Three Michigan horses have been euthanized after testing positive for West Nile virus (WNV). On July 28 the Michigan Department of Agriculture and Rural Development received confirmation that those horses tested positive for West Nile virus. Those three horses are a 31-year-old Arabian mare from Jackson County, an 8-year-old Arabian gelding from Livingston County, and a 15-year-old Standardbred gelding from Missaukee County.
All three horses developed severe neurologic signs. Those signs included incoordination, sweating, right-sided facial paralysis, head pressing, paddling and an inability to stand. All three affected horses were euthanized. Their vaccination history is unknown.
The Equine Disease Communication Center works to protect horses and the horse industry from the threat of infectious diseases in North America. The communication system is designed to seek and report real time information about disease outbreaks similar to how the Centers for Disease Control and Prevention (CDC) alerts the human population about diseases in people.
