MRSA Infections in Hospitals and the Community Continue to Rise

MRSA is a staph becteria which has been in the news in recent years as serious problems have been reported in hospitals and other health care facilities. Staph bacteria, even those that aren’t resistant to antibiotics, have long caused serious infections.
In the 1960s, the first reports surfaced of staph infections that had stopped responding to the antibiotic methicillin. Over the decades, those strains have spread, and the germs have developed resistance to other drugs, largely in hospitals where they infect patients weakened by disease or made vulnerable through surgical wounds and catheters.
MRSA still poses the greatest threat in hospitals, where strains are usually genetically different and, because of antibiotic use, more difficult to kill than those circulating out in the community. About 85 percent of life-threatening, invasive MRSA infections involve people who have been hospitalized, lived in a nursing home or been treated in some other health care facility.
During the 1980s, doctors began finding cases of MRSA in people who hadn’t spent time in health care settings. Unlike the strains found in hospitals, MRSA in the community tended to cause skin infections — pus-filled pimples and boils.
Community MRSA still responds to a wider range of antibiotics, and it is unusual for community infections to become life-threatening. However, a study reported last year that more life-threatening community infections occur than previously thought.
The study, estimated MRSA infections in health care facilities and the community killed nearly 19,000 Americans in 2005. Another 94,000 had life-threatening infections.
However, the study found that 85% of life-threatening MRSA infections involved people who have been infected while hospitalized or living in a nursing home. Only about 15 percent happened in the community.
People 65 and older are most likely to suffer invasive MRSA infections of all types, the study found. Black people had invasive MRSA at nearly twice the rate of whites.
The important thing to remember is that those who seek help from a doctor usually are successfully treated. One should not ignore these problems.
