Man Died from Tick-Borne Virus After His ‘Brain Had Blown Up’. Now His Family Is Warning Others

In April 2024, Kevin Boyce was bitten by a tick and contracted Powassan virus, a rare but severe tick-borne illness. After developing flu-like symptoms, including headaches and vomiting, the 62-year-old collapsed and was rushed to Massachusetts General Hospital. Despite intensive care, the virus caused severe brain damage, and Kevin passed away weeks later.

Now, his family is sharing his story to raise awareness about the dangers of tick bites. “His brain had exploded from the encephalitis,” said Erin Boyce. “It was terrible, but we had to let Kevin go because we knew what he would want.”

Powassan virus (POWV) is uncommon, but cases have increased in recent years. In 2024, 54 cases were reported in the U.S., with 12 in Massachusetts. The virus causes symptoms like fever, headache, weakness, disorientation, seizures, and in severe cases, brain or spinal cord inflammation. Roughly 10% of severe cases are fatal, and there is no vaccine or treatment.
