Passengers are isolating aboard a cruise ship on which a suspected outbreak of hantavirus has killed three people, its operator said Monday, after Cape Verde refused them entry. Read More

WHO says seven confirmed or suspected cases of hantavirus on MV Hondius, including three passengers who died

• What is hantavirus, the infection thought to have killed three on cruise ship?

A British crew member was in need of urgent medical care and a passenger from the UK remained in a critical but stable condition following a suspected outbreak of hantavirus on a luxury cruise ship in the Atlantic Ocean.

Three people have died and medics on Monday were scrambling to evacuate two others from the MV Hondius, which set off in March from southern Argentina carrying 149 people from 23 countries. The crisis emerged late on Sunday after the World Health Organization (WHO) said it was investigating a suspected outbreak.

A cluster of hantavirus infections linked to a cruise ship in the Atlantic Ocean has left three people dead and several others seriously ill, prompting an alert from the World Health Organization and raising questions about how a rare rodent-borne disease might spread in such an unusual setting.

PARIS, May 4 — Three people have died and three are ill after a Netherlands-based cruise ship was ‌hit by a suspected outbreak of hantavirus, authorities and media reports said on Sunday.

Here is information about the virus.

Spread by rodents

Hantavirus is primarily spread by rodents ‌but can be transmitted between people in rare cases, according to the World Health Organisation.

People most typically become infected when virus in rodent droppings, saliva and urine becomes airborne, such as when areas where rats and mice have nested are swept out.

According to The Lancet medical journal, the name comes from the Hantan River area of South Korea, where the virus was identified in the 1970s.

Can be fatal

Hantavirus is a family of viruses that cause two illnesses, one that primarily ‌affects the lungs and the other that attacks the kidneys. The ⁠first gets the most attention because ⁠it has a high fatality rate of about ⁠40 per cent.

Hantavirus pulmonary syndrome, the ⁠respiratory illness, is most ⁠commonly found in North and South America.

According to the Canadian government, about 200 cases of hantavirus pulmonary illness occur each year worldwide.

Concert ⁠pianist Betsy Arakawa, wife of actor Gene Hackman, died from hantavirus pulmonary syndrome in New Mexico in 2025, according to autopsy results.

Symptoms

Hantavirus usually begins with flu-like symptoms, such as fatigue and fever, one to eight weeks after exposure, according to the CDC.

Four to 10 days later, ⁠coughing, shortness of breath and fluid in the lungs appear.

Diagnosis in the first 72 hours of infection is difficult, the CDC says, ⁠so symptoms can easily be mistaken for flu.

Treatment

There is no specific ⁠therapy for ⁠hantavirus infection, so treatment focuses on supportive care including rest and fluids. Patients may need breathing support such as a ventilator.

Prevention

Experts say exposure to hantavirus ‌can be minimised by deterring and eliminating rodents from areas where people are. Avoid vacuuming or sweeping dried droppings, which can aerosolise the virus. — Reuters

Three passengers of the MV Hondius died after showing symptoms of the rare disease. Health authorities confirmed two cases and are investigating five others.
