In an alarming development, health authorities in Victoria, Australia have detected the potentially deadly Japanese encephalitis virus in a resident of the state’s north. The Department of Health issued an urgent alert on Tuesday, marking the likely first summer case of this dangerous mosquito-borne disease. With the virus also identified in mosquitoes and feral pigs in neighboring New South Wales, officials are warning that the risk of infection is expected to remain high in the coming weeks.
Understanding the Japanese Encephalitis Threat
Japanese encephalitis, a flavivirus closely related to dengue and yellow fever, is primarily transmitted through the bites of infected mosquitoes. While most people who contract the virus do not develop symptoms, in rare cases it can lead to severe complications affecting the brain:
- Mild symptoms may include fever, headache, and vomiting
- In serious cases, patients can experience seizures, paralysis, and even death
- Children under 5 and seniors are at higher risk for severe illness
Virus Detected in Victoria and New South Wales
The Japanese encephalitis virus was picked up by environmental surveillance in northern Victoria along the Murray River, a known hotspot for mosquito activity. In addition, the virus has been found in mosquitoes and feral pigs across the border in New South Wales. With over 50 local government areas in NSW already identified as being at elevated risk, health experts are deeply concerned about the potential for the disease to spread.
“The risk of mosquito-borne diseases remains high in the coming weeks. Taking measures is critical to protect against infections.”

Urgent Call for Mosquito Prevention Measures
As the warm, wet weather creates ideal breeding conditions for mosquitoes, health officials are imploring residents and visitors in high-risk areas to take extra precautions:
- Use insect repellent on all exposed skin when outdoors
- Wear long, loose-fitting clothing to minimize skin exposure
- Ensure accommodations have proper mosquito netting or screens
- Remove any standing water around homes and campsites
Mosquito surveillance and testing will continue throughout the summer to help identify areas of greatest concern. However, with the peak virus transmission season extending from November to March, the threat is expected to persist for quite some time.
Vigilance Key to Preventing Japanese Encephalitis
While Japanese encephalitis remains a rare disease in Australia, the potential for severe outcomes, including permanent neurological damage and death, demands that we take this threat with the utmost seriousness. By understanding the risks, taking sensible precautions, and heeding the guidance of health authorities, we can all play a part in limiting the spread of this dangerous virus.
Stay informed, stay protected, and if you suspect any signs of infection, seek medical attention without delay. Together, we can navigate this latest health challenge and emerge stronger and more resilient than ever.
