The 2026 hantavirus outbreak linked to the cruise ship MV Hondius unfolded over six weeks, evolving from an undetected death at sea to a 22-country international evacuation. This article documents the MV Hondius hantavirus timeline in full — every key event, every confirmed death, and every significant response milestone, from the ship's departure in Argentina to its final docking in Tenerife, Spain.
Background: The MV Hondius Cruise Ship
The MV Hondius is owned and operated by the Dutch company Oceanwide Expeditions, which specializes in high-end polar and remote-island expedition cruises. The vessel has accommodation for up to 196 passengers across 95 cabins, with a crew complement of 72. The ship is named after Dutch explorer Jodocus Hondius and is certified for operations in remote and ice-adjacent waters.
Owner: Oceanwide Expeditions (Netherlands)
Capacity: 196 passengers, 95 cabins
Crew: 72
Departure point: Ushuaia, Argentina
Passengers on departure: 175 (23 nationalities)
Berth prices: €14,000 – €22,000
Passengers on the voyage were predominantly from Spain, France, the United Kingdom, and the United States; the majority of crew were from the Philippines. The cruise was planned as an expedition to Antarctica and several remote South Atlantic islands. None of the passengers could have anticipated that the voyage would become the centerpiece of a global public health crisis.
April 2026: The Outbreak Begins
April 1, 2026
MV Hondius departs Ushuaia, Argentina
The ship departs with 175 passengers and crew representing 23 nationalities. The voyage is bound for Antarctica and isolated South Atlantic islands. The index case — a 70-year-old Dutch passenger — is believed to have been in the late incubation phase of Andes virus infection, having traveled through rodent-endemic regions of South America in the preceding four months.
April 6, 2026
First patient begins showing symptoms
The 70-year-old Dutch male passenger develops the first symptoms: fever, severe muscle aches, and fatigue consistent with the hantavirus prodromal phase. His condition deteriorates over the following days. The ship continues its planned itinerary.
April 11, 2026 — Death #1
First patient dies on board; attributed to natural causes
The Dutch passenger becomes the first fatality of the outbreak, dying aboard the ship. At this stage, the cause of death is attributed to generic natural causes. The ship's limited medical facility is not equipped to perform the diagnostic tests needed to identify hantavirus. His body remains on board the vessel.
April 13–15, 2026
MV Hondius stops at Tristan da Cunha
The ship makes a scheduled stop at Tristan da Cunha, one of the most remote permanently inhabited islands on Earth. At least one British passenger later suspected of Andes virus infection is thought to have been exposed during or around this stop, though the timing of exposure remains under investigation.
April 24, 2026
Stop at Saint Helena: body removed, passengers disembark
The MV Hondius arrives at Saint Helena, a British Overseas Territory. The body of the first victim is removed from the ship, two weeks after his death. His 69-year-old widow disembarks along with other passengers. Oceanwide Expeditions reports 30 disembarked passengers; the Dutch government reports approximately 40. The disembarked passengers are from 12 countries and return home before contact tracing begins. The widow is subsequently airlifted to Johannesburg, South Africa.
April 25–26, 2026 — Death #2
Widow dies in Johannesburg after being removed from KLM flight
The 69-year-old widow boards KLM flight KL592 from Johannesburg to Amsterdam on April 25, but is removed from the aircraft before takeoff due to her deteriorating medical condition. She had been on the plane for approximately 45 minutes. She dies in a Johannesburg hospital on April 26. Her death is later confirmed as caused by Andes hantavirus. GGD Kennemerland subsequently categorizes five flight attendants and 50 passengers seated within two rows of her as elevated-risk contacts.
April 27, 2026
British passenger evacuated from Ascension Island to South Africa
After a stop at Ascension Island, an ill British passenger is removed from the ship and flown to South Africa for hospital care. This patient is later placed in a critical but stable condition. The ship departs Ascension Island and continues north. The patient is subsequently confirmed PCR-positive for hantavirus while in the South African ICU.
May 1–7, 2026: Recognition and International Response
May 2, 2026 — Death #3
Third fatality: German woman dies on board
A German female passenger dies aboard the MV Hondius. The United Kingdom focal point notifies the WHO of a severe acute respiratory illness cluster on the ship. As of May 8, her body remains on board the vessel. The UK's notification triggers formal WHO outbreak monitoring and response protocols.
May 3, 2026
Ship docks at Praia, Cape Verde
The MV Hondius arrives at Praia, the capital of Cape Verde. Cape Verdean authorities announce medical support and the creation of an isolation area, but determine that local facilities are unable to handle a full-scale safe evacuation of the ship. No passengers disembark. Two doctors and one nurse make three trips to the vessel to provide additional care.
May 4, 2026
First positive hantavirus test result received
Gene sequencing identifies the Andes virus in at least one infected person on board. This is the first confirmed laboratory result linking the cluster to hantavirus. The WHO receives formal notification and begins coordinating international response. Contact tracing expands across 12 countries.
