The “Atlantic Odyssey” was a luxury expedition cruise aboard the MV Hondius that began as a dream bird-watching trip but ended in a deadly hantavirus outbreak. The voyage departed from Ushuaia, Argentina,
on April 1, 2026, carrying 149 passengers and crew from 23 nations. What was meant to be a 33-day journey to remote islands like South Georgia and Tristan da Cunha became a harrowing public health crisisas a rare, rodent-borne virus swept through the vessel. All you need to know from the Wall Street Journal, Al Jazeera and other reports.
Atlantic Odyssey: The timeline
- April 1: The MV Hondius departs Argentina for the South Atlantic.
- April 6: A 70-year-old Dutch passenger begins showing flu-like symptoms (fever, headache, diarrhea).
- April 11: The passenger dies on board from sudden respiratory failure. The captain initially tells guests the ship is “safe” and the case is “isolated”.
- Late April: More passengers fall ill. The deceased man’s wife disembarks at Saint Helena but collapses at a Johannesburg airport and dies shortly after.
- Early May: The World Health Organization (WHO) confirms a hantavirus outbreak. At least three people have died and eight others are confirmed or suspected to be infected.
The “Nightmare” Disease
Hantavirusesare typically transmitted via rodent droppings or urine, but health officials identified the Andes strain in this outbreak.
Human-to-Human Spread: Unlike most strains, the Andes virus is known for rare, limited transmission between people in close contact, which likely occurred in the tight quarters of the ship.
Severity: Initial symptoms mirror the flu but can rapidly progress to Hantavirus Pulmonary Syndrome (HPS), where the lungs fill with fluid, causing a mortality rate of nearly 40%.
What is Hantavirus Pulmonary Syndrome?
Hantavirus Pulmonary Syndrome (HPS) is a severe, sometimes fatal respiratory disease caused by hantaviruses. People become infected through contact with infected rodents or their urine and droppings, most often by breathing in contaminated dust while cleaning or working in enclosed spaces. The illness begins with flu-like symptoms including fever, fatigue, and muscle aches in the large muscle groups like the thighs and back. Within a few days, the disease progresses rapidly to a late stage where the lungs fill with fluid, causing severe shortness of breath and coughing. Because there is no specific antiviral treatment, cure, or vaccine, early medical intervention is vital. Patients often require intensive care and oxygen therapy to support breathing while the body fights the virus.
12 countries on alert
The World Health Organization (WHO) and local health agencies have issued alerts for 12 countries The following countries have been alerted to monitor returning passengers or individuals who may have been exposed:
Americas: Canada, Saint Kitts and Nevis, United States
Europe: Denmark, Germany, Netherlands, Sweden, Switzerland, Türkiye, United Kingdom
Asia/Pacific: New Zealand, Singapore
What is the current status of the voyage?
The shipwas recently stranded off the coast of Cape Verde after local authorities denied it permission to dock.
Medical teams in protective gear have evacuated several critically ill patients via air ambulance to South Africa and the Netherlands.
The ship is now bound for the Canary Islands, where Spanish authorities have agreed to let passengers disembark under strict medical supervision for repatriation to their home countries.
