Mysterious bacteria 'superbug' spreads across country
In a matter of days after the middle-aged patient arrived at University of Virginia Medical Center, the stubborn bacteria in his blood had fought off even what doctors consider â€śdrugs of last resort.â€ť
â€śIt was very alarming; it was the first time weâ€™d seen that kind of resistance,â€ť says Amy Mathers, one of the hospitalâ€™s infectious disease specialists. â€śWe didnâ€™t know what to offer the patient.â€ť
The man died three months later, but the bacteria wasnâ€™t done. In the months that followed, it struck again and again in the same hospital, in various forms, as doctors raced to decipher the secret to its spread.
The superbug that hit UVA four years ago -- and remains a threat -- belongs to a once-obscure family of drug-resistant bacteria that has stalked U.S. hospitals and nursing homes for over a decade. Now, itâ€™s attacking in hundreds of those institutions, a USA TODAY examination shows, and itâ€™s a fight the medical community is not positioned to win.
The bacteria, known as Carbapenem-Resistant Enterobacteriaceae, or CRE, are named for their ability to fight off carbapenem antibiotics -- the last line of defense in the medical communityâ€™s toolbox. And so far, theyâ€™ve emerged almost exclusively in health care facilities, picking off the weakest of patients.
USA TODAYâ€™s research shows there have been thousands of CRE cases throughout the country in recent years -- they show up as everything from pneumonia to intestinal and urinary tract infections. Yet even larger outbreaks like the UVA episode, in which seven patients died, have received little or no national attention until now.
The bacteriaâ€™s ability to defeat even the most potent antibiotics has conjured fears of illnesses that canâ€™t be stopped. Death rates among patients with CRE infections can be about 40 percent, far worse than other, better-known health care infections such as MRSA or C-Diff, which have plagued hospitals and nursing homes for decades. And there are growing concerns that CRE could make its way beyond health facilities and into the general community.

40 percent of people infected die. That means that 60 percent live. Just makes you aware of how clever the human body is. Under normal evolutionary selection if allowed to apply this immunity may be passed on to the next generation and this bacteria will no longer be a problem.
