In a tragic turn of events, Maine has recorded its first deadly case of Powassan virus this year, following the death of an individual from York County. The Maine Center for Disease Control and Prevention (CDC) confirmed the news on Thursday, highlighting the rarity of such cases in the United States.

Although two other cases of Powassan virus were reported in Maine this year, one each in Kennebec and Lincoln counties, fortunately, both patients managed to recover from the infection. The last fatality caused by this tickborne virus in Maine occurred in May of the previous year.

According to the CDC, Powassan virus cases are considered rare across the nation, with an estimated 20 to 50 cases reported annually between 2018 and 2023. However, Maine has experienced a higher incidence, identifying a record-breaking seven cases of Powassan in 2023 alone. Since 2014, the state has recorded a total of 25 infections, resulting in four deaths over the past decade. Alarmingly, two of these deaths have occurred within the last 13 months.

Powassan virus is transmitted through the bite of an infected deer or woodchuck tick. These ticks can remain active as long as the temperature is above freezing but are most active during spring, summer, and fall. It is worth noting that the virus can be transmitted to humans within as little as 15 minutes after a tick bite.

While many individuals infected with Powassan virus may not exhibit any symptoms, those who do develop symptoms can experience them up to a month after being bitten by an infected tick. Common signs include fever, headache, vomiting, weakness, confusion, seizures, and memory loss. In some cases, the virus can result in severe neurologic problems, such as brain or spinal cord inflammation. It is estimated that around 10% of individuals with severe disease succumb to the illness. Additionally, individuals with weakened immune systems are at a higher risk of developing severe symptoms.

As the first documented fatality from Powassan virus in Maine this year, this tragic incident serves as a solemn reminder of the potential dangers associated with tickborne illnesses. It underlines the importance of taking preventive measures, such as wearing protective clothing, using tick repellents, and conducting thorough tick checks after spending time outdoors. Immediate medical attention should be sought if symptoms of Powassan virus or any other tickborne illness arise.

Maine's health authorities will continue to monitor and investigate cases of Powassan virus in order to provide necessary guidance and support to the public.
