What is Rocky Mountain spotted fever? Rocky Mountain spotted fever (RMSF) is a tick-borne disease caused by a rickettsia (a microbe that differs somewhat from bacteria and virus). Fewer than 50 cases are reported annually in New York State.
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.
