...alarmed by the new killer bug. "We're out here waving our arms, trying to get everyone's attention," says Dr. Robert Daum, director of the University of Chicago's pediatric infectious-disease program, who was one of the first to call attention to the rapid spread of MRSA, back in 1998. "People talk about bird flu, but this is here...
...MRSA strains turning up in the community at large are related to but different from the ones found in medical institutions. The hospital variety usually requires intervention with powerful intravenous antibiotics and is pretty hard to catch. By contrast, the new strains of MRSA respond to a broader range of antibiotics but spread much more easily among otherwise healthy folks. The bugs can be picked up on playgrounds, in gyms and in meeting rooms, carried on anything from a shared towel to a poorly laundered necktie...
...difficulties in tracking MRSA is that doctors rarely check for it. The standard test usually takes a couple of days, and hardly any doctors do it anymore because everyone assumes that most skin infections respond to the usual antibiotics. "HMO's aren't going to be paying for you to do a culture on what they consider to be a [common] skin lesion," Bancroft says...
...mucus linings of the nose. Most of those bacteria don't cause illness, and in fact their presence is a good thing, since they can crowd out more dangerous pathogens. But every once in a while, the good guys take a beating, and one of the bad guys, like MRSA, takes hold, colonizing the skin...
...happens, it doesn't necessarily signal an emergency. The skin, after all, is an effective barrier against many kinds of threats. But anytime you get a break in that barrier--even a tiny cut--there's a chance some bacteria will get inside and infect the wound. What makes MRSA germs particularly dangerous is that they excrete a potent toxin that attacks the skin, causing an abscess that's often mistaken for a spider bite. Normally, the body can wall that area off. But if the infection spreads, treatment with antibiotics may be called...
