Rocky Mountain Spotted Fever Rising

Rocky
Mountain sp otted f ever is becoming more common --
and not just in the Rocky Mountains.

Rocky Mountain spotted fever is a potentially deadly disease caused by
bacteria called Rickettsia rickettsii, which are carried by certain
ticks.

Reported U.S. cases of Rocky Mountain spotted fever more than tripled
between 2001 and 2005, according to the CDC's David Swerdlow, MD, and
colleagues.

They presented their findings today in San Diego at the 45th annual meeting
of the Infectious Diseases Society of America (IDSA).

In 2001, there were two reported cases of Rocky Mountain spotted fever per
million people in the U.S. That figure rose to 7.1 cases per million people in
2005.

Suburbs saw a bigger jump in Rocky Mountain spotted fever cases than rural
areas.

"This disease is becoming more common in cities and suburbs, likely
because people are going to rural areas and coming home to the cities, and
possibly also because suburbia is encroaching on rural, tick-infested
areas," Swerdlow says in an IDSA news release.

Preventing Rocky Mountain Spotted Fever

The CDC's web site provides these five tips to limit exposure to ticks:

• Wear light-colored clothing to make it easier to see (and remove)
  ticks.


• Tuck your pants legs into your socks so ticks can't crawl up the inside of
  your pants legs.


• Use repellents to discourage ticks from latching on to skin, clothes, or
  boots (follow product directions).


• Check your whole body for ticks after visiting potentially tick-infested
  areas.


• Check kids' hair and scalp
  after they've been in potentially tick-infested areas.
