The expanding range of the lone star tick increases the risk of alpha-gal syndrome for more Americans, particularly in newly affected regions like the Great Lakes and parts of the Northeast. Those bitten by the tick may develop severe allergic reactions to red meat and certain dairy products, with symptoms ranging from mild hives to life-threatening anaphylaxis. The condition can also lead to dietary restrictions and potential complications with medical products derived from mammals. While the allergy may fade in some individuals over time, avoiding further tick bites is critical to prevent recurrence.
