Nine horses have been fatally hit by EIA, also called swamp fever - and another four have tested positive for the disease. Show director Gerry McAuliffe confirmed that the event would begin as scheduled, since the disease has affected only a minuscule number of thoroughbreds.
A warning has been issued to all horse owners to get the blood samples of their horses tested for EIA. This is the first ever case of swamp fever in Ireland which is thought to have spread by the use of infected equine serum to treat another horse infection. The virus is not much of a danger to humans. Horses suffering this type of infection portray symptoms such as fever, minor hemorrhages in the mucous membranes, anemia, dependent swelling and death. Insects that suck blood from the horse spread the disease. The disease can also spread by the use of contaminated needles.
