Powassan Meningoencephalitis, New York, New York, USA
Powassan virus (POWV), a rare neuroinvasive arbovirus, was first described in 1958 (1,2). POWV has been isolated from Ixodes ticks; implicated hosts include woodchucks, red squirrels, chipmunks, groundhogs, and white-footed mice (1–4). Symptoms of infection vary from mild myalgia to acute flaccid paralysis and neurologic involvement. In the United States, POWV has been reported in northeastern and north-central states, and incidence is increasing (3,4). We describe the clinical characteristics and outcomes of 2 patients with POWV in New York, New York, USA.
