NSW Health is urging the community to take precautions against mosquito bites after a fourth NSW resident was confirmed to have Japanese encephalitis (JE).
The confirmed case is a woman aged in her 60s who spent time in the Griffith region before the onset of her illness. She was treated in hospital before being discharged recently and she is continuing to recover at home. This is the second confirmed case who has spent time in the Griffith region.
Several more people in NSW are currently undergoing further testing for JE and more cases are expected to be confirmed over the coming days and weeks.
Locally acquired cases of JE have never previously been identified in NSW in animals or humans. Since late February 2022, the JE virus has been confirmed in samples from pig farms in NSW, Queensland, Victoria and South Australia.
The JE virus is spread by mosquitoes and can infect animals and humans. The virus cannot be transmitted between humans, and it cannot be caught by eating pork or other pig products.
There is no specific treatment for JE, which can cause severe neurological illness with headache, convulsions and reduced consciousness in some cases.
The best thing people throughout the state can do to protect themselves and their families against JE is to take steps to avoid mosquito bites.
Simple actions you can take include:
