Print Overview Methicillin-resistant Staphylococcus aureus MRSA infection is caused by a type of staph bacteria that's become resistant to many of the antibiotics used to treat ordinary staph infections. Most MRSA infections occur in people who've been in hospitals or other health care settings, such as nursing homes and dialysis centers.
HA-MRSA infections typically are associated with invasive procedures or devices, such as surgeries, intravenous tubing or artificial joints. Another type of MRSA infection has occurred in the wider community — among healthy people.
It's spread by skin-to-skin contact. At-risk populations include groups such as high school wrestlers, child care workers and people who live in crowded conditions. Symptoms Staph infection Staph infection Methicillin-resistant Staphylococcus aureus MRSA infections start out as small red bumps that can quickly turn into deep, painful abscesses.
Staph skin infections, including MRSA, generally start as swollen, painful red bumps that might resemble pimples or spider bites. The affected area might be: Warm to the touch Full of pus or other drainage Accompanied by a fever These can quickly turn into deep, painful abscesses that require surgical draining.
Sometimes the bacteria remain confined to the skin. But they can also burrow deep into the body, causing potentially life-threatening infections in bones, joints, surgical wounds, the bloodstream, heart valves and lungs.
When to see a doctor Keep an eye on minor skin problems — pimples, insect bites, cuts and scrapes — especially in children.

If wounds appear infected or are accompanied by a fever, see your doctor. Request an Appointment at Mayo Clinic Causes Different varieties of Staphylococcus aureus bacteria, commonly called "staph," exist. Staph bacteria are normally found on the skin or in the nose of about one-third of the population.
The bacteria are generally harmless unless they enter the body through a cut or other wound, and even then they usually cause only minor skin problems in healthy people. According to the Centers for Disease Control and Prevention, around 2 percent of the population chronically carries the type of staph bacteria known as MRSA.
Antibiotic resistance MRSA is the result of decades of often unnecessary antibiotic use. For years, antibiotics have been prescribed for colds, flu and other viral infections that don't respond to these drugs.
Even when antibiotics are used appropriately, they contribute to the rise of drug-resistant bacteria because they don't destroy every germ they target. Bacteria live on an evolutionary fast track, so germs that survive treatment with one antibiotic soon learn to resist others.
Risk factors Because hospital and community strains of MRSA generally occur in different settings, the risk factors for the two strains differ.
MRSA remains a concern in hospitals, where it can attack those most vulnerable — older adults and people with weakened immune systems. Having an invasive medical device. Medical tubing — such as intravenous lines or urinary catheters — can provide a pathway for MRSA to travel into your body.
Residing in a long-term care facility. MRSA is prevalent in nursing homes. Carriers of MRSA have the ability to spread it, even if they're not sick themselves. MRSA can spread easily through cuts and abrasions and skin-to-skin contact. Living in crowded or unsanitary conditions.
Outbreaks of MRSA have occurred in military training camps, child care centers and jails. Men having sex with men. Homosexual men have a higher risk of developing MRSA infections.
People who inject drugs are an estimated Complications MRSA infections can resist the effects of many common antibiotics, so they are more difficult to treat. This can allow the infections to spread and sometimes become life-threatening.
MRSA infections may affect your:Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) skin infections are an increasingly common reason to seek medical care in clinics, urgent care centers, and emergency departments and appear to have driven up rates of visits to practitioners for skin infections (4, 9).
Non-pharm prevention alternative for MRSA skin infections Longtime reader and botanical-medicine expert Robyn spotted this new story and study this morning and . This paper will shed light on the nature of the disease, its etiology, its agents and the current ways of treatment and prevention.
2 History, Occurrence and Etiology In its most simple sense, MRSA is a skin infection, whose early symptoms are an infected area on the . Introduction.
From its emergence in , until the late s, methicillin-resistant Staphylococcus aureus (MRSA) was largely a nosocomial pathogen, affecting patients undergoing surgery or dialysis, receiving prolonged courses of antibiotics, residing in long-term care facilities, or requiring indwelling catheters or percutaneous medical devices.
Diagnosis and Treatment of Staphylococcus aureus. S. aureus is part of the normal human flora (bacteria that normally reside in or on humans) and does not usually cause infection.
When bacteria are living on or in the human body, but are not causing infection, it is called “colonization.”. Methicillin-resistant Staphylococcus aureus (MRSA) infections are a problem in the United States1 and elsewhere.
Because this was not a research project, The MRSA Prevention Initiative may.
