Horse flu 'battle not over'

Queensland Racing says the battle against the equine influenza is not over despite a drop in the number of infected properties in the state's south-east.
Spokesman Malcolm Tuttle says more than 1600 properties are still in quarantine, a drop of about 600 from November.
He says the virus is still being spread through the horse population that have not had the flu or been vaccinated.
Mr Tuttle says unauthorised people should stay away from horses.
"If the status of the horse and the property is unknown we shouldn't be taking for granted that the horses are either resolved or the property is resolved," he said.
"It could well be that the horses that are being patted or handled may in fact have the disease and may be in a position where they're shedding the disease."
