A flu outbreak affected 82 passengers and crew on an RCI-Royal Caribbean ship that returned from the Caribbean to Baltimore MD last week.
The accident prompted RCI to quarantine the infected and notify CDC (US Centers for Disease Control). None of the sick met the criteria for Coronavirus (COVID-19), a spokeswoman for RCI has confirmed. Also, none of them had transited any Coronavirus-impacted regions within the last 14 days.
According to RCI, an elevated number of passengers and crew had "flu-like illness or tested positive for influenza A or B and were placed in isolation, according to medical protocol." The CDC didn't request Coronavirus tests for any of the cases.
At the time of the accident, Grandeur of the Seas was en-route from homeport Baltimore to Puerto Rico, St Maarten, St Lucia, Barbados, St Kitts.
Amid the coronavirus concerns, passengers leaving from Baltimore are being screened prior to boarding the cruise ships. Anyone who has visited areas affected by the deadly disease or who has come into contact with others who have been to those areas during the past 2 weeks will not be allowed to board.
