Seventeen American passengers returned to the United States early Monday after being evacuated from the MV Hondius cruise ship, which has been linked to a hantavirus outbreak that affected multiple nationalities and resulted in several deaths. The passengers arrived following a U.S.-government arranged medical repatriation flight from the Canary Islands to Nebraska, where they were transferred to a federal quarantine and treatment facility.
The cruise ship, operated by Oceanwide Expeditions, departed southern Argentina on April 1st and travelled across remote areas of the South Atlantic before reports of illness emerged. Health authorities confirmed that at least three people have died in connection with the outbreak, which has involved cases of the rare Andes strain of hantavirus, a variant capable of limited person-to-person transmission.
During the repatriation flight, one American passenger tested mildly positive for the virus, while another developed symptoms consistent with infection. Both individuals were placed in biocontainment units on board the aircraft as a precaution. Upon landing at Offutt Air Force Base near Omaha, most of the 17 passengers were transported to the National Quarantine Unit at the University of Nebraska Medical Center for evaluation and monitoring. The symptomatic passenger was directed to a separate specialized treatment facility.
Health officials indicated that the returning passengers had been isolated in their cabins prior to evacuation and would remain under observation for several weeks due to the virus’s incubation period, which can extend up to 42 days. Some individuals may undergo monitoring at home under supervision from local health departments, depending on their risk assessments.
The outbreak has prompted coordinated international responses, with other countries also repatriating citizens. French authorities reported that a passenger tested positive during a separate evacuation flight, while British and Spanish nationals have been placed under medical supervision in their respective countries.
The World Health Organization assessed the overall public risk as low, noting that although Andes hantavirus can spread between humans, transmission typically requires prolonged close contact with symptomatic individuals. Experts emphasized that the situation differs significantly from highly contagious respiratory pandemics, though they cautioned that careful monitoring remains essential.
U.S. health officials have deployed epidemiology teams to assist with risk assessments and contact monitoring, while state health departments have been notified to track passengers who disembarked earlier. The source of the outbreak on the cruise ship remains under investigation.
