Eighteen Americans quarantined after returning from hantavirus‑infected cruise ship
Eighteen U.S. citizens who were aboard a cruise liner that experienced a hantavirus outbreak have been placed under quarantine at a federal biocontainment facility in Omaha, Nebraska, after returning to the United States on Sunday. One passenger remains hospitalized in the university’s high‑security isolation unit after testing positive for the virus, which is transmitted through aerosolized rodent excreta.
The cruise, which departed from Miami on April 28 and docked in Cartagena, Colombia, reported several cases of severe respiratory illness among passengers and crew, prompting the ship’s medical team to alert the Centers for Disease Control and Prevention (CDC) on May 3. The CDC subsequently issued a travel advisory and coordinated with the U.S. Customs and Border Protection to screen returning travelers.
CBS News correspondent Ian Lee reported that the quarantined individuals are being monitored for symptoms and will undergo daily PCR testing. The CDC’s Dr. Sandra Muñoz told Reuters that “the incubation period for hantavirus ranges from one to three weeks, and we are exercising extreme caution to prevent any community spread.”
Infectious‑disease experts, including Dr. Alan Peters of the University of Chicago, note that while hantavirus cases in the U.S. are rare—averaging 20–30 annually—outbreaks on cruise ships pose unique challenges due to close quarters and international travel routes. Public‑health officials emphasize the importance of rodent control measures aboard vessels and rapid reporting of respiratory illnesses.
The CDC will release a full investigation report by early July, and the cruise line has pledged to refund all affected passengers. Authorities will also evaluate whether additional screening protocols are needed for future voyages, especially those that dock in regions with known rodent‑borne disease activity.