May 6, 2026
Andes virus formally confirmed; ship departs for Canary Islands
Full gene sequencing confirms the Andes virus as the causative pathogen. Three more passengers are evacuated by air ambulance to the Netherlands: a 56-year-old British national (later identified as ex-police officer Martin Anstee), a 41-year-old Dutch national (the ship's doctor), and a 65-year-old German national. Switzerland separately confirms a passenger who disembarked in Saint Helena tested positive, bringing the total infection count to eight. The ship departs Cape Verde for the Canary Islands. Four medical experts — including two epidemiologists from Italy and the Netherlands — board the vessel before departure to investigate the scope of viral spread. The Canary Islands president initially refuses entry; Spain's national government overrides this decision on humanitarian grounds.
May 7, 2026
Third evacuation flight arrives in Netherlands; flight attendant hospitalized
The third evacuated patient lands in the Netherlands and tests positive for the Andes virus, hospitalized at Radboud University Medical Center. A flight attendant from the April 25 KLM flight is admitted to Amsterdam University Medical Center on suspicion of infection. Singapore announces two residents who had been on the cruise are being tested. The WHO confirms 8 total cases (6 confirmed, 2 probable) in a media briefing.
May 8–11, 2026: International Evacuation and ECDC Update
May 8, 2026
CDC raises to Level 3; ship en route with 147 aboard
The US Centers for Disease Control and Prevention classifies the outbreak as a Level 3 emergency response. Spain finalizes evacuation plans coordinating with 22 countries and the WHO. The ship carries 147 individuals and one deceased body. A second British national in South Africa, who had been on the same KLM flight as the Dutch widow, tests positive. The KLM flight attendant tests negative. The Spanish health secretary confirms a symptomatic Spanish passenger hospitalized in Alicante, seated two rows from the deceased widow on flight KL592.
May 9, 2026
Ship approaches Tenerife; WHO updates to 8 cases
The MV Hondius is en route to the Port of Granadilla, Tenerife, and is expected to arrive in the early hours of May 10. The WHO reports eight suspected cases including six confirmed cases. Spain confirms evacuation aircraft from nearly all 22 countries are ready at Tenerife airport.
May 10, 2026
MV Hondius arrives at Tenerife; 7 evacuation flights depart; paratroopers reach Tristan da Cunha
The MV Hondius arrives at the Port of Granadilla around 05:30 WET. Passengers are transported by speedboat directly to the airport with no contact with island residents. The first evacuation flight departs at 13:31 local time. By late May 10, seven flights have transported 94 passengers to six European countries and Canada. Each country applies its own quarantine protocol. Separately, six paratroopers and two medical clinicians from the British Army's 16 Air Assault Brigade parachute from a RAF A400M Atlas onto Tristan da Cunha — delivering 3,300 kg of medical supplies to assist one resident suspected of Andes hantavirus infection. The ship departs for Rotterdam on May 11 for full disinfection; the body of the German passenger who died on board remains aboard.
May 11, 2026 — New Confirmed Cases
French national very critical; MV Hondius departs Tenerife; Spanish case confirmed — 7 confirmed, 9 total
WHO confirms the French patient is in "very critical condition." The MV Hondius departs Tenerife at approximately 20:00 WET with 25 remaining crew and 2 RIVM medics aboard, heading for Rotterdam for full decontamination (ETA May 17). Spanish health authorities announce 1 of 14 Spanish nationals tested positive for Andes hantavirus — 13 others testing negative. An asymptomatic American also tests positive, while a second American with mild symptoms remains a probable case. France raises its public health alertness level and identifies 22 high-risk contacts. ECDC issues its situation report: 7 confirmed, 2 probable, 0 suspected, 3 deaths — risk to the EU/EEA general population assessed as very low. Genome analysis by the Pathoplexus team shows all five patient sequences are highly similar, consistent with a single zoonotic spillover event.
May 12, 2026 — New Confirmed Case
Spanish case confirmed in hospital; 12 Nijmegen workers in isolation — 9 confirmed, 11 total
The Spanish national who tested positive on May 11 is confirmed symptomatic and hospitalized on May 12, bringing the total to 9 confirmed and 2 probable (11 total), with 3 deaths (ECDC). Separately, 12 healthcare workers at Radboud University Medical Center in Nijmegen, Netherlands, are placed in isolation after failing to comply with infection control protocols when treating a hantavirus patient. Repatriation of all passengers was completed on May 11. This raises concerns about potential secondary exposure at the facility, though no additional cases have been confirmed.
The MV Hondius hantavirus timeline represents one of the most complex multinational disease response operations in recent history — involving more than 20 governments, the WHO, ECDC, CDC, and multiple national health agencies coordinating simultaneously across at least three continents.
