Powassan is a virus that can be spread to humans through the bite of an infected tick.

Cases of Powassan virus have hit the news in recent months because of the potentially life-altering, sometimes fatal, symptoms.

The 2.8-Å resolution structure is presented for a chimeric construct of an emerging tick-borne flavivirus, Powassan virus.

Health officials warn residents to take precautions.

The Rhode Island Department of Health announced that a Newport County man was diagnosed with Powassan virus disease, a rare tick-borne illness.

Powassan is transmitted through the bite of deer ticks, and infections can be severe, even fatal.

The rare tick-borne virus can lead to neurological conditions.

Powassan virus (POWV) was first isolated in 1958 from a child with a fatal case of encephalitis in Powassan, Ontario, Canada. POWV is an enveloped Orthoflavivirus with a single-stranded, positive-sense RNA of 11kb. Its genome encodes a single polyprotein that is cleaved into three structural (Capsid, pre-Membrane, and Envelope) and seven nonstructural proteins (NS1, NS2a, NS2b, NS3, NS4a, NS4b, and NS5). Although not as well studied, extrapolations from closely related Orthoflaviviruses, including West Nile and dengue, have contributed to our understanding of POWV replication.

Kevin Boyce, a 62-year-old resident of the Boston area, passed away last year from Powassan virus. Now, his family is raising awareness about the risks of

The virus is transmitted to people through infected deer ticks -- the same tick that spreads Lyme disease and other diseases.

Rates of the Powassan virus infections — which can cause seizures and paralysis — are increasing across North America. Researchers from Penn State, the University of Minnesota and the U.S. Department ...
