WHO Links 11 Hantavirus Cases, 3 Deaths to Cruise Ship as U.S. Monitors 41
10 articles · Updated · CNBC · May 14
Eleven hantavirus cases tied to the MV Hondius cruise outbreak have been reported to WHO, including eight confirmed infections and three deaths, while 41 people in the U.S. are under monitoring with no confirmed domestic cases.
WHO said the outbreak likely began with a Dutch couple infected during a bird-watching trip in Argentina, Chile and Uruguay before boarding; the Andes strain can spread between people, but usually only through close, prolonged contact.
One-to-six-week incubation means additional cases could still emerge, though experts say containment measures and targeted monitoring make wider spillover unlikely and that the virus does not spread like Covid, flu or measles.
The episode has still sharpened criticism of U.S. outbreak readiness after roughly 10% CDC workforce cuts, leadership vacancies and the Trump administration's withdrawal from WHO, with some experts calling the CDC response delayed and fragmented.
After leaving the WHO, how are new U.S. health pacts affecting the global fight against deadly viruses?
With a 50% fatality rate, how close are scientists to a vaccine for the human-to-human spreading hantavirus?
Andes Hantavirus on MV Hondius: May 2026 Outbreak, Unique Transmission, and International Containment Efforts
Overview
As of May 14, 2026, the hantavirus outbreak linked to the MV Hondius cruise ship has raised immediate concerns about new cases and the need to monitor exposed individuals. The outbreak involves the Andes virus, which is unique among hantaviruses for its rare ability to spread from person to person. Experts from the World Health Organization believe such transmission may have occurred on the ship, and the outbreak was officially reported after the third passenger died. With an incubation period ranging from four to 42 days, ongoing vigilance is essential to identify and manage any further cases among those exposed.
