Diagnostic Considerations

Failure to exclude the treatable tick-borne diseases (eg, Rocky Mountain spotted fever and relapsing fever) and other serious bacterial infections is a potential diagnostic pitfall.

Because this virus can be transmitted by blood transfusion, it is important to inquire into recent transfusions in patients with febrile illnesses (not just Colorado tick fever) and also to make sure that the patient does not donate blood for 6 months.
