Fruit bats (flying foxes) are the
natural hosts of Hendra virus
How is Hendra spread?
• It is thought that Hendra virus is transmitted from fruit bat to horse via feed contaminated with fruit bat urine, faeces or body fluids
• Hendra virus can be spread from horse to horse and horse to human through close contact with respiratory secretions and/or blood from an infected horse
If you are concerned about your horse:
- Consult your veterinarian immediately
- Isolate the sick horse straight away
