Mrsa | 'Superbug' MRSA Infections Aren't Dropping In Children: CDC


MONDAY, Sept. 23 (HealthDay News) — Although rates of infection with methicillin-resistant staphylococcus aureus ( MRSA ) are declining among American adults, the rates among children remain largely unchanged, a new government study finds.

In addition, MRSA disproportionately affects infants less than 3 months old and black children, according to the report from the U.S. Centers for Disease Control and Prevention, published online Sept. 23 and in the October print issue of Pediatrics .

MRSA is considered a “superbug” because it’s resistant to nearly all treatments, including the powerful antibiotic methicillin. The most recent figures from the CDC, reported in the Sept. 16 issue of JAMA Internal Medicine , found that 30,000 fewer MRSA infections occurred in 2011 compared to 2005.


Fortunately, rates in children are much lower than what has been reported in adults, according to the latest study’s lead author, Dr. Martha Iwamoto, a medical epidemiologist with the CDC. However, the number of cases in children didn’t decline significantly from 2005 to 2010.

The one bright spot in the latest findings was in infants under 90 days old. “We found that the numbers of invasive MRSA infections among young infants are going down,” Iwamoto said.

However, the incidence of infections in babies younger than 3 months was still significantly higher than in other children.

Rates of infections in black children were more than four times higher than in children of other races.

“We are making some progress in reducing the number of invasive MRSA infections in young infants in hospitals. However, more needs to be done, especially for children developing invasive MRSA outside of hospitals,” she said.

MRSA can cause a variety of illnesses from skin infections to a life-threatening blood infection. These types of infections were initially prominent in hospital settings, but even as prevention measures have reduced the number of infections within hospitals, community-based infections have increased.

To better identify how this super bug is affecting infants and children, Iwamoto and her colleagues reviewed reports of MRSA infections across the United States from 2005 to 2010.

They found a total of 876 pediatrics cases, 39
