A British national is among four people to have died on a coronavirus-stricken cruise ship embroiled in a bitter dispute over plans to disembark passengers in the US.

In what is being described as an unfolding humanitarian crisis, so far two of the four people to have died on the cruise ship Zaandam have been confirmed to have had Covid-19, with nine people on board testing positive and 189 reporting flu-like symptoms.

Local authorities in Broward County, Florida – one of the locations the ship has been denied permission to dock – have urged the US Federal Government to step in.

“One of the deceased passengers is from the UK,” a spokesman for the Holland America cruise line, which operates the Zaandam, said in an email to the PA news agency.

“Due to US … laws, we cannot provide any additional medical and health details.”

The Zaandam, which is carrying more than 200 British nationals, and its sister ship the Rotterdam, passed through the Panama Canal on Monday after being denied entry to several ports. Both ships are seeking to dock in Florida later this week.

The state’s governor is reluctant to allow disembarkation for the more than 1,000 people on board the Zaandam, but US President Donald Trump appears set to overrule him.

Governor Ron DeSantis told a news conference on Tuesday that Florida’s healthcare resources were already stretched too thin by the coronavirus outbreak to take on the Zaandam’s caseload.

The US Coast Guard has said if local authorities cannot agree on a docking plan, the matter will go to the the federal government for decision.

Mr DeSantis said he had been in contact with the White House about ferrying medical supplies to the ships.

“Just to drop people off at the place where we’re having the highest number of cases right now just doesn’t make a whole lot of sense,” Mr DeSantis told a news conference.

However, Mr Trump said at the White House’s daily coronavirus briefing that he would ask Mr DeSantis to allow the ships to dock in Florida.

“They’re dying on the ship,” Mr Trump said. “I’m going to do what’s right. Not only for us, but for humanity.”

Holland America said 73 guests and 116 crew members on the Zaandam had reported influenza-like illness symptoms.

Covid-19 has been confirmed as causing two of the four deaths on the ship.

Nine people on the ship had tested positive to the coronavirus, Holland America said.

Company president Orlando Ashford wrote an opinion column in the South Florida Sun Sentinel newspaper to plead with officials and residents to let the passengers disembark.

“The Covid-19 situation is one of the most urgent tests of our common humanity,” he wrote. “To slam the door in the face of these people betrays our deepest human values.”

The Zaandam originally departed from Buenos Aires on March 7 — a day before the US State Department advised against cruise travel and before any substantial restrictions were in place in Florida.

The ship had been scheduled to stop in San Antonio, Chile, then complete another 20-day cruise to arrive in Fort Lauderdale, Florida, on April 7.

But since March 15, the Zaandam has assumed pariah-like status, having been denied entry at a succession of ports.

Michael Udine, commissioner of Broward County in Florida, one of the locations the Zaandam cruise ship has been denied permission to dock, has urged the US federal government to step in.

“Decisions with international implications should not be left to local officials to make piecemeal solutions during a global crisis,” Mr Udine said in a statement.

“Planning for a crisis such as this is something not to be done on the fly in multiple jurisdictions.

“Local officials do not have the resources or available options to them to take charge of international situations amid a global health crisis.

“We need experts from the CDC and Fema to do their jobs and outline a plan that takes the passengers out of limbo and does not play politics.”

Zaandam passengers said they were asked to keep their rooms dark and leave their curtains closed as they passed through the Panama Canal.

Holland America said that, after being denied entry to a number of ports, the Zaandam was forced to rendezvous with its sister ship and the Rotterdam took on nearly 1,400 people who appeared healthy. This left 450 guests and 602 crew members on the Zaandam.

The company said the two ships would remain together for the rest of the journey, and guests on both vessels would remain in their rooms until disembarkation.

Guy Jones, whose parents, Nick and Celia, are among some 229 British nationals on the luxury liner, said the cruise company had at least been keeping passengers informed.

He said that, although his parents, who are from Bristol, have an attitude of “keep calm and carry on”, they are still concerned about what the next step will be.

A Foreign Office spokesman said: “We are supporting the family of a British man who has died on board the Zaandam and are in touch with cruise ship operator. Our thoughts are with his family at this difficult time.

“We are doing all we can to help British people on board the Zaandam cruise ship.

“Our staff are in close contact with the cruise operator and the authorities in the region to ensure British people can get home safely.”
