Hantavirus Outbreak: US Implements Quarantines

Eighteen American passengers from the MV Hondius cruise ship are undergoing quarantine in U.S. healthcare facilities following a hantavirus outbreak that resulted in three deaths onboard.

As of May 13, 2026, 15 individuals, including one confirmed positive case, are isolated at the University of Nebraska Medical Center in Omaha, while two others are at Emory University Hospital in Atlanta. These measures are precautionary, as public health officials assess a low risk of broader community transmission.

The outbreak occurred during a South Atlantic voyage, with 11 people falling ill and at least nine confirmed hantavirus cases. The Andes virus, a strain of hantavirus, was detected, which, in rare instances, can transmit between humans, unlike more common forms spread by rodent droppings. Symptoms typically manifest between one and eight weeks post-exposure.

Passengers, including Boston photographer Jake Rosmarin, are expected to remain in specialized isolation units for up to 42 days. These facilities are designed for monitoring individuals exposed to serious infectious diseases. The remaining international passengers disembarked on May 10 and proceeded to quarantine in over 20 countries.
