All 18 U.S.-resident passengers from the MV Hondius cruise ship linked to a hantavirus outbreak have returned to their home states after completing monitoring at the National Quarantine Unit, the University of Nebraska Medical Center said on Monday.  

The passengers were placed under observation following their return from the voyage, which health authorities had flagged as a potential exposure event. The first group arrived on 11 May, with two additional passengers admitted on 15 May.

The U.S. Centers for Disease Control and Prevention said no cases of hantavirus disease were detected among the monitored passengers.

Earlier this month, eight travellers had already completed a three-week monitoring period, while the remaining individuals were observed under public health protocols before being cleared to leave quarantine.

International health guidance

The World Health Organization recommends monitoring and quarantining high-risk contacts for up to 42 days after exposure, while advising low-risk contacts to self-monitor and seek medical attention if symptoms appear.

Health authorities continue to stress that early detection and isolation remain key in preventing potential outbreaks of hantavirus, a rare but serious disease transmitted primarily through rodent exposure.
