Mosquito Warning Issued After Japanese Encephalitis Detection in Southern NSW
13 Jan 2026
A man in his 60s is being assessed after likely exposure to JE in the Riverina region in late December. The alert follows confirmation that JE virus was also detected in sentinel chickens near Goulburn in early January 2026, indicating local mosquito activity carrying the virus.
Japanese encephalitis is a rare but potentially serious disease spread by infected mosquitoes. While many cases are mild, severe illness can cause brain inflammation, leading to confusion, seizures and reduced consciousness.
Health authorities are urging people who live, work or travel in high-risk areas to avoid mosquito bites and consider vaccination, noting there is no specific treatment for JE.
A free vaccine is available for eligible people through GPs, Aboriginal health services and pharmacies. Some individuals may require a booster dose and should seek advice from a healthcare provider.
Residents are advised to reduce mosquito exposure by using repellents, wearing protective clothing, avoiding outdoor activity at dawn and dusk, removing standing water around homes and ensuring doors and windows are properly screened.
NSW Health confirmed the virus cannot spread directly between people.
