KAUFMAN COUNTY, Texas — The Texas Animal Health Commission (TAHC) has ordered another round of quarantines at a property where several horses previously tested positive for equine infectious anemia (EIA) — this after three more horses tested positive for the incurable and deadly disease.

In an October 19, 2019, bulletin, the Equine Disease Communication Center (EDCC) states the three horses tested positive for EIA at one Kaufman County premises, which previously confirmed positive EIA tests in September 2019. In this case, all positive horses have been euthanized and all premises will remain under quarantine until TAHC requirements are met.

"TAHC staff have worked closely with owners and veterinarians to monitor potentially exposed horses and implement biosecurity measures," read the bulletin.

In September, an EDCC bulletin identified three positive horses at one Kaufman County premises and another positive horse at a separate  Kaufman County premises. Both were quarantined on July 15, 2019. Those positive horses, too, were euthanized, according to EDCC.

In July 2019, 16 horses tested positive for EIA at one Kaufman County premises located southwest of Kemp, according to TAHC.

Its unknown which bulletin is related to which premises because the TAHC does not publicly release the addresses where the positive tests results are reported.

Equine infectious anemia is a viral disease, with no cure or vaccine, that attacks horses’ immune systems. Horses diagnosed with EIA are infected for life and typically die, are euthanized, or must be placed under very strict quarantine conditions for the remainder of their lives.

Although not all horses display signs of EIA infections, those that do can exhibit muscle weakness and progressive condition loss, poor stamina, fever, depression, and anemia.

The virus is transmitted through the exchange of bodily fluids through blood-contaminated medical instruments and needles as well as blood-feeding insects such as horseflies.

"There is no human health risk associated with EIA as this disease does not affect humans," stated the TAHC.
