A suspected outbreak of hantavirus aboard a cruise ship in the Atlantic Ocean has resulted in the deaths of three passengers, according to the World Health Organization (WHO). Several others have reported illness, with at least one British passenger in intensive care. Investigations are underway to determine the source of the outbreak, which is linked to the rare hantavirus often associated with rodent transmission. Officials have faced criticism for delaying medical evacuations as they probe the threat posed by the virus. The cruise ship remains moored off the coast of Africa while health authorities assess the situation.
