SARS-CoV-2 Testing Prior to International Airline Travel, December 2020-May 2021   [open pdf - 0B]

From the Abstract: "While there have been several case reports and simulation models of SARS-CoV-2 [severe acute respiratory syndrome coronavirus 2] transmission associated with air travel, there are limited data to guide testing strategy to minimize the risk of SARS-CoV-2 exposure and transmission onboard commercial aircraft. Among 9,853 passengers with a negative SARS-CoV-2 PCR [polymerase chain reaction] performed within 72 hours of departure from December 2020 through May 2021, five (0.05%) passengers with active SARS-CoV-2 infection were identified with rapid antigen tests and confirmed with rapid molecular test performed before and after an international flight from the United States to Italy. This translates to a case detection rate of one per 1970 travelers during a time of high prevalence of active infection in the United States. A negative molecular test for SARS-CoV-2 within 72 hours of international airline departure results in a low probability of active infection identified on antigen testing during commercial airline flight."
