No Confirmed Hantavirus Cases Among U.S. Passengers from MV Hondius as CDC Completes Interviews

U.S. passengers who were on the MV Hondius cruise ship remain in federal quarantine as of May 13, 2026. CDC officials held a briefing Wednesday urging the passengers to stay in quarantine until the end of the 42-day incubation period, which started Monday when they disembarked from the vessel.

Dr. David Fitter, incident manager for the CDC’s hantavirus response, said they are still interviewing the passengers to determine how closely they were exposed to the Andes hantavirus. That interview process is expected to last at least through Thursday.

“Currently, there are no state or federal quarantine orders that have been drawn,” Fitter said. ” Two of the passengers have been tested for the Andes strain. One who had symptoms and was sent to Emory University Hospital in Atlanta has tested negative.

In Nebraska, one person from the cruise ship who was initially taken to the Biocontainment Unit at the University of Nebraska Medical Center has been cleared to move to quarantine. Dr. Stephen Kornfeld, a passenger on the MV Hondius, told CNN on Wednesday that while he had tested “faintly positive” for hantavirus, he has since tested negative and was moved from the Biocontainment Unit to quarantine.

At least seven Americans who got off the ship earlier are quarantining at home in multiple states. Health departments have said they are in regular contact with the passengers quarantining at home as they monitor for symptoms. “We are working very closely with state and local health departments and the passengers that are home to ensure that they understand what is expected for them to monitor themselves,” Fitter said.
