Rising Tick Cases in Illinois Due to Shifting Weather Conditions

Scientists and researchers are observing a worrying trend with ticks in Illinois. The tick season may be arriving sooner, lasting longer, and affecting more areas. Milder winters and earlier springs are enabling better survival rates for ticks. Medical professionals have noted an uptick in cases of tick-borne diseases earlier this year compared to previous seasons.

Ticks are not just limited to dense forests anymore. Increasingly, they are found in urban parks, green areas, and suburban yards. Dr. Kelly Cairns from the Chicago Veterinary Medical Association emphasizes that ticks disregard city boundaries.

“Ticks aren’t confined to camping trips. They’re expanding their reach into urban environments,”

Tick season typically spans April through September. But warmer temperatures across all seasons due to human-driven climate change have altered this timeline. Experts highlight that winter temperatures are warming more significantly than other seasons. Especially noticeable in the Midwest and Northeast, shorter winters are allowing tick populations to grow.

Patrick Irwin, the lead entomologist with the Northwest Mosquito Abatement District, discussed how climate change seems to facilitate better survival and earlier activity for ticks.

“With climate change, ticks can survive better and become active earlier.”

Below 40 degrees, ticks go dormant. They hibernate beneath leaf litter and snow but start dying when temperatures fall below 14 degrees. This year, cold spells were paired with snow, insulating ticks from the severe cold. Above-average temperatures in February, March, and April allowed ticks to emerge sooner. Irwin’s observations recorded nearly seven times more deer tick sightings compared to last year.

On a personal note, social worker Ann Miller shared her experience. She discovered a tick on her dog Millie after visiting her mother’s home. Millie subsequently tested positive for Lyme disease. Though initially, bloodwork indicated she didn’t need antibiotics, symptoms later showed the infection was progressing.

Miller noticed changes in Millie’s behavior in May. Unusual limping and fatigue prompted further tests, confirming active Lyme disease. Antibiotic treatment resulted in symptom improvement. Miller reflected on awareness regarding ticks, realizing bites can occur earlier than anticipated.

“I didn’t think to start flea and tick prevention so early. This year, we began Millie’s medication much sooner.”

Dr. Cairns advises that the best protection for pets involves preventative medication and regular tick checks. She stresses that quick action is necessary if ticks are found.

Ticks latch onto hosts through questing, sitting in vegetation with legs outstretched. They thrive in shaded, humid environments like leafy piles. Feeding can last days during which time diseases like Lyme can be transmitted. Occasionally unnoticed due to their size, ticks pose a significant challenge.

Typically, Illinois reports about 300 confirmed Lyme disease cases annually. But non-recall of tick bites and flu-like early symptoms mean many cases go unreported. The Illinois Department of Public Health observes a growing trend in tick-borne disease cases.

Nationwide, the Centers for Disease Control and Prevention noted increased emergency room visits for tick bites in April. These rates were significantly higher than normal for this time of year.

Laura Sislow, a resident of St. Charles, shared her long-term battle with Lyme disease. Diagnosed after years of unexplained fatigue, the illness altered her life significantly, forcing her to abandon her career. The enduring symptoms include brain fog and joint pain, with no confirmed cause for prolonged issues.

“Lyme disease leaves you feeling like a shell of yourself.”

For tick bites, public health advice focuses on prevention. Protective clothing, repellent use, and post-activity tick checks are crucial.

Dr. Ihab Ahmed, an infectious disease physician, advocates prevention over treatment.

“Avoid tick-borne illnesses by preventing bites altogether.”

Light-colored clothing, socks tucked into pants, and even tape to deter ticks are recommended. Practical if not fashionable, these measures significantly reduce bite risk.
