Research advances understanding of tick-borne Powassan virus

New research is shedding light on Powassan virus, a rare but increasingly reported tick-borne infection that can cause severe brain inflammation and lasting neurological complications. As tick populations expand across the U.S., cases of Powassan virus and other tick-borne diseases are rising, making early detection and understanding critical for patients. The virus can lead to encephalitis, potentially causing long-term neurological damage. This research is important for healthcare providers and residents in affected regions, particularly in the Northeast and upper Midwest, to recognize symptoms and seek prompt medical attention.
