One American passenger from the cruise ship MV Hondius tested positive for hantavirus following an outbreak on the vessel [2].
The incident highlights the complexities of managing infectious disease outbreaks in the cruise industry, where passengers from multiple countries can rapidly transport pathogens across international borders.
The MV Hondius was anchored near Tenerife in the Canary Islands, Spain, when the outbreak occurred [1, 5]. In response to the health crisis, authorities coordinated the quarantine and evacuation of passengers. A total of 17 American passengers were evacuated from the ship [1].
These passengers disembarked the vessel on May 10, 2026 [4]. The group arrived back in the U.S. at approximately 2:30 a.m. ET on Monday [6]. Following the evacuation, one of the American passengers tested positive for hantavirus [2]. This individual was flown to Omaha, Nebraska, but remained asymptomatic [1, 2].
Another American passenger reported mild symptoms, though they did not test positive for the virus [3]. While some reports suggested the test results for the positive passenger were inconclusive, primary health reporting confirmed the positive status [2, 3].
Public health officials monitored the returning passengers to prevent further spread. Hantavirus is typically transmitted to humans through contact with infected rodents or their droppings, a risk that can occur in various environments including ships. The positive passenger's asymptomatic status suggests the virus was detected before severe illness developed.

The detection of hantavirus on a cruise ship is an unusual event, as the virus is generally associated with rural environments and rodent infestations rather than maritime travel. The rapid evacuation and testing of the 17 U.S. citizens demonstrate a coordinated international health response aimed at containment. Because the positive case was asymptomatic, it underscores the importance of proactive screening in preventing potential community outbreaks after international travel.
