Another Horse Death as Hendra Spreads South

Another six people have been tested for the deadly Hendra virus after it claimed the life of a seventh horse, officials said Thursday, as the killer outbreak spread south.

At least 32 people have now been exposed to Hendra, a rare virus spread from horses which can cause fatal respiratory illness in humans, after a second case was confirmed in New South Wales.

"In NSW we now have single horse deaths to Hendra virus on two properties ... and 15 people who have been in contact with the affected horses," said the state's chief veterinarian, Ian Roth.

The latest outbreak, at Macksville, about 500 kilometres (310 miles) from Sydney, is the furthest south it has ever been detected, and only the third time Hendra has been seen in NSW.

One horse died and another three were being monitored, Roth said, adding that it was not believed to be linked to any of the other cases.

There have been three other outbreaks in Queensland state since June, exposing 17 people to sick animals.

A total of 32 people are now being tested for the virus.
