Tick Season Brings a Grave Threat: The Powassan Virus

As tick season kicks off, a serious and often underestimated health threat looms—the Powassan virus. Though a rarity in Minnesota compared to other tick-borne illnesses, this virus is notably severe, leading to significant neurological damage and, in rare cases, even death, according to Elizabeth Schiffman, the epidemiologist supervisor at the Minnesota Department of Health (MDH).

Record Highs and Concerning Trends

In 2022, Minnesota reported 14 cases of Powassan virus, the highest since recordkeeping began in 2008. The first recorded death from this virus occurred in 2011 when a woman in her 60s tragically succumbed to a brain infection. These numbers highlight a growing trend that begs for increased awareness.

Mild Symptoms Can Hide a Serious Threat

While the overall risk of contracting the virus is deemed low, many infected individuals may exhibit mild or no symptoms at all. Common signs include fever, headache, vomiting, and weakness. However, severe cases can escalate to seizures and swelling in the brain, primarily affecting the elderly and those with weakened immune systems.
