The premises has been quarantined and will not be released until TAHC’s requirements are met. TAHC staff are working closely with the owner and local veterinarian to monitor potentially exposed horses and implement biosecurity measures.

EIA is an incurable, infectious viral disease spread through blood-to-blood contact, not through close proximity or direct contact. The virus can be transmitted from an infected equine to an uninfected or “clean” equine by biting flies, the use of unsterilized or contaminated medical instruments, or through a blood transfusion.

The most common clinical sign of acute EIA is fever, which often precedes the development of other signs. In chronic cases, symptoms such as weight loss, weakness, anemia and swelling of the lower legs, chest and abdomen may occur.
