The MV Hondius cruise ship docked at the Rotterdam port on Monday, May 18, 2026, to undergo disinfection and quarantine following a hantavirus outbreak [1], [2].

The arrival of the vessel marks a critical step in containing a deadly virus that has plagued the ship and its occupants. The operation involves high-level biohazard protocols to prevent the pathogen from spreading into the Dutch population.

Personnel wearing white and purple protective suits, including Dutch health and quarantine officials, were seen working on the ship to prepare it for quarantine [1], [2]. These workers are tasked with disinfecting the vessel to neutralize the virus and ensuring the ship is safe for further processing [2], [3].

Reports regarding the number of people remaining on the vessel vary. According to Reuters, 25 crew members and two medical staff remained on board [1]. However, other reports indicated that nearly 150 people were trapped aboard the ship [4]. The discrepancy may stem from different stages of the evacuation process as the ship moved toward its final destination.

Earlier reports suggested the ship had been marooned off the coast of West Africa [4], but the vessel has now reached the Netherlands for official health interventions [1]. The hantavirus outbreak on board has been described as deadly, necessitating the current emergency response in Rotterdam [3].

Authorities are now focusing on the remaining personnel. The two medical staff members and the crew are being managed under strict quarantine guidelines to monitor for symptoms and prevent further transmission [1].

Dutch health and quarantine officials began disinfecting the MV Hondius after a deadly hantavirus outbreak.

The deployment of specialized biohazard teams in Rotterdam underscores the severity of hantavirus, a rare but potentially fatal respiratory disease. The contradiction in passenger counts suggests a chaotic evacuation process, while the ship's journey from West Africa to the Netherlands highlights the international logistical challenges of managing public health crises in maritime environments.
