Equine Disease Alerts: August

EIA Kills 4 More Texas Horses

McLennan, Wilson, and Ector Counties, Texas

August 14, 2018


Texas officials confirm two horses at a quarantined McLennan County premises tested positive for equine infectious anemia (EIA). A veterinarian euthanized both horses. The Texas Animal Health Commission (TAHC) quarantined that facility in July after a Quarter Horse tested positive for EIA.

Additionally, a horse located at a Wilson County quarantined premises tested positive for the contagious disease sometimes known as swamp fever. In June, TAHC officials say two horses there were confirmed positive for EIA. Veterinarians destroyed those three horses.

Another county is now on the EIA map – Ector County. That’s because a Quarter Horse at a farm there was confirmed positive. The three locations remain under quarantine and potentially exposed horses are being monitored.

Officials stress good biosecurity practices to help prevent the blood-borne disease. There is no cure or vaccine for the prevention of the disease.



Equine Infectious Anemia (EIA) Deadly for Georgia Horses

Lamar County, Georgia

August 6, 2018


Georgia officials confirm three horses in Lamar County tested positive for equine infectious anemia (EIA). A veterinarian euthanized the horses since there is no cure for the blood-borne disease.

The Georgia Departmartment of Agriculture confirms another state’s EIA trace identified the infected horses. Furthermore, this is an ongoing case and investigation also involving the USDA, Julie McPeake a spokeswoman for the state agency tells us.

Officials quarantined the herd and will follow-up in 60-days.

The disease, also called swamp fever, affects horses, donkeys, and mules. Additionally, there is no vaccine to prevent EIA. Biting insects typically transmit EIA although the use of infected needles can also transmit EIA from equine to equine.

EIA reaks havoc on the equine immune system. Clinical signs of EIA include fever, weakness, weight loss, anemia, edema, and death.

To help prevent the disease, veterinarians recommend insect control, good horse facility sanitation and testing new equine residents with a Coggins test before bringing them onto your property.

All infected equines, even those that are asymptomatic are carriers of the disease.

Quarantining new equines for 45 days, away from current equine residents, is necessary to keep a healthy stable of horses. That’s because affected equines can carry the disease without symptoms for years.
