A little-known allergy linked to tick bites is drawing increasing concern across Southern Illinois, with health experts warning the condition can be life-threatening.
Known as Alpha-gal Syndrome (AGS), the illness can develop after a tick bite and causes an allergic reaction to red meat and other mammal-derived products.
Experts say the condition goes beyond food triggers. Dairy products, gelatin and even certain medications may cause reactions in those affected.
Symptoms can range from mild hives to severe, potentially life-threatening allergic responses. One of the challenges in diagnosing AGS is that symptoms often do not appear until several hours after consuming red meat, making it more difficult to connect the reaction to a specific cause.
Cases of Alpha-gal Syndrome are being reported more frequently across Southern Illinois and the surrounding Tri-State region.
According to health officials, the condition is most commonly associated with bites from the lone star tick, though in some cases it may also be linked to other tick species. Experts note that AGS differs from Lyme disease, where symptoms may appear within days or weeks—or sometimes not at all.
Shawnna Rhine with Rural Health Inc. said reactions tied to Alpha-gal are typically triggered after consuming red meats such as beef, pork, lamb and venison.
Health officials recommend taking precautions to prevent tick bites, including using insect repellent, wearing protective clothing and checking for ticks after spending time outdoors.
Experts also urge individuals to pay close attention to symptoms and seek medical care if they suspect a reaction.
