A 7-year-old girl presented with tiredness, muscle pains, chills, and low-grade fever (100.5°F). The girl enjoys playing outdoors, especially in the wooded areas of her backyard. Last week her mother noticed a black-legged tick attached to her inner right thigh, which she promptly removed. Approximately one week later, the girl began to feel unwell. Laboratory tests confirmed the diagnosis of human granulocytic anaplasmosis.

The child weighs 50 pounds and is an otherwise healthy child who does not take any prescription medications, OTC medications, or supplements. Furthermore, she has no known drug allergies.
