Hundreds more passengers who travelled on the MS Roald Amundsen are in quarantine and awaiting test results, the company that owns the ship said.
The ship, which belongs to the Norwegian firm Hurtigruten, docked in the port of Tromso in northern Norway on Friday.
Hurtigruten has halted all leisure cruises because of the outbreak.
"This is a serious situation for everyone involved. We have not been good enough and we have made mistakes," Chief Executive Daniel Skjeldamsaid in a statement on Monday.
