Monitoring continues for Japanese encephalitis - Update no. 6

24 March 2022

Agriculture Victoria has detected Japanese encephalitis virus at one new piggery.

The detection is the result of national surveillance efforts to identify new cases and determine the extent and spread of the disease and the source of its introduction.

Japanese encephalitis has also been confirmed in piggeries in New South Wales, Queensland and South Australia.

Agriculture Victoria is also working closely with both the pig and horse industries in response to the disease. A number of suspected cases are under investigation.

Detections have been confirmed at a total of 15 properties in the Wangaratta, Moira, Greater Shepparton, Campaspe, Gannawarra, Loddon, Greater Bendigo and Northern Grampians local government areas.

Agriculture Victoria’s incident management team continues to work closely with industry, conducting surveillance activities and providing advice and information to farmers, livestock and horse owners.

Infection is not spread directly from pigs to people, and there is no risk to humans from eating pig meat.

In general, spread is through the movement of migratory water birds and through the movement of infected mosquitoes, often over long distances. It does not usually spread directly from animal to animal (i.e. it is not considered contagious).

Victorians are being reminded to protect themselves from mosquito bites particularly when we are spending time outdoors.

Japanese Encephalitis vaccines are recommended for people at a higher risk of exposure to the virus, such as those working with pigs. All people should undertake measures to reduce exposure to mosquitos.
