Papers of the Week

Powassan virus is a rare flavivirus that may be transmitted by tick bite and is associated with encephalitis. Infections have been described in the northern United States, Canada, and Russia. We present the case of a 56-y-old man who presented to our hospital with symptoms of confusion, altered behavior, and headache. The patient developed fever and status epilepticus despite supportive care and required endotracheal intubation. Six days before presentation, the patient had returned from a hunting trip in the Adirondack region of New York State.
