Carnival Corp’s Princess Cruises has been hit by yet another potential Covid-19 coronavirus outbreak on board one of its US-based cruiseships.

Two passengers on a previous cruise on the 107,500-gt Grand Princess (built 1998) tested positive for the virus after disembarking from the ship in San Francisco on 21 February.

One man, a 71-year-old California resident, has since died, prompting California governor Gavin Newsom to declare a state of emergency.
