While we, in the U.S., always need to keep aware of diseases in other countries because they manage to always end up here, this doesn't seem to be something I need to have a panic attack over, anytime soon.
In terms of level of worry, mine start with rabies, tetanus, EPM, the various encephalitis, WNV.
At least that's how I feel if there is any credence to this article, which was updated 08-06-13, according to the web page. What is Hendra virus?
Hendra virus is a zoonotic disease, which means it can transfer from animals to people.
Hendra virus can cause disease in horses but only rarely in humans. It can be transmitted from flying fox to horse, horse to horse, and horse to human.
There is no evidence that the virus can be transmitted from flying fox to human, or human to horse, or human to human.
Flying foxes are a natural reservoir for Hendra virus. Flying foxes do not show any signs of illness when infected with Hendra virus.
Although Hendra virus infection is periodically present in flying fox populations across Australia, the likelihood of horses becoming infected is very low.
The potential seriousness of Hendra virus infection for both humans and horses requires that workplace health and safety measures, to prevent infection, should be implemented at workplaces where there is occupational contact with horses. Sound hygiene and biosecurity measures should be adopted as a routine practice for all horse contact.
It is not yet time for U.S. horse owners to have a panic attack unless our vets or the CDC know something they're not telling us
