The MV Hondius cruise ship docked in Rotterdam on Monday, May 18, 2026, for disinfection and crew quarantine following a deadly hantavirus outbreak [4][5].
The arrival marks the end of a high-risk maritime health crisis that tested international quarantine protocols and the ability to manage rare viral infections in isolated environments.
The vessel reached the port in the Netherlands after a journey spanning seven weeks and 8,500 miles [3]. During the voyage, a hantavirus outbreak infected up to 11 people [1], a figure corroborated by reports stating nearly one dozen individuals were affected. Three people died as a result of the infections [2].
Currently, 25 crew members and two medical staff remain on board the ship [4]. These individuals are subject to quarantine measures as health officials work to ensure the virus is contained. The ship is undergoing a comprehensive disinfection process to eliminate any remaining viral presence before the vessel is cleared for future use [6].
Hantavirus is typically transmitted to humans through contact with infected rodents. The containment of such an outbreak on a cruise ship is complex due to the enclosed nature of the environment, and the movement of passengers and crew through shared spaces.
Rotterdam port authorities are coordinating with medical teams to monitor the remaining crew. The process involves strict biohazard protocols to prevent the virus from spreading into the city's population upon the crew's eventual disembarkation.
“Three people died as a result of the infections”
This incident highlights the vulnerability of the cruise industry to zoonotic diseases, where a single point of contamination can lead to a cluster of severe illness in a confined space. The requirement for a full-ship disinfection and crew quarantine in a major port like Rotterdam underscores the stringent public health measures necessary to prevent rare, high-mortality viruses from entering urban centers via international travel hubs.
