CDC Finds 24% Alpha-Gal Exposure in 5 States as Tick-Borne Meat Allergy Risk Spreads
3 articles · Updated · NBC News · Jul 2
Summary
About 24% of adults in Arkansas, Kentucky, Missouri, Tennessee and Virginia had alpha-gal antibodies in a CDC analysis of 3,000 blood donors, signaling prior exposure from tick bites.
Those antibodies do not mean a person has alpha-gal syndrome, researchers said, but they show likely contact with ticks that can trigger the red-meat allergy after feeding on mammals carrying the alpha-gal sugar.
The CDC has estimated roughly 450,000 Americans may have alpha-gal syndrome, yet the true prevalence is unclear because only a few states require case reporting and the condition is not nationally notifiable.
Researchers and advocates say cases are likely to rise beyond the East and Midwest as lone star ticks and other implicated species expand westward and northward with warmer winters and shifting deer populations.
With exposure rates soaring, why do only some people develop the alpha-gal red meat allergy?
As this lifelong meat allergy spreads across America, why isn't it tracked like other diseases?

Overview
Alpha-gal Syndrome (AGS) is becoming a major public health concern in the United States, with its rise closely tied to the spread of certain tick species. Recent research, based on blood samples from 3,000 adults across 10 states, shows that people living in areas with many lone star ticks are much more likely to have been exposed to alpha-gal. This means the geographic spread of AGS matches where these ticks are found. The report highlights that understanding tick distribution is key to predicting and managing the growing challenge of AGS.
