Hantavirus on Cruise Ship: Evacuation of the MV Hondius

The outbreak likely originated before the voyage even began. A passenger probably contracted the virus during a shore excursion in Ushuaia, Argentina. Because the incubation period of the virus can last up to eight weeks, the illness initially went completely unnoticed. The Andes virus is unique because it can be transmitted from human to human through very close contact. On board, this led to further infections and posed enormous challenges for the crew and passengers.

The situation became particularly critical due to a stopover on the island of St. Helena in late April. There, 29 passengers left the ship and began their regular journey home. When the true cause of the illnesses on board became known, a massive, worldwide contact-tracing operation was launched. Health authorities across four continents had to locate and isolate the departed passengers as quickly as possible to prevent further spread.

The ongoing rescue and evacuation measures somewhat resemble a Hollywood movie. For a sick passenger on the extremely remote island of Tristan da Cunha, the British military even parachuted in doctors and medical equipment. Off Tenerife, the ship was not allowed to enter the port. The passengers left the ship on the port and starboard sides in small groups using the ship's own Zodiac inflatable boats. The strictest safety precautions were in place, and everyone involved wore hazmat suits.

The remaining passengers were flown back to their home countries in special aircraft, where they are now under strict quarantine. The MV Hondius itself is embarking on its final leg with a skeleton crew. It is heading back to its home port of Rotterdam, where it will undergo an extremely complex and complete decontamination. This incident impressively demonstrates how vulnerable expedition cruises can be, but it also proves that global crisis management works.
