Latest Case
On May 16, 2026, Canada reported that a passenger of the cruise ship tested presumptively positive for Andes hantavirus, with the person already under quarantine and experiencing mild symptoms.
Outbreak Overview
The CDC is responding to a deadly hantavirus outbreak on a cruise ship in the Atlantic Ocean, reported on May 2, 2026, caused by Andes virus, which can lead to hantavirus pulmonary syndrome (HPS).
Global Cases
The identification of additional cases after former passengers and crew have returned to their home country is expected given the long incubation period of Andes hantavirus and the possibility that some infections occurred on board the ship.
Risk Assessment
To date, no cases of Andes virus have been confirmed in the United States as a result of this outbreak, and the overall risk to the American public and travelers is extremely low.
