alpha-Gal Syndrome Cases Surge Across teh U.S., Linked to Tick Bites
A recent study reveals a dramatic increase in cases of alpha-gal syndrome (AGS), a rare but increasingly prevalent condition causing allergic reactions to red meat, across the United States. The syndrome, triggered by bites from the Lone Star tick, is spreading beyond it’s historically concentrated areas in the Southeast and Mid-Atlantic, raising concerns among health officials and prompting a need for greater awareness.
Alpha-gal syndrome occurs when a tick bite transmits a sugar molecule called alpha-gal into a person’s body. This can lead to delayed allergic reactions – often several hours after consuming beef, pork, or lamb – ranging from hives and itching to severe anaphylaxis. The condition impacts an estimated 4,500 to 22,000 Americans, but experts believe the actual number is significantly higher due to underdiagnosis. The surge in cases is attributed to the expanding range of the Lone Star tick, driven by factors like climate change and wildlife migration.
Hayden hurtig, diagnosed with AGS during middle school, shared his experience with Nexstar’s WDAF, detailing allergic reactions following red meat consumption.After avoiding red meat for approximately seven years, Hurtig found he was able to eat it again, following a doctor’s proposal to eliminate it completely from his diet. “The more you eat it, the more it feeds it and [getting over it] will take longer,” Hurtig explained, relaying his physician’s advice.
Health officials emphasize that preventing tick bites is the most effective way to avoid AGS. Protective measures include using insect repellent containing at least 20% DEET,picaridin,or IR3535,wearing long sleeves and pants when outdoors,and avoiding areas with tall grass and leaf litter. The U.S. Forest Service recommends showering or bathing quickly after being outdoors and conducting thorough body checks for ticks.
The Centers for Disease Control and Prevention (CDC) is currently working to improve AGS surveillance and diagnostic capabilities, as well as educate both the public and healthcare providers about the condition.As the Lone Star tick continues to expand its territory, vigilance and preventative measures are crucial in mitigating the growing impact of this unusual allergy.
