From The Horse
July 19, 2022
The California Department of Food and Agriculture confirmed a 4-year-old unvaccinated Quarter Horse gelding in Kern County, California, positive for West Nile virus (WNV) on July 11. On July 2, he presented with acute pelvic limb ataxia (incoordination) that progressed to recumbency (down and unable to get up), and fever. The horse has been euthanized due to the severity of his signs. The boarding facility where he resided is not currently under quarantine.
This case marks California’s second confirmed horse with WNV in 2022.
