Two horses in Illinois diagnosed with equine herpes virus

WARRENVILLE, Ill. (AP) — State agriculture officials say two horses from a northeastern Illinois stable tested positive this month for the contagious equine herpes virus.

Other horses at the same stable had symptoms of the virus. State veterinarian Mark Ernst says two horses have been euthanized and a third has shown neurological problems from the infection. The virus commonly known as EHV-1 can cause respiratory problems, abortion, neurological disease and death in newborns. Humans are not at risk.

The Chicago Tribune reports that horse shows have been called off in the area to curb spread of the disease.

Ernst says the infected horses were performing at a show May 2-3 in Gifford in east-central Illinois when they showed symptoms. The facility that hosted that show has closed for three weeks to disinfect.
