How to Contact the Rickettsial Zoonoses Branch at CDC
The general public and healthcare providers should first call 1-800-CDC-INFO (1-800-232-4636) for questions regarding RMSF and other rickettsial diseases. If a consultation with a CDC scientist specializing in rickettsial diseases is advised, your call will be appropriately forwarded.
As of January 1, 2010, cases of RMSF are reported under a new category called Spotted Fever Rickettsiosis (including Rocky Mountain spotted fever).
Case Report Forms
For confirmed and probable cases of RMSF that have been identified and reported through the National Notifiable Disease Surveillance System, states are also encouraged to submit additional information using CDC Case Report Forms (CRFs). These forms collect additional important information that routine electronic reporting does not, such as information on how the diagnosis was made, and whether the patient was hospitalized or died. If a different state-specific form is already used to collect this information, this information may be submitted to CDC in lieu of CRFs.

How to Submit Specimens to CDC for RMSF Testing
Private citizens may not directly submit specimens to CDC for testing. If you feel that diagnostic testing is necessary, consult your healthcare provider or state health department.
State Health Departments
Specimens may be submitted to CDC for testing for rickettsial diseases, including RMSF. To coordinate specimen submission, please call 404 639 1075 during business hours (8:00 - 4:30 ET).
U.S. Healthcare Providers
U.S. healthcare providers should not submit specimens for testing directly to CDC. CDC policy requires that specimens for testing be submitted through or with the approval of the state health department. Please contact your state health department, who will assist you with specimen submission and reporting of an infected patient. For general questions about RMSF, please call 1-800-CDC-INFO (1-800-232-4636). If you have questions about a suspect RMSF case, please first consult your state health department. Healthcare providers requiring an epidemiologic consultation on rickettsial diseases may also call 404-639-1075 during business hours (8:00 - 4:30 ET). Or 770-488-7100 after hours.
Non-U.S. Healthcare Providers
Non-U.S. healthcare providers should consult CDC prior to submitting specimens for testing. For general questions about RMSF, please call 1-800-CDC-INFO (1-800-232-4636). If you would like to discuss a suspect rickettsial case with CDC, please call 404-639-1075 during business hours (8:00 - 4:30 ET), or 770-488-7100 after hours.
