Many health departments and private enterprises began offering SARS-CoV-2 testing to travelers at US airports in 2020. Persons with positive SARS-CoV-2 test results who have planned upcoming travel may be subject to US federal public health travel restrictions. We assessed availability of testing for SARS-CoV-2 at major US airports. We then describe the management of cases and close contacts at Denver International Airport's testing site.
We selected 100 US airports. Online surveys were conducted during November-December 2020 and assessed availability of testing for air travelers, flight crew, and airport employees. Respondents included health department (HD) staff or airport directors. We analyzed testing data and management practices for persons who tested positive and their close contacts at one airport (Denver International) from 12/21/2020 to 3/31/2021.
Among the 100 selected airports, we received information on 77 airports; 38 (49%) had a testing site and several more planned to offer one (N = 7; 9%). Most sites began testing in the fall of 2020. The most frequently offered tests were RT-PCR or other NAAT tests (N = 28). Denver International Airport offered voluntary SARS-CoV-2 testing. Fifty-four people had positive results among 5724 tests conducted from 12/21/2020 to 3/31/2021 for a total positivity of < 1%. Of these, 15 were travelers with imminent flights. The Denver HD issued an order requiring the testing site to immediately report cases and notify airlines to cancel upcoming flight itineraries for infected travelers and their traveling close contacts, minimizing the use of federal travel restrictions.
As of December 2020, nearly half of surveyed US airports had SARS-CoV-2 testing sites. Such large-scale adoption of airport testing for a communicable disease is unprecedented and presents new challenges for travelers, airlines, airports, and public health authorities. This assessment was completed before the US and other countries began enforcing entry testing requirements; testing at airports will likely increase as travel demand returns and test requirements for travel evolve. Lessons from Denver demonstrate how HDs can play a key role in engaging airport testing sites to ensure people who test positive for SARS-CoV-2 immediately before travel do not travel on commercial aircraft.
2020年，许多卫生部门和民营企业开始在美国机场为旅行者提供新冠病毒检测。新冠病毒检测结果呈阳性且计划近期出行的人可能会受到美国联邦公共卫生旅行限制。我们评估了美国主要机场的新冠病毒检测服务可及性。然后，我们描述了丹佛国际机场检测点对病例及密切接触者的管理情况。
我们选取了100个美国机场。在2020年11月至12月期间开展了在线调查，评估了为航空旅客、机组人员和机场员工提供检测服务的可及性。受访者包括卫生部门工作人员或机场主管。我们分析了2020年12月21日至2021年3月31日期间在一个机场（丹佛国际机场）检测呈阳性的人员及其密切接触者的检测数据和管理措施。
在选取的100个机场中，我们收到了77个机场的信息；其中38个（49%）设有检测点，还有几个计划设立检测点（7个，9%）。大多数检测点于2020年秋季开始提供检测服务。最常提供的检测是逆转录聚合酶链反应（RT-PCR）检测或其他核酸扩增检测（NAAT）（28个）。丹佛国际机场提供新冠病毒自愿检测服务。在2020年12月21日至2021年3月31日期间进行的5724次检测中，有54人检测结果呈阳性，总体阳性率<1%。其中，15人是即将搭乘航班的旅行者。丹佛卫生部门发布命令，要求检测点立即报告病例，并通知航空公司取消受感染旅行者及其随行密切接触者的近期航班行程，尽量减少联邦旅行限制措施的使用。
截至2020年12月，近一半接受调查的美国机场设有新冠病毒检测点。如此大规模地在机场开展传染病检测是前所未有的，给旅行者、航空公司、机场和公共卫生当局带来了新挑战。这项评估是在美国和其他国家开始实施入境检测要求之前完成的；随着旅行需求回升以及旅行检测要求的演变，机场检测可能会增加。丹佛国际机场的经验表明，卫生部门在促使机场检测点发挥作用方面可起到关键作用，以确保在旅行前新冠病毒检测呈阳性的人员不会搭乘商业航班出行。
