MELFORT, Sask. — An outbreak of Japanese encephalitis in Australia is causing worldwide concern.
The viral zoonotic disease is spread by mosquitoes and can cause reproductive losses and encephalitis in pigs and horses. In rare cases the disease can appear in humans.
Australia’s Sun Pork Group veterinarian Dr. Kirsty Richards said while people and horses are considered ‘dead end’ hosts and do not play a role in transmitting the virus, pigs and some species of wild birds can spread the disease.
She said the virus was found in the far northern tip of the state of Queensland but that changed suddenly just over a month ago when within 24 hours the virus was diagnosed at unrelated pig farms across New South Wales, Victoria, and Queensland.
