Develop and evaluate a pre-deployment sequestration (PDS) protocol to prevent SARS-CoV-2 cases on board the USS RONALD REAGAN (CVN-76).
The USS RONALD REAGAN includes a crew of approximately 3,000 Sailors and an embarked Air Wing of 2,000 personnel. The PDS was conducted in three waves of 14-day strict quarantines during the months of April and May 2020. Sailors were cleared to board the ship with two negative rtPCR tests at days 14 and 16. The ship was sanitized prior to Wave 1 boarding.
From March 1, 2020 through May 31, 2020, a total of 51 SARS-CoV-2 positive cases were detected. During the three waves of PDS, 28 Sailors were found to be positive on exit testing (14, 11, and 3, respectively); no cases were found among the Air Wing. During the first 90 days at sea, no SARS-CoV-2 cases were detected among any of the embarked personnel.
Although resource-intensive, the PDS protocol implemented for USS RONALD REAGAN resulted in a COVID-free ship during a global pandemic with unprecedented scope. Elements of this pandemic PDS protocol may be useful in other highly risk-averse environments with no tolerance for COVID-19 infections.
制定并评估一项部署前隔离（PDS）方案，以防止“罗纳德·里根”号航空母舰（CVN - 76）上出现新冠病毒感染病例。
“罗纳德·里根”号航空母舰搭载约3000名船员和一支由2000名人员组成的舰载机联队。2020年4月和5月期间，PDS分三个阶段进行，每次为期14天的严格隔离。船员在第14天和第16天的两次逆转录聚合酶链反应（rtPCR）检测呈阴性后被批准登船。在第一阶段登船前，对舰艇进行了消毒。
从2020年3月1日至2020年5月31日，共检测到51例新冠病毒阳性病例。在PDS的三个阶段中，分别有28名船员在离船检测时呈阳性（分别为14例、11例和3例）；舰载机联队中未发现病例。在海上航行的前90天里，所有登船人员中均未检测到新冠病毒感染病例。
尽管资源密集，但为“罗纳德·里根”号实施的PDS方案在全球范围内前所未有的大流行期间使舰艇实现了无新冠病毒感染。这种大流行期间的PDS方案的要素可能对其他对新冠病毒感染零容忍的高风险规避环境有用。
