An Illinois resident became “seriously ill” after being infected with Powassan, a tick-borne illness that has never been detected in the state before, the state health department said.
Health officials are investigating whether the person caught the virus in Illinois and are testing ticks for Powassan and other infections in areas of the state where the resident had been before their illness.
Meanwhile, the Illinois Department of Public Health is urging residents to take precautions against tick bites, like wearing preventive clothing and checking themselves, their children and pets for ticks after spending time outdoors.
“With warm weather still prevalent, tick-borne diseases remain a potential threat here in Illinois,” IDPH Director Dr. Sameer Vohra said in a Monday news release. “It’s important for everyone to guard against tick bites and the serious illnesses they can cause.
Cases of Powassan virus, although rare, have been on the rise in recent years, according to the Centers for Disease Control and Prevention. The Illinois health department said the virus poses a low risk to the general public with proper precautions.
Initial symptoms of the diseases may include fever, headache, vomiting and weakness, and the virus can cause severe diseases like inflammation of the brain and be fatal. Currently, there are no vaccines to prevent or medicines to treat the disease.
Anyone can develop severe disease if infected with the virus, but the CDC says older adults, children and those with weakened immune systems are most at risk.
IDPH also recommends residents avoid wooded, bushy areas, use insect repellent, shower and put clothes in the dryer to kill ticks after coming from outdoors, and seek medical attention immediately if showing symptoms.
