Alpha-gal syndrome is rising in Illinois, expert says
NBC Chicago • • health
Key Points:
- Cases of alpha-gal syndrome, a life-threatening meat allergy caused by lone star tick bites, are increasing in Illinois as the tick expands its range in the Midwest, with symptoms including hives, diarrhea, and difficulty breathing.
- The allergy develops when tick bites introduce alpha-gal sugar into the bloodstream, triggering an immune response that causes allergic reactions hours after consuming mammalian meat or dairy products.
- Climate change and rising temperatures are contributing to the spread of various tick species in Illinois, leading to more tick-borne diseases and concerns about new endemic illnesses.
- The Illinois Department of Public Health and experts warn of a potential second wave of tick season in the fall, driven by blacklegged ticks becoming active again, particularly in northern Illinois.
- Treatment has traditionally focused on avoiding mammalian meat and carrying epinephrine, but the first drug for alpha-gal syndrome has recently been approved, offering new hope for patients.
