NSW: Notice to Industry - Hendra Virus

08 October 2021

Hendra Virus has, this week, been reported on a property at West Wallsend in the Newcastle area in 7 year old unvaccinated clydesdale. It is particularly noteworthy as it represents the most southerly latitude that known Hendra Virus cases have been diagnosed.

Hendra virus infection has the potential to affect both horses and humans. It has the potential to be life threatening. The natural hosts of Hendra virus are fruit bats (flying foxes), which have the potential to pass the infection to horses via their faeces and bodily fluids. Human infection can arise given exposure to the blood, bodily fluids and tissues of an infected horse. There is no evidence to date to support the spread of disease from human to human or bat to human. There is, however, evidence of spread from horse to horse, following the exposure to the secretions of an infected horse.

Signs of Hendra Virus infection in horses include:

  • Acute onset of illness
  • Increased body temperature
  • Increased heart rate
  • Discomfort/ weight shifting between legs
  • Depression
  • Rapid deterioration of well-being and clinical signs

The NSW Department of Primary Industries has provided the following advice for horse owners:

1.    Horse owners are encouraged to vaccinate horses for Hendra Virus;
2.    Horse paddocks containing fruiting or flowering trees (or other trees that attract bats) should be             fenced off so horses do not camp under them;
3.    Horse feed and water containers should be located under cover away from bat faecal and spat             contamination;
4.    Isolate sick horses from humans and other animals and wear personal protective equipment if             required to handle a sick horse.

Owners of horses in at risk areas are strongly advised to contact their veterinarian as vaccination remains the single most effective method of preventing infection from this deadly disease.
