Human-to-human transmission suspected on board hantavirus cruise ship, WHO says

Some human-to-human transmission may have occurred on board the cruise ship hit by a hantavirus outbreak that has left three people dead and several others ill, the World Health Organization (WHO) said Tuesday.

“We do know that some of the cases had very close contact with each other and certainly human-to-human transmission can’t be ruled out so as a precaution this is what we are assuming,” Dr. Maria Van Kerhove, WHO’s director for epidemic and pandemic preparedness and prevention, told reporters.

“The risk to the general public is low,” Van Kerkhove emphasized. “This is not a virus that spreads like flu or like COVID. It’s quite different.”

Almost 150 people, including 17 Americans, remain stranded on the MV Hondius that is currently off the coast of West Africa.

The ship, operated by tour company Oceanwide Expeditions, left Ushuaia, Argentina last month on a voyage across the Atlantic Ocean, stopping off at some of the world’s most remote islands. But along the way, several passengers fell sick with a rapidly progressing respiratory illness, the company said.

Seven cases of hantavirus, a rare disease typically caused by contact with infected rodents’ urine, faeces or saliva, have been identified so far. Two of those are confirmed and five suspected, WHO said Monday.

Three people – a Dutch couple and German national – have died while one British national remains in intensive care in South Africa, though Van Kerkhove said his condition is improving.

Two other people suffering from hantavirus symptoms remain on board the ship, though their medical evacuation is currently underway, Van Kerkhove said.

What happens next?

The top priority for health authorities is to evacuate the two symptomatic crew members so they can receive the medical care they require, Van Kerkhove said, adding that was underway Tuesday morning.

Such an evacuation involves two specialized, medically-equipped aircraft staffed by trained medical crews, the tour operator previously said Monday.

Once they have been evacuated, the plan is for the ship to sail to the Canary Islands where Spanish authorities will conduct a full epidemiological investigation and full disinfectation, Van Kerkhove said.

The Spanish health ministry has not decided the most appropriate port for the ship, it said in a statement to CNN which did not confirm if the ship is bound for the Canary Islands.

Strict health and safety procedures are currently in place on the ship, including isolation measures, hygiene protocols and medical monitoring. The company said the atmosphere “remains calm” and that passengers were “generally composed.”

One passenger, travel vlogger Jake Rosmarin, spoke of the fear and uncertainty percolating through the ship on Monday.

“What’s happening right now is very real for all of us here. We’re not just a story. We’re not just headlines,” he said in a video posted on Instagram, his voice cracking with emotion.

Beyond the ship itself, authorities have initiated contact tracing for those on the flight to Johannesburg with the Dutchwoman who later died.
