The warm, sunny days of fall, coupled with sporadic rain, have created ideal conditions for ticks to flourish in Pennsylvania. As tick season intensifies across the U.S., officials are raising awareness about a rare but potentially life-threatening disease linked to ticks.
Powassan virus, though extremely uncommon, is a serious illness that is transmitted through the bite of infected black-legged deer ticks, as noted by health authorities in Massachusetts.
If a tick carrying the virus bites someone, the transmission can happen in just minutes, targeting the brain and possibly leading to severe complications like encephalitis, difficulty speaking, seizures, and even paralysis, according to information from the Cleveland Clinic.
“One of the most alarming aspects is how quickly it spreads,” Dr. Jorge P. Parada, a medical advisor for the National Pest Management Association in Chicago, explained. He mentioned that, unlike Lyme disease—which generally requires a tick to be attached for 36 to 48 hours before transmission—Powassan can infect a person within about 15 minutes.
Initial symptoms of the Powassan virus may manifest as fever, headaches, vomiting, and fatigue. Those who recover might still suffer from long-lasting effects, including chronic headaches, memory issues, and decreased muscle strength.
“Unlike most tick-borne diseases, around 10% to 15% of severe cases can be fatal,” Parada added. “And nearly half of those who survive may deal with permanent neurological damage.” Even though it’s pretty rare, there has been a noted increase in cases in recent years.
Since 2012, approximately 200 cases have emerged across the U.S., with fewer than ten reported so far this year.
A recent case involved John Reagan from New Hampshire, who was diagnosed with the Powassan virus about a month ago. Reports say he was hospitalized after contracting the disease and has since lost his ability to speak clearly, needing a ventilator to breathe and a feeding tube for sustenance. Friends have described him as previously very active.
“Every day is both a challenge and a miracle as John continues to battle this devastating illness,” a GoFundMe page for his family shared. They also highlighted the emotional and financial strain the situation has created for his loved ones, particularly with the growing medical expenses while he remains hospitalized.
At this point, there’s no specific treatment available for Powassan virus, and severe cases may result in long-term complications. Health experts emphasize that older adults, young children, and individuals with weakened immune systems face the highest risk.
Cases typically rise from late spring through mid-fall when ticks are most active. To reduce the chances of infection, the CDC suggests using insect repellent, wearing long sleeves and pants, avoiding overgrown areas when possible, and conducting thorough tick checks after spending time outdoors. In addition, making your yard less appealing to ticks by keeping grass trimmed and using gravel or wood chips can deter their movement.
