A Kunjin virus (KUN) case with encephalitis
symptoms was reported from the Darwin area,
Northern Territory on 17 June 2010. The
diagnosis was confirmed on 5 August. Adult
mosquito trapping showed high vector mosquito
numbers at the time originating from large
swamps in the Howard Springs area. The
sentinel chicken program across the Top End
indicated probable KUN activity in the area, but no arboviruses were isolated from the
mosquitoes collected. With an incubation period for KUN of between 7 – 12 days and an onset date of 15 June, the patient most likely contracted the KUN around 5 June at his Howard Springs residence.
