The BBC reports that most of those on board are British, and that Fred Olsen Cruise Lines said it was "undertaking extensive sanitisation measures and cleaning of the ship".
The Balmoral left Southampton on 16 April for a 34-night 'Old England to New England' cruise. The ship has capacity for 1,350 passengers, and is the largest and newest ship in the cruise line's fleet, according to Reuters.
It was docked in Portland, Maine, on Sunday, and is expected to arrive in Saint John, in the Canadian province of New Brunswick, on Monday.
The Mirror reports that a company statement added: "Fred Olsen has been undertaking extensive sanitisation measures and cleaning of the ship, in accordance with its strict illness containment and prevention plan.
"Fred Olsen is co-operating fully with all the necessary maritime agencies and authorities, as Balmoral continues on her cruise, and will continue to make every effort possible to ensure the safety and wellbeing of all its guests and crew on board, which is of paramount importance."
