Kunjin virus (KUNV) is a zoonotic virus of the family Flaviviridae and the genus Flavivirus. It is a subtype of West Nile Virus endemic to Oceania.
The virus was first isolated from Culex annulirostris mosquitoes in Australia in 1960. The name of Kunjin virus derives from an Aboriginal clan living on the Mitchell River close to where the virus was first isolated in Kowanyama, northern Queensland.
Kunjin virus is a zoonotic virus of the family Flaviviridae and the genus Flavivirus. It is an arbovirus which is transmitted by mosquitoes and is part of the Japanese encephalitis serological complex. It is antigenically and genetically very similar to West Nile virus and in 1999 was reclassified as a subtype of WNV. Its genome is positive-sense single stranded RNA made up of 10,644 nucleotides.
Infection with the virus often causes no symptoms, but it can lead to either an encephalitic disease or a non-encephalitic disease. Non-encephalitic Kunjin virus disease can cause symptoms including acute febrile illness, headache, arthralgia, myalgia, fatigue and rash. Kunjin virus encephalitis features acute febrile meningoencephalitis.
