Possible cases of Japanese encephalitis virus (JEV) have led to warnings for Victorians to protect themselves against mosquito bites.
The Victorian government said evidence of the virus has been found in pigs in Echuca as well as near the New South Wales border and in southern Queensland.
JEV is a mosquito-borne virus that can develop into encephalitis, an inflammation of the brain, which can be life-threatening.
“Most people with JEV will have no or very mild symptoms, but anyone who develops a sudden onset of fever, headache and vomiting should see their doctor immediately,” Chief Health Officer Professor Brett Sutton said.
“People with these symptoms can deteriorate over just a few short days, including suffering a loss of coordination, disorientation, generalised weakness and in some cases issues with movement which can last for years.”
Professor Sutton said the disease can’t spread between humans and simple steps can be taken to prevent mosquito bites.
“We can all protect ourselves by avoiding mosquito bites, including covering up, wearing loose fitting clothing and using mosquito repellants.”
While there are no confirmed human cases of the JEV strain in Victoria, several cases of encephalitis have been identified.
People with increased exposure to mosquitoes could be at higher risk of infection, particularly those in contact with pigs, people camping, working or spending time outdoors and people in regional areas.
Older people and children aged under five-years-old who are infected with JEV have a higher risk of developing a more severe illness.
