Seven tested after new Qld Hendra case 2:55pm July 7, 2013 Seven people are nervously waiting for test results after a horse infected with the deadly Hendra virus was put down in the Gold Coast hinterland. Queensland's Chief Veterinary Officer Rick Symonds says the unvaccinated horse was euthanased on Friday after becoming ill a day earlier. There are no more horses on the property, but Biosecurity Queensland has quarantined it to address environmental contamination. Seven people who came in contact with the horse are also being assessed. Other animals that might have been taken from the property will also be tested. "While under quarantine, restrictions will apply to moving horses and horse materials on and off the property," Dr Symonds said. "We will continue to contact trace to ensure no one else requires treatment." It is the fourth case of Hendra in Queensland this year. But it isn't related to the Hendra-related death of another unvaccinated horse in the Brisbane Valley in June, Dr Symonds said. "This second Hendra virus incident within two weeks highlights that most Hendra virus incidents occur in June to August, although they can occur at any time of the year," he said. "They are another reminder to horse owners that it is important for them to take steps year round to reduce the risk of Hendra virus infection." Biosecurity officers are expected to keep the property in quarantine for several more days.
