An American passenger on the MV Hondius cruise ship tested positive for hantavirus after being evacuated to the United States for quarantine [1], [2].
The incident highlights the risks of rare zoonotic diseases in confined travel environments and the rapid mobilization of biocontainment resources to prevent a wider domestic outbreak.
Health officials acted to prevent the spread of the virus after an outbreak occurred on the MV Hondius, which was anchored near Tenerife, Spain [1], [3]. The positive case was identified as the Andes virus [2], [3]. Following the diagnosis, the passenger was placed in a specialized biocontainment unit in Nebraska [2].
Passengers disembarked from the vessel on May 10, 2026 [1], [2]. On May 11, 2026, 18 passengers were flown to the U.S. to undergo monitoring and quarantine [1]. While one person tested positive for the virus [2], another passenger reported experiencing mild symptoms [3].
Medical monitoring for the evacuated group is being conducted across two states. Facilities in Nebraska and the Atlanta area of Georgia are overseeing the passengers [1], [2].
U.S. health officials coordinated the transport and isolation of the travelers to ensure the virus did not spread beyond the quarantined individuals. The use of a biocontainment unit in Nebraska underscores the severity with which officials are treating the Andes virus strain.

The Andes virus is a specific strain of hantavirus that, unlike many other strains, has shown the potential for person-to-person transmission in certain outbreaks. The decision to utilize a high-level biocontainment unit and quarantine 18 passengers suggests that health officials are prioritizing the prevention of community spread over the risk of over-reaction, given the virus's potential for severe respiratory distress.
