Following the first reported outbreak of fatal encephalitis on Badu Island in 1995, Japanese encephalitis virus (JEV) activity has occurred annually in the Torres Strait islands of northern Australia. There have been four recognised human cases, resulting in two deaths, as well as widespread human and porcine infection on many other islands (Hanna et a1. 1996, Hanna et a1. 1999). JEV activity has also been recognised on the Australian mainland, with a single human case in a fisherman at mouth of the Mitchell river in 1998, and detections in sentinel and domestic pigs on Cape York Peninsula in 1998 and 2004 (Hanna et a1. 1999). Virus isolation studies, vector competence experiments and analysis of host feeding patterns have incriminated Culex annu/irostris Skuse as the primary Australian JEV vector, occupying a similar niche to ex. tritaeniorhynchus Giles in Southeast Asia (Ritchie et a1. 1997, Johansen et al. 2001, van den Hurk et a1. 2003a, van den Hurk et al. 2003b). Other species that may playa secondary role in JEV transmission include Cx. gelidus Theobald, Cx. sitiens Wiedemann, Cx. quinquefasciatus Say and Ochlerotatus vigilax (Skuse) (Johansen et a1. 2001, van den Hurk et al. 2001b, van den Hurk et al. 2003b).
