American Passengers From Hantavirus-Hit Cruise Ship, Including One Presumed Positive, Arrive in Nebraska for Evaluation A group of American passengers evacuated from a cruise ship affected by a hantavirus outbreak have arrived in the United States for medical evaluation, with health officials confirming that one passenger is presumed positive while another is showing symptoms. The passengers were flown in under strict biocontainment procedures and are now being assessed at a specialised federal quarantine and treatment facility in Nebraska. The group of 17 U.S. citizens was transported from the cruise ship to the University of Nebraska Medical Center UNMC in Omaha, a designated national treatment and quarantine hub for high-risk infectious diseases. Health authorities confirmed that at least one passenger tested mildly positive for the Andes strain of hantavirus, while another is experiencing mild symptoms consistent with early infection. Both individuals were placed in biocontainment units during the flight to minimise any potential risk of transmission.

Upon arrival, all passengers will undergo

Comprehensive medical screening
Laboratory testing
Risk classification low, medium, or high exposure
Continuous symptom monitoring

Officials said the evaluation will determine whether individuals require isolation at the Nebraska facility or can safely continue home quarantine under supervision. The Centers for Disease Control and Prevention (CDC) and the U.S. Department of Health and Human Services (HHS) are jointly overseeing the response. The outbreak occurred aboard the cruise ship MV Hondius, which reported multiple cases of hantavirus infection while sailing near the Canary Islands.

Multiple infections linked to the vessel
At least three deaths internationally
Several passengers either confirmed or suspected infected
Evacuations involving passengers of multiple nationalities
The strain involved, Andes virus, is rare and notable because it can in limited cases spread between humans through close contact. Despite the severity of the outbreak onboard the ship, U.S. and international health authorities continue to stress that the risk to the general public remains low.
Is primarily spread through rodents
Requires close or prolonged contact for rare human transmission
Is being managed through established containment protocols

Officials also emphasised that the response is not comparable to COVID-19, and there is no evidence of widespread community transmission.

Patients will remain under observation in Nebraska
Daily monitoring will continue for up to six weeks 42 days in line with WHO guidance
Contact tracing is ongoing across multiple countries
Final classification will determine isolation or release protocols

Health authorities say more updates will be released as laboratory results and clinical assessments progress.The arrival of exposed passengers in Nebraska marks a critical stage in managing the international hantavirus cruise ship outbreak, with medical teams now focused on early detection, isolation, and preventing any secondary spread. While one case is currently presumed positive, officials maintain that swift containment measures are working as intended.
