 Specimen yielded lineage not circulating in place of origin
AND
Lineage closely matched that of passengers with primary cases on flight

 Passenger on cruise ship with no known SARS-CoV-2 transmission identified Specimen from passenger or traveling companion yielded lineage related to that of passengers with primary cases on flight
Domestic passenger in Australia not associated with a cruise ship before illness
