In a press release it was announced that a horse in Washita County passed away after contracting West Nile Virus.

Officials say a 4-year-old Quarter Horse gelding passed away last week and it was confirmed the horse had the virus on Wednesday.

West Nile virus is transmitted to horses via bites from infected mosquitoes. Not all infected horses show clinical signs, but those that do can exhibit various symptoms including flu-like symptoms, drowsiness, and weakness.

West Nile virus has no cure. However, some horses can recover with supportive care. Equine mortality rates can reach 30-40%.

Studies have shown that vaccines can be effective WNV prevention tools. Horses vaccinated in past years need an annual booster shot, but veterinarians might recommend two boosters annually—one in the spring and another in the fall—in areas with prolonged mosquito seasons.

It was not revealed where in Washita County the horse was owned.
