Authorities have not released details about the person’s condition.

Recent weather conditions have been favourable for mosquito breeding and biting, and mosquito numbers are high across many parts of Victoria.

The Victorian Department of Health said on December 30 there was ongoing concern about JE virus transmission in riverine regions, which had been hit hard by flooding during recent months in towns including Echuca and Rochester and along the Murray River.

The virus is spread by mosquitoes and most people will experience no symptoms, but about one per cent of cases will become severely unwell.

Symptoms can include confusion, headaches, vomiting, seizures and disorientation, and may lead to neurological damage or death.

Anyone experiencing these symptoms should seek urgent medical attention.

The Department of Health said people who spent time working or camping outdoors in inland riverine areas or near the Murray River were at increased risk of exposure.

Vaccine supply is limited in Australia, but it is free for Victorians in flood-affected areas.
