The company said on Friday that four crew members “were isolated several days ago because of other disease symptoms, with no symptoms of Covid-19.
“There was no reason to suspect Covid-19 when the ship docked in Tromso based on the symptoms they were showing,” Hurtigruten said.
The ship had nearly 180 passengers on board since departing on July 25. None of the passengers reported symptoms related to coronavirus during the voyage, Hurtigruten said.
All passengers disembarked the ship on Friday but about 60 people have since been quarantined in Tromso, the cruise line said on Saturday. The crew members are the first coronavirus cases in Tromso hospital has seen since early June.
The cruise industry has been decimated by the pandemic after numerous high-profile outbreaks took place on ships of holidaymakers. The FCO currently advises against all ocean cruises.
The Norwegian Institute of Public Health has not ruled out the possibility of more cases emerging, “but we will only have the answer once the tests have been carried out”.
It recommended all passengers remain quarantined while awaiting their results.
As of Friday, Norway had 9,208 confirmed cases of coronavirus.
One person died of the virus on Friday night, bringing the country’s death toll to 256. It was the first coronavirus-related death in the Nordic country in two weeks.
