Health Officials Monitor Passengers After Hantavirus Death on Ship

As health officials around the globe respond to a hantavirus outbreak linked to the MV Hondius cruise ship, the situation highlights the importance of effective monitoring and contact tracing. With continued investigations into the origins and spread of the virus, vigilance remains crucial for passenger safety and public health.

MADRID — Health authorities across four continents were engaged in tracking and monitoring passengers who disembarked from a hantavirus-affected cruise ship before a deadly outbreak was identified. They are also attempting to trace anyone who may have had contact with them since then.

In Argentina, investigators are preparing to depart for the southern town believed to be the outbreak’s origin, according to representatives from the country’s Health Ministry. They suspect that a Dutch couple contracted the virus during a bird-watching expedition prior to boarding the cruise.

On April 24, nearly two weeks after the initial passenger’s death onboard, over two dozen individuals from at least 12 countries departed the ship with no contact tracing performed, reported the ship’s operator and Dutch officials on Thursday.

The outbreak has claimed the lives of three passengers, including a Dutch couple and a German national. Several others are exhibiting symptoms, which typically develop within one to eight weeks following exposure.

As of Thursday, none of the remaining passengers or crew are showing any symptoms, stated the Netherlands-based Oceanwide Expeditions, the cruise ship operator.

The World Health Organization (WHO) has indicated that the overall risk to the public remains low. Hantavirus is generally transmitted through inhalation of contaminated rodent droppings and is not easily spread between humans.

Dr. Abdirahman Mahamud, the WHO’s director for alert and response, expressed optimism, stating, “We believe this will be a limited outbreak if public health measures are adhered to and international cooperation is maintained.”

1st hantavirus case on board was confirmed May 2

On Wednesday, three individuals, including the ship’s doctor, were evacuated while the ship was near Cape Verde and transported to specialized hospitals in Europe for treatment.

The body of the Dutch man who was the first to die onboard on April 11 was removed from the ship at St. Helena on April 24, after which his wife disembarked and later died in South Africa.

The ship’s operator announced that 30 passengers, including the deceased Dutch man and his wife, disembarked at St. Helena. The Dutch Foreign Ministry estimated the figure to be around 40. Previously, the operator had not disclosed that many more people left the ship on April 24.

The first confirmed hantavirus case among ship passengers was detected on May 2, when a British man was evacuated to South Africa three days after the St. Helena stop. He is currently in intensive care.

Passengers who disembarked April 24 are being monitored

Recent reports revealed that a man tested positive for hantavirus in Switzerland after leaving the ship at St. Helena, though the specifics of his movements are unclear.

Health authorities in Singapore are currently monitoring two men who exited the ship at St. Helena, traveled to South Africa, and then returned home. They are being isolated and tested.

Authorities in St. Helena are observing a small group classified as “higher risk contacts,” advising them to isolate for a period of 45 days, according to the local government.

South Africa is tracing contacts from an April 25 flight

The Dutch health ministry reported that a flight attendant on a plane briefly boarded by an infected cruise passenger is exhibiting symptoms and will be tested in an isolation ward in an Amsterdam hospital. The cruise passenger, who lost her husband aboard the ship, was too ill to continue on an international flight and passed away in Johannesburg.

If the Dutch flight attendant tests positive, she could potentially be the first confirmed case outside the MV Hondius amidst this outbreak.

The vessel is currently en route to Spain’s Canary Islands, with an expected arrival this weekend, carrying over 140 passengers and crew members still aboard.

WHO Director-General Tedros Adhanom Ghebreyesus noted that he had ongoing communication with the ship’s captain, reporting improved morale as the vessel continued its journey.

South African authorities are actively tracing contacts of passengers who previously disembarked the ship, concentrating their efforts on an April 25 flight from St. Helena to Johannesburg, the day following passenger disembarkation.

A French citizen exhibiting “benign symptoms” is in isolation and undergoing medical assessments, linked to the cruise passenger confirmed with hantavirus on the April 25 flight from St. Helena to Johannesburg.

Institutions have confirmed that another passenger, who passed away in South Africa after leaving the cruise, had been on the same flight.

The body of the third deceased, a German woman, remains onboard following her death on May 2.

Unlike other hantaviruses, Andes virus may spread between people

Confirmed tests show that at least five individuals from the ship are infected with Andes virus, a type of hantavirus found in South America. This strain is the only known hantavirus transmitted between humans and can lead to a severe, often fatal respiratory disease.

The ship’s itinerary included stops in Argentina, where investigations are focusing on the outbreak’s source.

The Dutch couple presenting the first two cases traveled through Argentina, Chile, and Uruguay before boarding the vessel, visiting regions known for the Andean rat species that transmit the virus.

Argentina’s Health Ministry is currently focusing on Ushuaia for their investigation but has yet to deploy a team, as stated in their official communication. Experts from the state-funded Malbrán Institute are slated to visit Ushuaia shortly.

Once there, a flight from Argentina’s capital, Buenos Aires, they will analyze rodents at local refuse sites to assess if they carry the Andes virus.

The WHO is collaborating with Argentinian health authorities to track the couple’s movements and has organized the shipment of 2,500 diagnostic kits to laboratories across five countries.

According to the Argentinian health ministry, there were 28 hantavirus-related deaths last year, a marked increase from an average of 15 fatalities during the preceding five years. Nearly a third of last year’s cases resulted in death.
