More than 90,000 Americans get potentially deadly infections each year from a drug-resistant staph ''superbug,'' the government reported Tuesday in its first overall estimate of invasive disease caused by the germ.

Deaths tied to these infections may exceed those caused by AIDS, said one public health expert commenting on the new study. The report shows just how far one form of the staph germ has spread beyond its traditional hospital setting.

The overall incidence rate was about 32 invasive infections per 100,000 people. That's an ''astounding'' figure, said an editorial in Wednesday's Journal of the American Medical Association, which published the study.

Most drug-resistant staph cases are mild skin infections. But this study focused on invasive infections -- those that enter the bloodstream or destroy flesh and can turn deadly.

Researchers found that only about one quarter involved hospitalized patients. However, more than half were in the health care system -- people who had recently had surgery or were on kidney dialysis, for example. Open wounds and exposure to medical equipment are major ways the bug spreads.

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

The new study offers the broadest look yet at the pervasiveness of the most severe infections caused by the bug, called methicillin-resistant Staphylococcus aureus, or MRSA. These bacteria can be carried by healthy people and live on their skin or in their noses.

An invasive 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 muscles around his heart.

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% involved so-called flesh-eating disease, according to the study led by researchers at the federal Centers for Disease Control and Prevention.

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 other better-known causes of death including AIDS -- which killed an estimated 17,011 Americans in 2005 -- said Elizabeth Bancroft of the Los Angeles County Health Department, the editorial author.

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

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 their overuse could cause the germ to become resistant to those too.

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

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

The regions studied were the state of Connecticut, the city of Baltimore, and the metropolitan areas of Atlanta; Denver; Nashville; Portland, Ore.; Rochester, N.Y.; St. Paul, Minn. [all communities within Ramsey County]; and metropolitan San Francisco. (Lindsey Tanner, AP)
