Hantavirus cruise ship update: 5 leave Nebraska quarantine unit

Five American cruise ship passengers exposed to hantavirus are leaving a Nebraska quarantine facility.

U.S. health officials say they will complete monitoring at home after remaining symptom-free.

They arrived in Nebraska three weeks ago following a deadly hantavirus outbreak on a South Atlantic cruise.

The virus usually spreads through rodent droppings, but the Andes virus may spread between people in rare cases.

Thirteen cases, including three deaths, are linked to the ship.

There have been no U.S. cases connected to the ship, and the risk remains low.

Federal officials arranged non-commercial travel with biocontainment measures for the five passengers.
