Drug-Resistant Staph Infection Spreads to Gyms, Day Care
By Stefan Lovgren, April 25,

A potentially lethal
strain of staph infection was once a worry mainly in hospitals. But
MRSA (methicillin-resistant Staphylococcus aureus) is becoming
increasingly common in gyms, day care centers, prisons, and other
venues where people are in close contact and hygiene is often lacking.
MRSA is a type of
Staphylococcus bacterium that is resistant to penicillin and some
other antibiotics. The bacteria invade the body via cuts in the skin,
causing infection that can be debilitating if not treated early and
with the appropriate antibiotics. In rare instances MRSA can be
lethal.
Athletes, including
gym-goers, may be at risk. In 2003 five members of the St. Louis Rams
football team were infected with MRSA. The infections of the players
were associated with “turf burns.” The bacteria were likely spread
among players through shared towels, whirlpool baths, and
weightlifting equipment.
MRSA is not, however, a
disease that affects just athletes. “This disease is spread by close
skin-to-skin contact, crowding, sharing contaminated items,” Nicole
Coffin, a spokesperson at the Centers for Disease Control and
Prevention (CDC) in Atlanta, Georgia, said. “Cleanliness is a big
issue. “At this point, everybody in the community can be at risk for
MRSA,” she said.
Changing Epidemiology
Staph bacteria are
commonly carried by people on the skin or in their noses. Staph is the
most common cause of skin and soft-tissue infection.
Some staph strains are
resistant to conventional antibiotics, such as methicillin (a
synthetic form of penicillin), and are known as MRSA.
“We think about one
percent of the U.S. population, or about two million people, carry
this drug-resistant form of staph,” Coffin said.
MRSA has been seen in
hospitals for about 30 years. There, it usually occurs among people
with weakened immune systems, such as elderly patients with underlying
illnesses, and patients who have had surgery.
The hospital-based
infection may start out as redness around an intravenous line entry or
a surgical wound, but it can spread to the lungs, causing pneumonia,
or to the blood, causing breathing difficulties, fever, and malaise,
possibly resulting in a life-threatening disease.
In 1998 health officials
began seeing a new MRSA strain in people with no ties to health care
settings. One major outbreak occurred in a prison.
Unlike hospital-based
MRSA, community-based strain has been affecting healthy people.
“The fact that we’re now
seeing more infections among people without risk factors who are
healthy represents a significant change in the epidemiology of this
type of infection,” Sara Zimmerman, an epidemiology specialist at the
Mecklenburg County Health Department in Charlotte, North Carolina,
said.
Community-based infections
are usually superficial and easier to treat than those in hospitals,
and often resemble a pimple or a spider bite that can be red, swollen,
and filled with pus.
If not treated
appropriately, the infections can lead to serious infections of the
blood or bone.
Health officials don’t
know how many people fall sick with the community-based MRSA. But the
CDC’s Coffin says about 25 percent of cases may result in
hospitalization.
Gyms, Prisons, and Day Care Centers
Experts say the emergence
of new MRSA shows the problem associated with antibiotic use.
“Due to the heavy use of
antibiotics in Western medicine, these [staph] organisms have had the
opportunity to develop mechanisms for resistance,” Zimmerman said.
“Unfortunately these organisms continue to exhaust our resources for
combating these types of infections, making treatment options for
clinicians very limited.
“Because this infection is
so common, the focus has shifted to prevention and control versus
eradication,” she added.
MRSA is spread in two
ways: by physical contact with an infected person or by touching
inanimate objects like towels, linens, razors, or weightlifting
equipment contaminated with bacteria.
It’s not a disease that
primarily affects athletes. But sports involving close contact, such
as American football or wrestling, put athletes at higher risk for
this infection.
Settings with close
contact and lack of proper hygiene behaviors are particularly at risk,
and prisons and day care centers may be highly vulnerable.
“Humans are reservoirs for
staph,” the CDC’s Coffin said. “The most important thing for people to
do is to keep an eye out for skin infections. Cover all wounds. If you
have a skin infection, you should go to a doctor and have it looked
at.
“Make sure your hands are
clean, and don’t share any personal items like towels and razors,” she
added.
After the outbreak among
the St. Louis Rams players, officials there beefed up their defense
against the disease by installing wall-mounted soap dispensers at the
team’s training facility and instructing players on how to care for
wounds and how to monitor skin infections.
