"Murray Valley encephalitis was named after the Murray Valley region of Victoria, where the virus was first isolated from a deceased patient during an epidemic in 19511,5."
"The causative agent is MVEV, a single-stranded RNA flavivirus. Mosquitos and wild waterbirds, especially in the northern regions of Australia and in Papua New Guinea, are reservoirs for the virus, which is then spread by mosquitoes 1-3. Importantly, only 0.01-0.06% of patients with MVEV infection develop Murray Valley encephalitis 1."
"There is no specific antiviral treatment available for Murray Valley encephalitis, and thus supportive management (e.g. antiseizure medications, corticosteroids) is encouraged 1. Mortality is thought to be between 15-30%, with an additional 30-50% of patients having long-term neurological complications 1."

"Most patients have non-specific viral prodromal symptoms for approximately one week, including fevers, headache, nausea and vomiting, diarrhoea, and generalised macular rash 1-3. This is followed by the emergence of neurological features, such as confusion and generalised or focal seizures 1-3."
