OBJECTIVE
To describe the first outbreak of Barmah Forest virus (BFv) in Tasmania and identify potential vectors for BFv in Tasmania.
METHODS
A retrospective descriptive study of BFv notifications in the Tasmanian Notifiable Diseases Database (TNDD) was conducted. Adult mosquitoes were sampled from areas near outbreak cases and pooled samples were tested for BFv.
RESULTS
27 cases of confirmed BFv were recorded in the TNDD between 12 March 1999 and 30 June 2019. Nine cases were recorded between 21 January and 10 May 2019 that were acquired in Tasmania, with eight included in this confirmed outbreak. All outbreak cases resided in or travelled to locations in the Break O'Day Local Government Area and reported no recent interstate travel. No virus was detected in pooled mosquito samples.
CONCLUSIONS
This is Tasmania's first confirmed outbreak of BFv. Known BFv vector species were identified in both saltmarsh and urban-fringe brackish saltmarsh larval habitats. BFv was not detected from pooled mosquito samples.
IMPLICATIONS FOR PUBLIC HEALTH
Clinicians should consider BFv as a possible diagnosis for presentations with fever and arthritis, and potential mosquito exposure in Tasmania. These findings will guide broadening of prevention-focussed public health messaging.
目的
描述塔斯马尼亚岛首次爆发的巴马森林病毒（BFv）疫情，并确定塔斯马尼亚岛BFv的潜在传播媒介。
方法
对塔斯马尼亚法定传染病数据库（TNDD）中BFv通报情况进行回顾性描述性研究。从疫情病例附近区域采集成年蚊子样本，对混合样本进行BFv检测。
结果
1999年3月12日至2019年6月30日期间，TNDD记录了27例确诊的BFv病例。2019年1月21日至5月10日期间记录了9例在塔斯马尼亚岛感染的病例，其中8例纳入本次确诊疫情。所有疫情病例均居住在或前往过布雷克奥代地方政府辖区内的地点，且报告近期无州际旅行史。在混合蚊子样本中未检测到病毒。
结论
这是塔斯马尼亚岛首次确诊的BFv疫情。在盐沼和城市边缘微咸盐沼幼虫栖息地均发现了已知的BFv传播媒介物种。在混合蚊子样本中未检测到BFv。
对公共卫生的启示
临床医生应将BFv视为塔斯马尼亚岛出现发热和关节炎症状且可能接触过蚊子的患者的一种可能诊断。这些发现将指导扩大以预防为重点的公共卫生宣传。
