1/ #SARSCoV2 spread on #Boeing 777. Seven infections identified, at least 4 of which were likely the result of transmission events during 18 hr Dubai to New Zealand flight. Genomic sequencing confirmed virus genomes were identical/near identical

2/An alternative exposure event, such as in the Dubai Airport before takeoff, can't be definitely ruled out but a much more likely scenario is transmission in flight given the 7 were sitting in close proximity on the flight. The virus spread despite 5 of them reporting mask use.

3/Pre-flight testing did not catch the index case infection. Post-flight testing while in quarantine in New Zealand did, underscoring the importance of policy that requires quarantine for visitors.
