Hendra Virus occurs naturally in flying foxes in Australia. Occasionally unvaccinated horses get infected with Hendra virus as a result of feed or water contamination by flying foxes.
Around 100 horses have died from the infection over the past 20 years, mostly along the east coast from the mid north coast of NSW north to Cape York.
But Hendra virus is also a dangerous human health hazard. Four people have died from contact with infected horses since the disease was first discovered in 1994.
An effective vaccine to protect horses against Hendra virus infection is available; horses need regular boosters to maintain protection.
