WHO confirms five hantavirus cases on cruise ship; more expected due to long incubation period
WHO says the outbreak is likely limited, with 5 confirmed cases and 3 suspected after three deaths aboard the cruise ship.
- On Saturday, the MV Hondius cruise ship is scheduled to arrive in Tenerife, Spain, following a confirmed Andes-strain hantavirus outbreak that has killed three passengers and infected five others confirmed by the World Health Organization.

- Dr. Stephen Kornfeld, an oncologist from Bend, Oregon, described the international response as "massive and coordinated," while the World Health Organization currently assesses the global public-health risk as low.
- Authorities are tracing passengers who disembarked at Saint Helena on April 24, 2026, while Spanish officials prepare to receive remaining travelers in a fully isolated zone ensuring "absolutely no possibility of contact" with residents.
- Given the Andes virus's incubation period of up to six weeks, the World Health Organization continues monitoring the situation and warns additional cases remain possible as health agencies maintain strict isolation protocols globally.
