WHO: Suspected hantavirus outbreak kills three on Atlantic cruise ship

scienceMay 4, 202624437

The World Health Organization says three passengers died and at least three others are ill aboard a cruise ship en route from Argentina to Cape Verde in a suspected hantavirus outbreak. Hantaviruses are rodent-borne pathogens that can cause hantavirus pulmonary syndrome, a severe respiratory illness typically contracted by inhaling dust contaminated with rodent urine or feces, and some South American strains have shown rare person-to-person transmission. WHO says authorities are testing samples from sick passengers and coordinating with the ship and national health agencies to confirm the cause and trace contacts. Confirmation matters because cruise ships concentrate people across international borders and hantavirus infections carry high fatality risk and require targeted infection-control and rodent-exposure measures rather than routine flu protocols.
