Japanese Encephalitis in Victoria this summer

Date issued: 21 Jan 2025 – Update from 31 December 2024

Key messages 

  • A confirmed human case of Japanese encephalitis (JE) has been identified in a resident of northern Victoria, the first case of JE in Victoria this mosquito season. 
  • JE virus has also been detected through environmental surveillance in northern Victoria along the Murray River, and in mosquitoes and feral pigs in New South Wales this summer. 
  • These findings indicate that JE virus is likely circulating in northern Victoria this summer. 
  • JE virus can cause a rare but potentially serious infection of the brain and is spread to humans through bites from infected mosquitoes. 
  • Residents and people visiting northern Victoria, particularly inland riverine regions and near the Murray River, are potentially at higher risk of infection and should take measures to prevent mosquito bites. 
  • Avoid mosquito bites by using mosquito repellent containing picaridin or diethyltoluamide (DEET) on all exposed skin. Wear long, loose fitting clothing when outside, and ensure accommodation, including tents are properly fitted with mosquito nettings or screens. 
  • In Victoria, JE vaccine is available free-of-charge for specific groups at higher risk of exposure to the virus, including eligible people in 24 high-risk LGAs in northern Victoria. 
  • Clinicians should test for JE virus in patients with compatible illness and notify the Department of Health immediately of suspected cases by calling 1300 651 160 (24 hours).
