West Nile virus in Australia

Summary

West Nile Virus (WNV) is a mosquito borne virus belonging to the genus Flavivirus. A strain of WNV, Kunjin virus (WNVKUN) is endemic in parts of Australia and has been present for many years.

WNV is found across all continents except Antarctica. In Australia, WNVKUN has been infrequently associated with disease in humans. In 2011, there was a large outbreak of neurological disease in horses in South East Australia caused by a variant of the Australian strain WNVKUN.

West Nile virus infection has been confirmed in a horse from the Forbes district in February 2017.
