Monitoring continues for Japanese encephalitis – Update no. 8

5 April 2022

Agriculture Victoria is working closely with both the pig and horse industries in response to Japanese encephalitis.

Over the weekend there has been one new property with pigs confirmed with Japanese encephalitis in Victoria. There is now a total of 19 properties with pig cases across the Wangaratta, Moira, Greater Shepparton, Campaspe, Gannawarra, Loddon, Greater Bendigo and Northern Grampians local government areas. A number of suspected cases are under investigation.

These detections are 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 working 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. Only infected mosquitoes can spread infection. Pork is safe to eat.

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 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 mosquitoes.
