They will remain under phone surveillance for 45 days from exposure
Two Singaporean men who sailed aboard the MV Hondius during a deadly Andes hantavirus outbreak have emerged from weeks of isolation, cleared by negative tests and the careful watch of public health authorities. The ship, which departed Argentina in early April, became the site of an outbreak that has claimed three lives and infected thirteen people across multiple nationalities. For these two men, aged 67 and 65, the ordeal spanning more than two months closes not with a final door but with a quieter vigil — forty-five days of phone surveillance to honor the full length of what the virus might yet reveal. Their release is a small, hard-won relief set against the sobering reminder that in the close quarters of shared human travel, disease moves with us.
- A cruise ship departure from Patagonia in early April quietly carried the seeds of an outbreak that would eventually claim three lives and infect thirteen people across multiple countries.
- Two Singaporean passengers, returning home weeks apart in early May, were immediately placed in isolation — their first negative tests offering hope but not yet certainty, given the virus's long and unpredictable incubation window.
- Health authorities held firm, refusing to release the men on initial results alone, knowing that Andes hantavirus can take weeks to declare itself and that a premature clearance could carry real consequences.
- Both men have now tested negative a second time and walked free from the National Centre for Infectious Diseases, though a 45-day surveillance window from last exposure means the watch is not entirely over.
- The broader MV Hondius outbreak remains a live concern — thirteen confirmed cases and three deaths underscore how swiftly a severe pathogen can ripple outward from a single vessel into the wider world.
Two Singaporean men who were passengers aboard the MV Hondius when it left Ushuaia, Argentina on April 1 have been released from quarantine after testing negative for Andes hantavirus. The Communicable Diseases Agency confirmed their clearance on Saturday, ending an isolation period that had begun the moment they landed back in Singapore — one on May 2, the other on May 6.
Upon arrival, both men were admitted directly to the National Centre for Infectious Diseases. Initial tests returned negative, but authorities kept them under observation given the virus's lengthy incubation period. A second round of negative results, combined with the completion of their quarantine stay, was enough to allow their release.
Their freedom, however, comes with conditions. Both men will remain under phone surveillance for the duration of a 45-day window measured from their last potential exposure — a timeline that mirrors the maximum known incubation period for hantavirus and ensures that any late-emerging symptoms would be caught quickly.
The outbreak that shadowed their journey has been severe. The World Health Organization recorded 13 confirmed cases linked to the MV Hondius as of late May, with three deaths among passengers and crew drawn from multiple countries. For the two Singaporean men, more than two months passed between boarding in early April and walking free in early June — a long arc of uncertainty now giving way, cautiously, to relief.
Two Singaporean men who spent weeks aboard a cruise ship struck by a deadly virus outbreak have been cleared to leave isolation. The pair, aged 67 and 65, completed their quarantine on Saturday after testing negative for hantavirus, the Communicable Diseases Agency confirmed. Both men had been passengers on the MV Hondius when it departed Ushuaia, Argentina on April 1, before the vessel became the site of an outbreak of Andes hantavirus—a particularly severe strain of the disease.
The men arrived back in Singapore on separate dates in early May, with one touching down on May 2 and the other on May 6. Upon arrival, they were immediately admitted to the National Centre for Infectious Diseases, where they underwent initial testing. Those first tests came back negative, but the agency kept them under observation as a precaution. The virus has a long incubation period, and health officials needed to be certain before releasing them.
Now that they have tested negative again and completed their quarantine stay, the men are free to return to their lives. However, their monitoring is not entirely finished. They will remain under phone surveillance for the remainder of a 45-day observation window measured from their last potential exposure to the virus. This extended timeline reflects the maximum known incubation period for hantavirus infection—the window during which symptoms can still emerge.
The outbreak aboard the MV Hondius has proven serious. As of late May, the World Health Organization reported 13 confirmed cases linked to the cruise ship, with three people having died. The vessel carried passengers and crew from multiple countries, meaning the virus's reach extended far beyond Argentina's shores. For the two Singaporean men, the ordeal has lasted more than two months from the time they boarded in early April until their release from quarantine in early June.
Their clearance represents a small measure of relief in what has been a tense situation for everyone who was aboard the ship. The men are well and have shown no signs of infection. Still, the broader outbreak serves as a reminder of how quickly infectious disease can spread in the confined environment of a cruise ship, and how carefully health authorities must monitor those who may have been exposed.

Both of them are well, and have tested negative for hantavirus, including the Andes virus, before release from quarantine— Communicable Diseases Agency
The Hearth Conversation Another angle on the story
Why did these two men need to stay in quarantine if they tested negative when they first arrived?
Hantavirus has a long incubation period—up to 45 days. Someone can be infected but not show it yet. The agency couldn't be sure they were truly safe until more time had passed and they tested negative again.
So the initial negative test wasn't enough?
Exactly. It's like checking someone's temperature when they walk in the door. If they're in the early stages of infection, the test might miss it. That's why they stayed isolated at the National Centre for Infectious Diseases.
And now they're completely free?
Free from quarantine, yes. But they'll be on phone surveillance for the full 45 days from their last exposure. It's a lighter touch than isolation, but health officials are still watching.
How serious was the outbreak on the ship itself?
Thirteen cases confirmed, three deaths. That's significant for a cruise ship environment where people are living in close quarters. The virus spread among passengers and crew from different countries.
What does it mean that these two men are Singaporean but were on an Argentine ship?
Cruise ships are international spaces. People from all over the world board them. When an outbreak happens, it doesn't stay contained to one country—it travels home with the passengers.
