failure and death may result from untreated MRSA infections.
When to Contact a Medical Professional:
Call your healthcare provider if a wound seems to get worse rather than heal, or if you have any other symptoms of staph infection.
Prevention:
Careful attention to personal hygiene is key to avoiding MRSA infections.
Wash your hands frequently, especially if visiting someone in a hospital or long-term care facility.
Make sure all doctors, nurses, and other healthcare providers wash their hands before examining you.
Do not share personal items such as towels or razors with another person -- MRSA can be transmitted through contaminated items.
Cover all wounds with a clean bandage, and avoid contact with other people’s soiled bandages.
If you share sporting equipment, clean it first with antiseptic solution.
Avoid common whirlpools or saunas if another participant has an open lesion.
Ensure that communal bathing facilities are clean.
