Japanese encephalitis virus (JEV) is transmitted to humans and other animals by the bite of infected mosquitoes. A number of pig properties have recently been identified with JE virus infection. Pigs are important in JEV transmission because pigs develop high levels of viremia sufficient to infect mosquitoes (amplifying host).
There are two safe and effective vaccines for JE:
NSW Health has expanded access to JE vaccine - refer to Information on people recommended to be vaccinated against Japanese encephalitis.
