American Passengers from Hantavirus-Affected Cruise Ship Quarantined in Nebraska

Quarantine Measures for Passengers

On Monday morning, sixteen American passengers evacuated from the hantavirus-affected MV Hondius cruise ship arrived at the University of Nebraska Medical Center’s Davis Global Center. This facility is the only federally funded quarantine unit in the U.S. specifically designed for high-consequence infectious diseases. Previously, it has treated Ebola patients and some of the first Americans infected with COVID-19 from the Diamond Princess cruise ship. Currently, it is crucial in managing the Andes strain of hantavirus, which is known for its limited person-to-person transmission.

As reported by the Department of Health and Human Services, one passenger tested “mildly PCR positive” for the virus but is asymptomatic, while another exhibited mild symptoms that have since resolved. Both individuals were transported in biocontainment units as a precaution.

Dr. Michael Ash, CEO of Nebraska Medicine, detailed the strict protocols in place: “Our quarantine unit can accommodate 20 asymptomatic individuals, each with their own oxygen air exchange systems, ensuring safe monitoring. If any patient becomes ill, they will be moved to our biocontainment unit, which can provide care up to intensive care levels.” Each room is equipped with negative air pressure, dedicated air supplies, and HEPA filtration systems. Waste and water lines are specially treated, and staff utilize enhanced personal protective equipment with independent air supplies.

Passengers will be closely observed for symptoms such as fever, muscle aches, fatigue, and respiratory issues. Those who show symptoms will undergo PCR testing. Asymptomatic individuals with low exposure risk may not need routine testing but will still be monitored. The incubation period for the Andes strain can extend up to 42 days. After their initial evaluation in Omaha, most passengers are expected to return home, where they will be monitored daily by local health departments for the entire 42-day period. Private transportation will be arranged for those cleared to leave.

Health officials emphasize that the risk to the general public remains very low. Transmission of the Andes strain has only been documented through prolonged, close contact with symptomatic individuals. Dr. Ash expressed confidence in the facility’s capability to handle the situation: “We have successfully treated highly infectious patients before. We are well-prepared for this and conduct regular drills and training for our staff. This is part of our identity.” This operation reflects a well-coordinated national response to an international health incident, with the passengers’ stay in Nebraska expected to be brief before they transition to monitoring in their home states, while authorities continue to track the broader outbreak associated with the MV Hondius.
