Ehrlichiosis is a tick-borne infection that has become increasingly more common in the United States in recent years. We present a case of a patient who was found to have confusion, hyponatremia, and hemophagocytic lymphohistiocytosis after contracting Ehrlichia chaffeensis following a tick exposure. This unusual presentation emphasizes the need for increased awareness of the varied symptoms of this infection and the importance of obtaining a complete history from patients at risk of vector-borne diseases.
Keywords: ehrlichia chaffeensis; ehrlichiosis; hemophagocytic lymphohistiocytosis; tick-borne diseases; zoonoses.
