West Nile Virus

Clinton and Wexford Counties, MI

Alert ID: 593

August 17, 2017

Source: Michigan Department of Agriculture and Rural Development

The Michigan Department of Agriculture and Rural Development has received confirmation that two additional Michigan horses have tested positive for West Nile virus (WNV). The two cases are as follows: a 10-year-old Belgian mare from Clinton County and a 21- year-old Quarter Horse mare from Wexford County. Both horses developed a sudden onset of neurologic disease including being down/unable to get up and were subsequently euthanized due to the severity of the disease. Neither horse had been vaccinated against WNV. This brings the total number of Michigan horses reported as having WNV in 2017 to seven, one each from the following counties: Clinton, Livingston, Jackson, Mecosta, Midland, Missaukee, and Wexford. No quarantines were issued.
