In August 2021, there was an outbreak of severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) Delta variant on an international liquified natural gas (LNG) vessel offshore to Gladstone, Queensland. Fourteen of the 26 crew members aboard the vessel tested positive for SARS-COV-2 on PCR during the outbreak. Vaccine effectiveness (VE) was 52% for all lab-confirmed SARS-CoV-2 infections, 65% for symptomatic SARS-CoV-2 infection and 100% for severe SARS-CoV-2. The attack rate (AR) of SARS-CoV-2 Delta variant was 54% (14/26). With heightened public health measures and infection control practices, we were able to declare the outbreak over in 26 days.
2021 年 8 月，在昆士兰州格拉德斯通近海的一艘国际液化天然气（LNG）船上爆发了严重急性呼吸综合征冠状病毒 2 型（SARS-CoV-2）Delta 变体。在疫情爆发期间，船上的 26 名船员中有 14 人经 PCR 检测对 SARS-CoV-2 呈阳性。疫苗有效性（VE）对所有实验室确诊的 SARS-CoV-2 感染为 52%，对有症状的 SARS-CoV-2 感染为 65%，对严重的 SARS-CoV-2 感染为 100%。SARS-CoV-2 Delta 变体的发病率（AR）为 54%（14/26）。通过加强公共卫生措施和感染控制措施，我们能够在 26 天内宣布疫情结束。
