A scrub typhus outbreak occurred among 24 soldiers from 2 Australian Defence Force infantry units following separate training events conducted in the same coastal location in tropical North Queensland, Australia, in June 2022. Seven soldiers visited a hospital, 5 requiring admission. Outbreak recognition was hampered by the geographic dispersion of soldiers after the exercise and delayed case identification resulting from such factors as prolonged incubation, cross-reactive serologic responses to other pathogens, the nonspecific symptoms of scrub typhus, and the illness's nonnotifiable status in the state of Queensland. Our investigation focused on personal protective measures in a subanalysis of 41 soldiers, revealing an association between scrub typhus infection and the use of doxycycline chemoprophylaxis and permethrin uniform dipping.

2022 年澳大利亚沿海训练区士兵中的丛林斑疹伤寒爆发。


2022 年 6 月，在澳大利亚热带北昆士兰州的同一沿海地区进行了单独的训练活动后，来自 2 个澳大利亚国防军步兵部队的 24 名士兵爆发了丛林斑疹伤寒。7 名士兵去了一家医院，其中 5 人需要住院。演习后士兵的地理分散以及由于潜伏期延长、对其他病原体的交叉反应血清学反应、丛林斑疹伤寒的非特异性症状以及该疾病在昆士兰州的不可通报状态等因素导致病例识别延迟，阻碍了疫情识别。我们的调查集中在对 41 名士兵的亚分析中的个人防护措施，揭示了丛林斑疹伤寒感染与使用多西环素化学预防和氯菊酯均匀浸渍之间的关联。
