摘要：Detection of flavivirus seroconversions in sentinel chicken flocks located throughout Australia is used toprovide an early warning of increased levels of Murray Valley encephalitis (MVE) and Kunjin virus activityin the region. During the 2001/2002 season low levels of flavivirus activity were detected in northernAustralia compared to previous years. MVE and Kunjin virus activity was detected in the Kimberley andPilbara regions of Western Australia and the Northern Territory but not in north Queensland, New SouthWales or Victoria. This is in contrast to the previous season when MVE activity was detected both innorthern Australia and, for the first time in over 20 years, in New South Wales. Two cases of Murray Valleyencephalitis were reported from the north of Western Australia during the 2001/2002 wet season
