A suspected hantavirus outbreak aboard a cruise ship traveling from Argentina to Cape Verde has resulted in three deaths, according to the World Health Organization as reported by the BBC. A 70-year-old male passenger on the MV Hondius fell ill and died after the vessel reached Saint Helena Island. His 69-year-old wife also became ill and later died in a hospital in Johannesburg, South Africa.

Hantavirus is a rodent-borne virus that spreads through inhalation of particles from dried rodent droppings. Professor Paul Griffin, Director of Infectious Diseases at Mater Health Services in Australia, told the Australian Broadcasting Corporation that hantavirus is not a common virus but can be severe. He noted that cruise ships provide favorable conditions for infection spread due to confined spaces and prolonged close contact among passengers.

Griffin added that since the COVID-19 pandemic, hygiene practices have improved, making hantavirus transmission among cruise passengers highly unusual.
