Hidden in the Grass: The Rising Threat of Powassan Virus

On a warm spring afternoon in the northeastern United States, a walk through tall grass can feel harmless, even restorative.

The Powassan virus is rare, but it is dangerous, and its quiet rise is reshaping how scientists think about tick borne disease, climate change, and neurological illness. In a recent review published in the journal Virulence, researchers Manpreet Kaur, Monica Adam, and Prof. Megan Mladinich Valenti bring together decades of scattered research to tell the evolving story of this virus and the risks it poses.
