Abstract. Background and objectives: Rocky Mountain spotted fever (RMSF) is a rapidly progressive and potentially fatal tickborne disease caused by Rickettsia rickettsii. Despite current recommendations and information on the severity of RMSF, studies show that delayed recognition and treatment continues to occur.
Rocky Mountain spotted fever (or "black measles" because of its characteristic rash) was recognized in the early 1800s, and in the last 10 years of the 1800s (1890–1900) it became very common, especially in the Bitterroot Valley of Montana. The disease was originally noted to be concentrated on the west-side of the Bitterroot river. [31]

It is most common in the south Atlantic and south central regions of the U.S. however cases are reported from Canada, Central and South America, as well as almost all 50 states.
