Research advances understanding of tick-borne Powassan virus

Research advances understanding of tick‑borne Powassan virus, a development noted amid broader concerns about expanding tick populations in the United States. The increase in tick numbers is linked to a rise in tick‑borne diseases, with Powassan virus identified as a rare but increasingly reported infection.

Powassan virus can cause severe brain inflammation and lasting neurological complications, underscoring the health implications of the growing tick threat. The research highlights the expanding risk posed by Powassan virus as tick populations spread across the United States.
