NSW health authorities issue Japanese Encephalitis warning

Health authorities in New South Wales are warning residents in high-risk regional areas to protect themselves against the Japanese Encephalitis Virus (JEV) as warmer weather approaches. The virus is spread to humans via mosquito bites after the insects feed on infected pigs or waterbirds.

High-risk zones include Dubbo, Gilgandra, Narromine, Warren, Forbes, Orange, and Parkes. While many infections are asymptomatic, some individuals may experience fever, headache, and vomiting. In rare instances, approximately 1 in 250 cases, the infection can become severe, leading to neck stiffness, disorientation, seizures, or paralysis.

Individuals living or working near piggeries, or those frequently active outdoors in these regions, are at higher risk. NSW Health is offering a free JEV vaccine to people aged over two months who reside in, work in, or are traveling to high-risk Local Government Areas for outdoor recreation. The vaccine program is available until January 31, 2027.
