Hepatitis E Virus and Porcine-derived Heparin
Highlights
To the Editor: Birge and Sonnesyn report the first death of a Minnesota resident caused by Powassan virus (POWV) (1)
Few POWV infections are identified by lineage; Minnesota’s first case in 2008 was identified as a deer tick virus infection, but the lineage was unknown for the other 16 cases
Many case-patients had likely exposure to Ixodes scapularis ticks, the tick species associated with deer tick virus transmission, and viruses from all POWV-positive tick pools were confirmed as deer tick virus by sequencing
