What is alpha-gal syndrome? Know the signs, prevention of emerging condition

Key Points:

• Alpha-gal syndrome is a food allergy triggered by tick bites, causing the body to react to alpha-gal sugar found in most mammal meats, leading to symptoms like hives, nausea, and potentially life-threatening allergic reactions.
• The condition is difficult to diagnose due to delayed symptom onset, often occurring several hours after consuming meat, and it can also cause reactions to pharmaceuticals, vaccines, and animal-based products containing alpha-gal sugar.
• The Lone Star Tick is the primary carrier in the U.S., including Michigan where the tick population is growing, increasing the risk of alpha-gal syndrome, though the condition is not currently tracked as a reportable disease in the state.
• Prevention focuses on avoiding tick bites by wearing protective clothing, using EPA-approved repellents, maintaining yards to reduce tick habitats, and performing thorough tick checks after outdoor activities.
• Alpha-gal syndrome affects an estimated half a million people in the U.S. and remains relatively unknown; testing is becoming more accessible, but there is no current cure or treatment for the condition.
