A Maine resident has been hospitalized with the year’s first human case of the tick-borne Powassan virus, Maine officials said Tuesday.

The adult resident of Hancock County was infected with the virus and developed neurological symptoms, prompting hospitalization, the Maine Center for Disease Control and Prevention announced Tuesday afternoon.

Meanwhile, the agency also says the season’s first wild bird case of another tick-borne disease — the West Nile virus — has been detected in a crow in York County.

Maine CDC tests wild birds during mosquito season to determine whether viruses are circulating in the state before they spread to humans and domesticated animals.

While many people infected with either Powassan or West Nile virus do not get sick, the CDC noted that fever and flu-like illness can develop, while rarer but more severe symptoms can include seizures, memory loss, and brain or spinal cord inflammation.

About 10% of people with severe Powassan disease die, according to the CDC, while many survivors have to reckon with long-term symptoms ranging from headaches to memory problems.

“Treatment for both Powassan and WNV is supportive, aimed at managing symptoms and complications,” the CDC’s announcement states. “If you experience these symptoms, call a health care provider or seek medical attention.”

Cases of another tick-borne illness, Lyme disease, are on pace to break records, with nearly 2,000 cases already reported in Maine this year. Cases of anaplasmosis, the second-most common tick-borne disease, are also skyrocketing.

The CDC says the best protection against these diseases is simply to prevent tick and mosquito bites from occurring in the first place. The agency recommends wearing clothing that covers the arms and legs, tucking pants into socks, and using bug repellent. Anyone outside at dawn or dusk should be extra careful and check for ticks regularly.
