Victoria has confirmed its first likely summer case of Japanese encephalitis, a mosquito-borne virus that can cause severe illness and death.
The Department of Health announced the case on Tuesday, identifying the patient as a resident in northern Victoria. The virus has also been detected in environmental surveillance along the Murray River and in mosquitoes and feral pigs in New South Wales.
Symptoms can include fever, vomiting, and headaches, with severe cases leading to seizures, paralysis, or permanent disability.
Dr. Christian McGrath, Victoria’s Acting Chief Health Officer, urged residents in affected regions to use insect repellents, wear protective clothing, and ensure accommodations are mosquito-proof. “The risk of mosquito-borne diseases remains high in the coming weeks,” McGrath said.
The alert follows similar concerns in Queensland after heavy rains increased mosquito populations, heightening the risk of spread. Surveillance efforts continue to pinpoint high-risk areas.
