Health authorities worldwide are currently investigating a recent hantavirus outbreak linked to a cruise ship, prompting a global response to monitor potential contacts. In light of confirmed cases and fatalities, officials are striving to contain the situation and trace individuals who may have been exposed.
Hantavirus Outbreak Investigation
MADRID (AP) — Health authorities across four continents are actively tracking and monitoring passengers who disembarked the hantavirus-stricken cruise ship before the outbreak was detected, as they attempt to identify others who might have come into contact with them.
In Argentina, investigators are preparing to visit the southern town believed to be the outbreak’s origin, as per officials from the nation’s Health Ministry. They suspect that a Dutch couple may have contracted the virus during a bird-watching trip prior to boarding the cruise ship.
On April 24, nearly two weeks after the first passenger’s death on board, over two dozen individuals from at least 12 different countries left the ship without contact tracing, the vessel’s operator, along with Dutch officials, confirmed on Thursday.
Three passengers, including a Dutch couple and a German national, have succumbed to the outbreak, while several others are currently experiencing health issues. Symptoms typically appear between one and eight weeks following exposure.
Fortunately, none of the remaining passengers or crew members on the ship are exhibiting symptoms at this time, reported the Netherlands-based Oceanwide Expeditions cruise company.
The World Health Organization (WHO) has assessed the risk to the general public as low. Hantavirus generally spreads through inhalation of contaminated rodent droppings and is not easily passed between humans.
“We believe this will be a limited outbreak if public health measures are implemented and solidarity is shown across all countries,” stated Dr. Abdirahman Mahamud, WHO’s alert and response director.
1st hantavirus case on board was confirmed May 2
Health authorities confirmed the first hantavirus case on the ship on May 2, after a British man evacuated to South Africa tested positive. He is currently receiving intensive care there.
Three individuals, including the ship’s doctor, were evacuated on Wednesday while near Cape Verde and were taken to specialized hospitals in Europe for treatment.
The remains of the Dutch man, who was the first fatality on board on April 11, were removed from the ship at St. Helena on April 24, along with his wife. She subsequently traveled to South Africa the following day, where she also passed away.
The ship’s operator reported 30 passengers, including the deceased husband and wife, disembarked at St. Helena. The Dutch Foreign Ministry indicated the figure was around 40, highlighting that many more passengers left the ship on April 24 than previously acknowledged.
Passengers who disembarked April 24 are being monitored
Authorities reported that a man in Switzerland tested positive for hantavirus after leaving the ship in St. Helena, though his movements in the intervening period remain unclear.
On Thursday, health officials in Singapore stated they were monitoring two men who left the ship at St. Helena, traveled to South Africa, and then returned home. They were being isolated and tested.
Additionally, authorities in St. Helena are monitoring a few individuals categorized as “higher risk contacts.” These individuals are being instructed to isolate for 45 days, according to the St. Helena government.
South Africa is tracing contacts from an April 25 flight
The Dutch health ministry announced on Thursday that a flight attendant on a plane briefly boarded by an infected cruise passenger in South Africa is displaying symptoms of hantavirus and will be tested in an isolation ward at an Amsterdam hospital. The cruise passenger, the Dutch woman whose husband died on the ship, was too ill to continue on the international flight to Europe and was taken off the plane in Johannesburg, where she later passed away.
If the flight attendant tests positive, she would be the first known case not present on the MV Hondius to contract the virus during this outbreak.
The vessel is currently headed to the Canary Islands, with an estimated arrival date of Saturday or Sunday, and more than 140 passengers and crew members still onboard.
WHO Director-General Tedros Adhanom Ghebreyesus mentioned on Thursday that he has kept in regular contact with the ship’s captain, stating that morale improved once the ship resumed its course.
Authorities in South Africa are also tracing contacts of any passengers who previously disembarked the ship. They have particularly focused on an April 25 flight from St. Helena to Johannesburg, which took place the day after passengers disembarked there.
A French citizen with “benign symptoms” is currently in isolation while undergoing medical tests after being identified as a contact case linked to the cruise passenger from the St. Helena to Johannesburg flight confirmed to have hantavirus, as reported by the French Health Ministry on Thursday.
The Dutch woman who later died in South Africa was also on the St. Helena-Johannesburg flight. It remains unclear how many other cruise passengers were among the 88 individuals on board, but flights from St. Helena are infrequent, typically occurring once a week.
The remains of the third fatality, a German woman, also remain on the ship after she passed away on May 2.
Unlike other hantaviruses, Andes virus may spread between people
Confirmatory tests have identified at least five individuals aboard the ship who are infected with the Andes virus, a form of hantavirus specific to South America. It is the only known hantavirus to transmit between humans, potentially causing severe pulmonary ailments.
The ship departed from Argentina, where inquiries regarding the outbreak’s origin are focusing. The Dutch couple associated with the first two confirmed cases traveled through Argentina, Chile, and Uruguay prior to boarding the ship, visiting locations known to harbor the rodents that carry the Andes virus.
Argentina’s Health Ministry is particularly investigating the town of Ushuaia; however, the investigative team has not yet been deployed, according to their public statement. Experts from the state-supported Malbrán Institute are expected to travel to Ushuaia within the coming days to analyze local rodents for the virus.
The WHO is collaborating with Argentine health authorities to trace the couple’s travels and has arranged for 2,500 diagnostic kits to be sent from Argentina to labs in five different countries.
Argentina’s health ministry recently reported 28 deaths from hantavirus last year, marking a significant increase from the average of 15 fatalities per year over the past five years, noting that approximately a third of cases during that period were deadly.

FAQ
What is hantavirus?
Hantavirus refers to a group of viruses primarily spread by rodents and can cause severe respiratory issues in humans.
How is the Andes virus different from other hantaviruses?
The Andes virus is unique as it is the only hantavirus known to transmit between people, unlike other strains that primarily spread through rodent droppings.
What precautions are authorities taking?
Health officials are monitoring passengers who disembarked the affected cruise ship and conducting contact tracing efforts globally.
In summary, the ongoing hantavirus outbreak linked to the MV Hondius cruise ship has prompted worldwide health agencies to implement contact tracing and monitoring measures. Collaborative efforts are focused on investigating the outbreak’s origins while ensuring public health safety.
