Similar symptoms are seen in anaplasmosis as that of Rock Mountain spotted fever (RMSF) and erhlichiosis:
- Shaking chills
- Severe headache
Most cases of anaplasmosis are mild and self-limiting. However, the infection can be fatal if the patient is of an advanced age, immunosuppressed, has a malignancy, or a chronic inflammatory disease. Rash is seen in 60% of children, but only 30% of adults.
