The Westerdam's Route and Destination
The cruise ship Westerdam was headed to Cambodia when a passenger tested positive for hantavirus in February 2020. The ship had departed from Hong Kong on February 1 and was scheduled to dock in Sihanoukville, Cambodia, on February 13. Instead, the ship was turned away by Cambodia and spent days at sea while ports across Southeast Asia refused to let it dock.
The Westerdam is a Holland America Line vessel that typically operates cruises through Asia. At the time of the hantavirus case, the ship was carrying roughly 1,400 passengers and 800 crew members. The positive case created a public health emergency that disrupted the planned itinerary and stranded passengers for longer than expected.
Key Takeaways
- The Westerdam was sailing from Hong Kong to Sihanoukville, Cambodia, when a passenger tested positive for hantavirus on February 12, 2020.
- Multiple ports in Southeast Asia refused to allow the ship to dock, including Cambodia, Thailand, Japan, and the Philippines, forcing it to remain at sea.
- The ship eventually docked in Sihanoukville on February 13 after Cambodia reversed its initial refusal, but only to disembark passengers.
- Hantavirus is a rare respiratory illness spread through contact with infected rodent droppings, not through person-to-person contact on a ship.
- The incident led to increased health screening protocols for cruise ships operating in Asian waters during that period.
Why Ports Refused the Ship
When news of the hantavirus case broke, ports across the region closed their doors to the Westerdam. Thailand, Japan, and the Philippines all denied the ship entry, citing health and safety concerns. The refusal was partly driven by fear and partly by the broader COVID-19 pandemic, which was beginning to spread globally at the same time and had already made ports cautious about incoming vessels.
Cambodia initially refused entry as well, but reversed that decision after international pressure and negotiations with Holland America Line. The reversal allowed the ship to dock in Sihanoukville, though only to disembark passengers. The crew remained on board while passengers left the ship to complete their journey home or continue their travels.
What Hantavirus Is and How It Spreads
Hantavirus is a serious respiratory illness caused by contact with infected rodent droppings, urine, or saliva. It does not spread from person to person through the air or casual contact. The virus is found in certain rodent populations, particularly in Asia, and human cases are rare. Symptoms include fever, muscle aches, and difficulty breathing, and they typically appear one to eight weeks after exposure.
The presence of a single hantavirus case on a cruise ship does not mean the virus is spreading among passengers. The infected passenger likely contracted the virus before boarding or from an environmental source on the ship, not from other travelers. This distinction was important but often lost in media coverage at the time, which created unnecessary alarm about the ship itself being a source of transmission.
The Timeline of Events
On February 1, 2020, the Westerdam departed Hong Kong with its scheduled destination of Sihanoukville, Cambodia. The ship was supposed to arrive on February 13. On February 12, while still at sea, a passenger developed symptoms and tested positive for hantavirus. Holland America Line notified regional health authorities and began working to find a port that would accept the ship.
Over the next several days, Thailand, Japan, and the Philippines all refused entry. The ship remained at sea while negotiations continued. On February 13, Cambodia agreed to allow the ship to dock in Sihanoukville, and passengers began disembarking. The crew remained on the ship for additional health checks and cleaning. By February 14, most passengers had left the vessel, and the when ready crisis had passed.
How This Affected Cruise Operations in Asia
The Westerdam incident occurred during a period of heightened concern about infectious disease on cruise ships. The COVID-19 pandemic was accelerating globally, and the Diamond Princess cruise ship had already become a major outbreak site in Japan just weeks earlier. These two events combined to make ports and health authorities far more cautious about allowing cruise ships to dock.
In the months following the Westerdam incident, cruise lines operating in Asian waters implemented stricter health screening procedures. Passengers were screened for fever and respiratory symptoms before boarding. Ships were required to report any suspected illness to port authorities before arrival. Some itineraries were canceled or rerouted to avoid ports with strict entry requirements. These measures remained in place for months as the pandemic worsened.
What Passengers Experienced
Passengers on the Westerdam faced uncertainty and disruption to their vacation plans. Many had booked the cruise expecting to visit multiple ports and enjoy a typical Southeast Asian itinerary. Instead, they spent extra days at sea waiting for a port to accept the ship. Once Cambodia allowed docking, passengers were able to disembark, but many faced complications getting home, particularly as COVID-19 travel restrictions began to take effect.
Holland America Line offered refunds and compensation to affected passengers. The cruise line also covered costs for passengers who needed to extend their stay or arrange alternative transportation. Despite the compensation, the experience highlighted the vulnerability of cruise passengers to sudden health emergencies and the speed with which international cooperation can break down during a public health crisis.
Frequently Asked Questions
Did anyone else on the Westerdam get hantavirus?
No confirmed cases of hantavirus were reported among other passengers or crew members on the Westerdam. The single positive case was isolated, and no secondary transmission occurred on the ship. This supported the understanding that hantavirus does not spread easily from person to person.
Is hantavirus common on cruise ships?
Hantavirus cases on cruise ships are extremely rare. The virus is found in rodent populations and is not typically associated with maritime environments. The Westerdam case was unusual and received significant media attention precisely because it was so uncommon.
Could the hantavirus have come from the ship itself?
It is possible the passenger was exposed to rodent droppings somewhere on the ship, but this was not confirmed. The passenger may have contracted the virus before boarding. Cruise ships do undergo regular pest control and sanitation, though rodents can occasionally be present in any large structure.
Did the Westerdam incident change cruise ship health policies?
The incident contributed to increased health screening at ports, but the larger driver of policy changes was the COVID-19 pandemic, which occurred at the same time. Cruise lines now screen passengers for fever and respiratory symptoms before boarding and require crew health monitoring throughout voyages.
