Reports that the deadly Hendra virus may have spread to Sydney these days have seen the city's largest racetrack shut down and the city in a state of shock. Officials have cordoned off Sydney's Royal Randwick Racecourse after a horse began exhibiting possible Hendra symptoms.
The horse was reported to be showing signs of colic, shifting weight on its forelegs, salivation and fever.
It also showed subtle neurological signs, including "mild depression", and muscle tremors. The horse in question has been tested and while the results have come back negative, the racecourse remains in lockdown as officials scramble to ensure safety precautions are in place.
The Hendra virus is deadly to humans and horses and there is no known cure.
The latest Hendra outbreak to strike Australia began two weeks ago, killing three horses in northern New South Wales after spreading from Queensland. This most recent emergence has now killed seven horses in five outbreaks across the north of Australia.
Its arrival, so far south in Sydney, would be unprecedented.
Its movements, the way it spreads and its causes, are still relatively unknown, although there is evidence that its origin may be from colonies of flying foxes, a kind of fruit bat that is flourishing on Australia's eastern coast.
