Vet tests positive to Hendra virus (this off the news.ninemsn website) 16:10 AEST Thu Aug 20 2009 A horse vet has tested positive to the deadly Hendra virus after an outbreak at a central Queensland stud. The vet, admitted to Brisbane's Princess Alexandra Hospital on Wednesday night, had treated horses that died from the virus at a Cawarral property. He is the seventh person ever to contract the virus. Queensland chief health officer Dr Jeannette Young said test results came back on Thursday morning. "One of the four suspected ... of getting a Hendra viral infection has been confirmed as positive," Dr Young said. She said the original tests of everyone who had any degree of exposure to the Hendra-affected horses on the property came back negative. "Should any of them develop symptoms they will (also) be tested on the spot," Dr Young said. "If they don't we will retest them three weeks after they last had exposure."
