Equine Infectious Anemia confirmed in Maryland

Equine Infectious Anemia confirmed in Montgomery County

July 10, 2018

 

Farm Placed Under Investigational Hold Order

ANNAPOLIS, MD – A horse stabled in Montgomery County has tested positive for Equine Infectious Anemia (EIA). The positive horse was discovered during a routine wellness examination by a private veterinarian and was confirmed positive July 9 by the National Veterinary Services Lab in Ames, Iowa. The infected horse will be euthanized. EIA is not known to effect human health.

The State Veterinarian’s office has placed the farm under a 60-day investigational hold order. The department will do initial EIA tests on the remaining 42 equines on the farm. The animals will be tested again after 60 days, at which point the hold order will be released barring any positive test results.

Equine Infectious Anemia is a blood borne virus typically transferred by biting flies or infected needles. The infected horse did not display any clinical symptoms, but was determined to be in the carrier stage of the disease. Confirmed cases of EIA typically result in euthanasia or lifetime isolation for the infected horse.

The department’s Animal Health Program will continue to monitor the situation closely, and reminds all horse owners to remain vigilant in protecting the health of their animals—this includes routine disease testing. More information on EIA is available from USDA Animal and Plant Health Inspection Service.
