10 Facts About Equine West Nile Virus

West Nile Virus Facts

Your horse is part of your family, but unless he is vaccinated, he could be at risk for potentially deadly diseases like West Nile virus (WNV). As we prepare for mosquito season and the heightened risk of disease, be aware of these 10 important WNV facts.

Spring Vaccination Protect Against WNV

  1. Africa, Eastern Europe and West Asia have long experienced the impact of WNV; however, the disease is fairly recent to North America with the first case diagnosed in 1999.
  2. West Nile virus is transmitted by mosquitoes - which feed on infected birds - to horses, humans and other mammals.
  3. Horses represent 97 percent of all reported non-human mammalian cases of WNV disease.
  4. Infected horses begin to show signs of disease as early as three to 15 days.
  5. More than 25,000 cases of WNV have been reported in U.S. horses.
  6. The disease presents a 33 percent fatality rate to horses.
  7. Disease risk increased in 2018, with 384 cases of equine WNV reported - nearly 80 cases more than in 2017.
  8. Horses are at the highest risk for contracting WNV during peak mosquito season - July through October.
  9. When properly vaccinated, horses have shown to be 30 times less likely to contract WNV.
  10. Vaccination provides horses with nearly 100 percent protection against WNV.

Vaccinate your horse in spring, before the onset of mosquito season, to offer your horse the best protection available against West Nile virus. The vaccines, regardless of brand, will booster the protection. Remember, vaccination in conjunction with established mosquito management techniques are key to helping keep animals safe from this dangerous disease.
