Reporting and Surveillance:
As of January 1, 2010, cases of RMSF are reported under a new category called Spotted Fever Rickettsiosis (including Rocky Mountain spotted fever). This change was made by the Council of State and Territorial Epidemiologists to better reflect the scope of cases being reported under the previous heading of RMSF, as many of those cases were not identified as being specifically caused by R. rickettsii.
