A New Zealand passenger from hantavirus cruise ship quarantines in Taiwan as health officials monitor the individual for symptoms of a rare and potentially deadly respiratory disease. The passenger, who traveled aboard the MV Hondius, is currently being held in hospital quarantine after Taiwanese authorities were notified of their arrival and previous exposure to the virus.
Despite the strict isolation, the Taiwan Centers for Disease Control (CDC) confirmed on Friday that the individual has tested negative for the virus and remains asymptomatic. The precautionary measure comes as a result of the specific strain of hantavirus involved, which is among the few known to be capable of spreading between humans.
The passenger arrived in Taiwan on May 7, several weeks after disembarking from the MV Hondius in Saint Helena on April 24. The Taiwan CDC was alerted to the person’s presence by New Zealand authorities on Wednesday, leading to an immediate hospital admission to ensure public safety and individual health monitoring.
Precautionary measures and quarantine timeline
The decision to hospitalize the passenger, despite a negative test result, is rooted in the biological nature of the virus. According to Tseng Shu-hui, a spokeswoman for the Taiwan CDC, the individual will remain in quarantine until June 6 to cover the full window of potential infection.
The primary concern for health officials is the virus’s potential incubation period, which can extend up to 42 days. Because the passenger was exposed to other travelers on the cruise ship, authorities are maintaining a conservative approach to avoid any risk of community transmission.
Tseng noted that the risk of the passenger developing the illness is currently considered low. “At present, we believe their probability of developing the disease is relatively low,” Tseng said. “Their last exposure with the other passengers was on the 25th (of April), which is about 20 days ago.”
While the Taiwan CDC has confirmed the quarantine, officials have declined to release specific personal details, including the passenger’s age, gender, or the specific hospital location, citing privacy concerns. Similarly, New Zealand’s de facto embassy in Taipei has declined to comment on the matter.

The MV Hondius voyage and the Andes strain
The MV Hondius began its journey on April 1, setting sail from Argentina and charting a course across the Atlantic Ocean. During the voyage, the ship became linked to an outbreak of the Andes strain of hantavirus, a severe respiratory disease typically transmitted to humans through contact with the urine, feces, or saliva of infected rodents.
What distinguishes the Andes strain from other hantaviruses is its rare ability to spread via human-to-human contact. This characteristic prompted heightened vigilance from health authorities in multiple jurisdictions, including Hong Kong, which recently increased rodent surveillance measures despite having no local residents on the affected vessel.
To date, the global death toll associated with this specific outbreak remains at three. While the disease is grave, health officials have been quick to dismiss comparisons to the Covid-19 pandemic, noting that the transmission dynamics and overall risk to the general public are significantly lower.
| Date | Event |
|---|---|
| April 1 | MV Hondius departs from Argentina |
| April 24 | Passenger disembarks in Saint Helena |
| May 7 | Passenger arrives in Taiwan |
| May 15/16 | Taiwan CDC notified; passenger admitted to hospital |
| June 6 | Scheduled end of hospital quarantine |
Understanding the public health risk
Medical experts emphasize that while Notice currently no vaccines or specific antiviral treatments for the Andes strain, the broader risk to public health remains low. The virus does not spread as easily as common respiratory infections, and the number of cases remains extremely limited.
CDC director-general Lo Yi-chun informed reporters that the passenger in question did not return to New Zealand immediately after leaving the cruise ship. However, the director-general did not provide specific details regarding the travel route the passenger took to reach Taiwan.
The current strategy in Taiwan focuses on containment and observation. By isolating the individual for the duration of the maximum incubation period, health authorities can ensure that any delayed onset of symptoms is managed within a controlled clinical environment, preventing any accidental exposure to the public.
For those seeking more information on hantavirus symptoms and prevention, the Centers for Disease Control and Prevention (CDC) provides comprehensive guidelines on avoiding rodent-borne illnesses.

The next official update from the Taiwan CDC is expected following the conclusion of the passenger’s quarantine on June 6, provided no symptoms develop in the interim.
