Rocky Mountain spotted fever (RMSF) is a potentially fatal disease that occurs most often in Oklahoma and the South Atlantic states, although it has been found in most states. It is caused by an infection with the bacteria Rickettsia rickettsii.

The rash associated with Rocky Mountain spotted fever usually starts around 4 days into the illness. It looks like small, red, flat spots starting most often on the ankles and wrists, and then moving to the palms, soles, and trunk. As the rash progresses, it becomes bumpier. Approximately 10% of those infected never get a rash.
