Arboviruses (arthropod-borne viruses) of significance to the equine population are:

  • Eastern Equine Encephalitis (EEE)
  • Western Equine Encephalitis (WEE)
  • Venezuelan Equine Encephalitis (VEE)
  • West Nile Virus (WNV)

Infection is preventable with vaccination. Although WEE and VEE have not occurred recently in the US, vaccination should continue as risk of re-emergence exists.
