The Equine Disease Communication Center (EDCC) reported Jan. 13 that equine infectious anemia (EIA) was confirmed in Illinois in late 2016.

“The Illinois State Veterinarian’s Office received positive EIA test results from a horse stabled in Northeast Illinois in mid-November,” the EDCC said. “Prior to the results being returned, the horse was removed from the premises and has been lost to follow-up.
