[IMJ On-Air] A tiger in the mallee: Victoria’s JEV cluster

On the 28th of January 2022 a 75-year-old man was admitted to the regional Albury Wodonga Health Service with a high fever and Parkinsonian symptoms. The patient spent over a week in intensive care, but brain scans did not reveal an obvious aetiology and assays for a range of pathogens came up negative.When serology eventually revealed the presence of antibodies against Japanese encephalitis virus this became only the second ever locally-acquired case on Australia’s mainland. Even more startling was the fact that the previous one had been way back in 1998 in Cape York, far north Queensland. The Victorian patient was the first what would become an outbreak of 43 symptomatic human cases that resulted in six deaths. The JE virus would be detected in all mainland states and retrospectively linked to another fatality in March 2021 from the Tiwi islands of the Northern Territory. In this podcast we hear about the confluence of factors that brought a classically tropical disease to the southern states. The story is told from the perspective of the treating clinicians, microbiology specialist and public health physician who started putting the puzzle together from four sentinel cases.
