Risk of EHV

The equine herpes virus is transmitted in various ways.

  1. Horses breathe in the virus from infected horses – shedding via the respiratory system can last for 7 to 10 days1
  2. The virus can be spread indirectly when secretions from an infected horse (either from their nose or due to an abortion, which results in infected tissue and fluids) are transmitted by people or by sharing equipment1

Minimising risk

There are steps you can take to minimise the risk of equine herpes virus.

  • If your horse has been diagnosed with herpes, ensure your horse is isolated for about 28 days, or as long as your vet recommends.1
  • Always wash your hands after touching an infected horse.1
  • Don’t share equipment among your horses.1
  • If an abortion has occurred, ensure you don’t spread the virus via your hands or equipment – remember that the virus is found in the aborted animal and in fluids and tissue such as the placenta, as well as via the respiratory system of the mare.1
