Seventeen Americans evacuated from the MV Hondius cruise ship were flown back to the United States and taken to University of Nebraska Medical Center/Nebraska Medicine in Omaha after a deadly hantavirus outbreak led to multiple deaths and international repatriations. The U.S. Department of Health and Human Services confirmed one evacuee tested positive for hantavirus without symptoms and another had mild illness, and French Health Minister Stephanie Rist reported a French passenger’s condition worsened after repatriation. Federal and local teams are running clinical assessments, employing biocontainment measures, and monitoring contacts as the situation unfolds.
A motorcade of emergency vehicles moved the 17 Americans to ASPR Regional Emerging Special Pathogen Treatment Center facilities at University of Nebraska Medical Center/Nebraska Medicine in Omaha, where specialized isolation and monitoring are available. HHS noted in a Sunday night on X that those two Americans traveled in the plane’s biocontainment unit “out of an abundance of caution.” “Each individual will undergo clinical assessment and receive appropriate care and support based on their condition,” the post added, underlining the staged response on arrival.
A Nebraska Medicine Facebook post issued on Sunday night stated, “One passenger will be transported to the Nebraska Biocontainment Unit upon arrival, while other passengers will go to the National Quarantine Unit for assessment and monitoring.” The post continued, “The passenger who is going to the Biocontainment Unit tested positive for the virus but does not have symptoms. They were managed separately from other passengers during transport using appropriate biocontainment measures. They will be monitored in the Biocontainment Unit out of an abundance of caution and follow-up testing will be performed.” Those exact steps reflect a cautious approach to isolation and testing.

The flight carrying the Americans touched down early Monday morning after evacuations from the cruise ship, and officials say three people have died since the outbreak began. French Health Minister Stephanie Rist said a French passenger who tested positive saw her health decline overnight in the hospital after being repatriated, and that she developed symptoms while flying to Paris. International coordination to move and care for passengers has complicated logistics but allowed for rapid transfer to specialized care facilities.
The Centers for Disease Control and Prevention explains the virus at the center of concern: “Andes virus is a type of hantavirus spread by rodents in South America and, less commonly, by other infected people. The rodents that carry Andes virus have not been found in the United States. It can cause a severe respiratory disease in people, called Hantavirus Pulmonary Syndrome (HPS).” That description frames both why the virus prompted swift isolation and why officials emphasize limited geographic risk within the U.S.
On person-to-person spread, the CDC is direct: “Andes virus is the only type of hantavirus that is known to spread person-to-person. This spread is usually limited to people who have close contact with a sick person. This includes direct physical contact, prolonged time spent in close or enclosed spaces, and exposure to the sick person’s body fluids.” Those limits help public health teams prioritize who needs monitoring and who can be safely released from quarantine.
Officials say the single asymptomatic positive case and the one with mild symptoms were handled separately during transport, highlighting layered containment steps designed to prevent onward transmission. Local medical teams in Omaha will run follow-up testing and continue monitoring patients in the Biocontainment Unit and the National Quarantine Unit as needed, while epidemiologists review exposure histories from the ship and the evacuation flight. The goal is to find any close contacts who might need testing or isolation.
Beyond patient care, public health authorities are coordinating surveillance and communications to ensure clinicians and hospitals are alert to hantavirus symptoms without causing undue alarm. Rodent-borne transmission dominates the risk picture, and the absence of the Andes virus rodent hosts in the U.S. reduces the likelihood of local spread, but agencies remain watchful for any sign of person-to-person transmission. Hospitals with isolation capacity and experienced staff in places like Omaha play a key role when rare, severe infections appear among returning travelers.
