For two decades, a perplexing illness has been spreading: After a lone-star tick bite, people find themselves with a severe allergic reaction to red meat. The CDC estimates up to 450,000 people in the U.S. may be affected with alpha-gal syndrome, up from just a few dozen documented cases in 2009. New research finds that in some states, more than 30% of people are positive for alpha-gal antibodies—but not all of them have the syndrome.
Flora speaks with allergist Scott Commins, who has studied alpha-gal syndrome for nearly 20 years, to unpack this finding and next frontiers for treatment.
Guest:
Dr. Scott Commins is the William J. Yount Distinguished Professor of Medicine and associate chief for allergy and immunology at the UNC School of Medicine in Chapel Hill, North Carolina.
