LANSING, Mich. Michigan officials have issued quarantines for about two dozen horses in four counties following the death of a horse with a strain of equine herpes virus.
The Kalamazoo Gazette reports the barrel-racing horse in Livingston County had EHV-1, but no other horses have tested positive for the deadly neurological form of the disease.
The Michigan Department of Agriculture and Rural Development issued quarantines involving about 22 horses in Barry, Ionia, Livingston and Saginaw counties. The Livingston County horse that tested positive was euthanized on March 21 after its condition worsened.
Michigan horse owners are being urged to vaccinate their animals and isolate any that might have had contact with the animal.
The disease poses no harm to humans but can cause abortions, partial paralysis and death in horses.
