Twenty-two people are set to be released from hospital isolation following a hantavirus outbreak linked to the MV Hondius, marking a critical turning point in a medical crisis that has spanned three continents and some of the most remote corners of the Atlantic Ocean.
The release follows a period of intense monitoring and isolation for passengers and crew who were exposed to the virus during an expedition that began in South America. While the majority of those isolated are now cleared to return to their daily lives, the outbreak has left a trail of tragedy and a complex logistical puzzle for international health agencies.
Three people have died since the outbreak began. Among them were an elderly Dutch man and his wife, as well as a German woman. Health officials confirmed that two of the deceased tested positive for the virus, while the Dutch man passed away before a formal test could be administered.
A Global Map of Infection
The outbreak has created a fragmented medical emergency, with patients scattered across the globe. The UK Health Security Agency (UKHSA) is currently coordinating the care and repatriation of several British nationals who were onboard the vessel.
The dispersion of cases highlights the difficulty of containing a virus on an international expedition ship. Currently, two British nationals confirmed to have hantavirus are receiving treatment in the Netherlands and South Africa, respectively. Meanwhile, a British man remains in isolation on the remote island of Tristan da Cunha; officials report he is in stable condition, though his location—one of the most isolated inhabited places on Earth—complicates the delivery of specialized care.
Other passengers have already been moved. Two British nationals have returned to the United States via repatriation flights, and another is scheduled to return to Australia. In the United Kingdom, two additional Britons continue to voluntarily self-isolate at home. These individuals had disembarked the ship at St Helena on April 24, prior to the confirmation of the first hantavirus case.
From Ushuaia to the Canary Islands
The MV Hondius, operated by Oceanwide Expeditions, began its journey on April 1, departing from Ushuaia, Argentina. At the start of the voyage, the ship carried approximately 150 passengers and crew representing 28 different countries.
The crisis reached a head last week when the vessel docked in Spain’s Canary Islands. At that time, the ship had 87 passengers and 60 crew members on board. Following the confirmation of the outbreak, Oceanwide Expeditions initiated a mass repatriation effort to ensure all guests were returned to their home countries as quickly as possible.
The ship is now navigating back to the Netherlands. Onboard are 25 crew members and two medical professionals. In a sobering final detail, the vessel is also transporting the body of the German passenger who died during the outbreak.
| Patient Group | Status/Location | Nationality |
|---|---|---|
| Confirmed Cases | Under treatment (Netherlands, South Africa) | British |
| Suspected Case | Stable/Isolated (Tristan da Cunha) | British |
| Repatriated | Returned to US and Australia | British |
| Self-Isolating | Home isolation (United Kingdom) | British |
| Deceased | Two confirmed, one untested | Dutch, German |
WHO Monitoring and Containment
The World Health Organization (WHO) has been closely monitoring the situation to determine if the cluster represents a wider public health threat. Director-General Tedros Adhanom Ghebreyesus addressed the situation on Tuesday, offering a cautious but optimistic assessment.
“There is no sign that we are seeing the start of a larger outbreak,” Tedros said. However, he warned that the international community cannot yet relax its guard, adding that “work to contain it was not over as it’s possible we might see more cases.”
Hantaviruses are typically transmitted to humans through contact with the urine, feces, or saliva of infected rodents. Because they are not generally known to spread from person to person, the WHO’s focus remains on identifying the primary source of exposure on the vessel and ensuring that all exposed individuals are screened to prevent any unforeseen complications.

The next major milestone in the resolution of this crisis will be the arrival of the MV Hondius in the Netherlands, where the remaining crew and medical staff will undergo final health screenings and a full debrief of the ship’s logs will be conducted to pinpoint the origin of the virus.
