Oct. 4, 2007 -- Rocky Mountain spotted fever is becoming more common -- and not just in the Rocky Mountains.
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.
