Vaccines for four people who came in contact with bat-borne lyssavirus in Queensland AT LEAST four people who came into contact with a horse infected with the bat-borne lyssavirus in Queensland have chosen to undergo preventative treatment. Tests have confirmed the first case of the rare virus in a horse, which was put down at an equestrian centre owned by former Wallabies and Queensland Reds team doctor Cameron Osborne last Saturday. Another horse with similar symptoms was euthanased on the same property a fortnight ago. Dr Osborne says he and three fellow workers at Highborne Farm, north of Warwick, in the state's southwest, are undergoing treatment. He says others, who don't work on the property, but came into contact with the sick horses may also be undergoing vaccinations. "Because of possible exposure to the lyssavirus we've been advised it's very wise to have a rabies vaccination," he told AAP on Sunday. Worldwide anyone who has been exposed to this virus, who have not had any signs of the illness and have followed through the vaccination have not developed the condition. He said vaccination began on Saturday and they will require three more injections over a fortnight. "It's not nerve-racking but it is concerning," Dr Osborne said. We are just following prudent biosecurity measures as we did when the horses began showing signs of being unwell. He said a third horse that was in the same paddock as the two sick horses had not contracted the virus. Up until now, the lyssavirus has only been known to infect humans from a bite or scratch from a bat. All three people to have contracted the virus in Australia, all in Queensland, have died.
