Tick bites can cause Alpha-gal Syndrome, leading to allergies to red meat in up to 450,000 Americans.
A tick bite, particularly from the lone star tick in the US, can trigger Alpha-gal Syndrome (AGS), an allergy to red meat and other mammal products.
This occurs because the tick carries a sugar molecule, alpha-gal, not found in humans.
Symptoms range from mild to severe anaphylaxis, with potential breathing difficulties and loss of consciousness.
The CDC estimates 450,000 Americans may be affected.
Prevention involves avoiding tick bites by wearing protective clothing and using DEET repellents.
Diagnosis includes blood tests for alpha-gal antibodies, and management typically means avoiding red meat and sometimes dairy.
