The Victorian Department of Health recommends people limit their exposure to mosquitoes following the death of a northern Victorian man from the rare Japanese Encephalitis virus (JEV) on February 28.
It is the first recorded death from JEV in the state, which is mosquito-borne and causes approximately one per cent of cases who become infected to contract encephalitis.
The department said that in most cases, the virus is mild, with no or very mild symptoms, but if a person develops a sudden fever, a headache, vomiting, disorientation or seizures, they should seek urgent medical assistance.
It is understood investigations are ongoing into how the man contracted the virus.
A Department of Health spokesperson said the man was in his 60s.
“Our thoughts are with his family and friends at this incredibly difficult time,” the spokesperson said.
“We strongly advise people take steps to limit their exposure to mosquitoes and avoid mosquito habitats such as stagnant water.”
The department said as of Tuesday, March 8, there had been seven confirmed cases of JEV in Victoria.
A vaccine is available and is recommended for anyone who comes into contact with pigs, such as transport workers, vets, hunters or cullers, the department said.
Children aged under five as well as older people who become infected with JEV are at higher risk of developing encephalitis, they added.
With mosquito numbers high in parts of northern Victoria, people with increased exposure to them may be at higher risk of infection – especially people who spend time around pigs, work or spend time outdoors, the department said.
