The deadly illness has already claimed one life this year

A Victorian resident has been confirmed as the second human case of the potentially deadly Japanese encephalitis (JE).

Authorities say this person was exposed to the virus while in the Riverina region of NSW, on the Murray River.

The confirmed case comes not long after the first JE death this. NSW Health reported in February that a man in his 70s from northern Sydney died after battling the virus for several weeks. 

He was also infected while holidaying in the Riverina, and is the third person to lose their life to JE, since it was first detected in May 2022.

Health authorities are reminding Back Country residents that a free vaccination is available for people aged two months or older who live or routinely work in several local government areas, including Carrathool, Hay, Balranald and Central Darling Shire.

JE is a rare virus, similar to dengue and yellow fever, which is spread by mosquito bites and causes swelling in the brain. 

The fatality rate of those with severe JE can be as high as 30 per cent.

If you are eligible for a free JEV vaccine, speak to your General Practitioner (GP), pharmacist or Aboriginal Medical Service about getting vaccinated today.

NSW Health says residents should make an appointment with their GP, pharmacist or Aboriginal Medical Service and let them know it is for the Japanese encephalitis vaccine as they may require a few days' notice to order the vaccine.
