CHICAGO - It now appears a dangerous type of staph infection is probably killing more Americans each year than AIDS.

It's resistant to standard antibiotics, and the government reports in its first broad look at invasive disease caused by this "superbug" that more than 90,000 Americans are sickened by it annually.

The drug-resistant germ goes by the nickname MRSA, short for methicillin- resistant Staphylococcus aureus.

"The rate of invasive MRSA was an astounding 31.8 per 100,000," according to an editorial published with the report in today's Journal of the American Medical Association.

The study offers the broadest look yet at the pervasiveness of the most severe MRSA infections - those that invade the bloodstream or destroy flesh. Healthy people can carry these bacteria, living on their skin or in their noses. But the bacteria can be deadly when they spread inside the body.

This form of the disease is being blamed for the death Monday of a 17-year-old Virginia high school senior. Doctors said the germ had spread to his kidneys, liver, lungs and the muscles around his heart.

In recent years, MRSA has become more common in hospitals and it has been spreading through prisons, gyms and locker rooms, and in poor urban neighborhoods.

Researchers found that only about one-quarter of invasive cases involved patients in hospitals. However, more than half were related to health care, occurring in people who were on kidney

 

dialysis or recently had surgery, for example. Open wounds and exposure to contaminated medical equipment are major ways the bug spreads. There were 988 reported deaths among infected people in the study, for a rate of 6.3 per 100,000. That would translate to 18,650 deaths annually, although the researchers don't know if MRSA was the cause in all cases.

If these deaths all were related to staph infections, the total would exceed the number killed in the U.S. by better-known causes including AIDS, which killed an estimated 17,011 Americans in 2005, said Dr. Elizabeth Bancroft of the Los Angeles County Health Department, who wrote the editorial published with the study.

The researchers' estimates are extrapolated from 2005 surveillance data from nine mostly urban regions considered representative of the country. There were 5,287 invasive infections reported that year in people living in those regions, which would translate to an estimated 94,360 cases nationally, the researchers said.

Most cases were life-threatening bloodstream infections. However, about 10 percent involved what some call "flesh-eating" disease, according to the study led by researchers at the federal Centers for Disease Control and Prevention.

The results underscore the need for better prevention measures, such as curbing the overuse of antibiotics and improving hand-washing and other hygiene procedures, especially among hospital workers, said the CDC's Dr. Scott Fridkin, a study co-author.

Some hospitals have drastically cut infections by first isolating new patients until they are screened for MRSA.

The bacteria don't respond to penicillin-related antibiotics once commonly used to treat them, partly because of overuse. They can be treated with other drugs but health officials worry that overuse could cause the bacteria to become resistant to those, too.

A survey earlier this year suggested that MRSA infections, including noninvasive mild forms, affect 46 of every 1,000 U.S. hospital and nursing home patients - or as many as 5 percent. These patients are vulnerable because of open wounds and invasive medical equipment that can help the germ spread.

Dr. Buddy Creech, an infectious-disease specialist at Vanderbilt University, said the JAMA study emphasizes the broad scope of the drug-resistant staph infections and highlights the need for a vaccine, which he called "the holy grail of staphylococcal research."

The study involved data from July 2004 through December 2005, during which 8,897 cases of invasive MRSA disease were reported. The incidence rate and death rate were calculated based only on the 2005 data, which involved 5,287 cases.

The regions studied were: the Atlanta metropolitan area; the Baltimore area; the state of Connecticut; Davidson County, Tenn.; the Denver metropolitan area; Monroe County, N.Y.; the Portland, Ore., metropolitan area; Ramsey County, Minn.; and the San Francisco metropolitan area.

Well then kick the snot out of the superbug with "The Beck Protocol". I don't think there's a bug out there that can withstand that...not even the mighty SUPERBUG! LOL But seriously, they're simple and cheap to build and they DO work.
