Three dead and British tourist in intensive care after suspected hantavirus outbreak on polar expedition ship

Three people, including an elderly couple, have died and five others have been taken unwell after a suspected virus outbreak on a cruise ship sailing in the Atlantic Ocean.

One case of hantavirus has been confirmed, while one British national, aged 69, is in intensive care in Johannesburg, South Africa.

The outbreak was reported aboard the MV Hondius cruise ship, which was travelling from Argentina to Cape Verde.

The MarineTraffic global shipping website identified the vessel as a Dutch-flagged passenger cruise ship. It was docked in Praia, the capital of Cape Verde, on Sunday night.

The local authorities were assisting but had not allowed anyone to disembark. It said the two sick people onboard requiring urgent medical care were crew members.

South African authorities told the BBC the first person to show virus symptoms was a 70-year-old passenger who died on board. His body is now on the island of Saint Helena, a British territory in the South Atlantic.

His 69-year-old wife also became ill on board and was evacuated to South Africa, where she died in a Johannesburg hospital.

The World Health Organisation said that it was working with authorities to evacuate two other passengers with symptoms from the ship.

Hantaviruses, which are found throughout the world, are a family of viruses, typically linked to exposure to the faeces or urine of infected rodents, the World Health Organisation (WHO) said.

While rare, WHO said they can be spread between people and they can lead to severe respiratory illness.

Hantaviruses cause two serious syndromes, according to the US Centers for Disease Control and Prevention: hantavirus pulmonary syndrome, a severe disease that effects the lungs, and hemorrhagic fever with renal syndrome, a severe disease that affects the kidneys.

There is no specific treatment or cure, but early medical attention can increase the chance of survival.

In a statement, they said: "WHO is aware of and supporting a public health event involving a cruise vessel sailing in the Atlantic Ocean. To date, one case of hantavirus infection has been laboratory confirmed, and there are five additional suspected cases. Of the six affected individuals, three have died and one is currently in intensive care in South Africa.

"Detailed investigations are ongoing, including further laboratory testing, and epidemiological investigations. Medical care and support are being provided to passengers and crew. Sequencing of the virus is also ongoing.

"Hantavirus infections are typically linked to environmental exposure (exposure to infected rodents’ urine or faeces). While rare, hantavirus may spread between people, and can lead to severe respiratory illness and requires careful patient monitoring, support and response.”

Hantavirus was in the news after the late actor Gene Hackman's wife, Betsy Arakawa, died from hantavirus infection in New Mexico last year. Hackman, who had Alzheimer’s, died a week later at their home.

The MV Hondius is run by tour company Oceanwide Expeditions, described as the “first-registered Polar Class 6 vessel in the world, meeting the latest and highest Lloyd’s Register standards for ice-strengthened cruise ships”.

A Foreign Office spokesperson said: "We are closely monitoring reports of a potential hantavirus outbreak on the cruise ship Hondius and stand ready to support British nationals if needed. We are in touch with the cruise company and local authorities."

The Independent has contacted Oceanwide Expeditions for comment.

The company that runs the cruise, earlier told the Associated Press, the third victim's body was still onboard the ship in Cape Verde and its priority was to ensure the two crew members who were ill received medical care.

"Local health authorities have visited the vessel to assess the condition of the two symptomatic individuals," the company said. "They are yet to make a decision regarding the transfer of these individuals into medical care in Cape Verde."

South Africa's Department of Health said the ship, the Dutch-flagged MV Hondius, had left Argentina around three weeks ago for a cruise that included visits to Antarctica, the Falkland Islands and other stops. It was due to ultimately head to Spain's Canary Islands on the other side of the Atlantic.

Around 150 tourists were onboard at the time of the outbreak, South Africa's health department said. Several online tour operators said the Hondius, which is described as a specialist polar cruise ship, usually travels with around 70 crew members.

WHO said it was working with national authorities and the ship's operators to conduct a "full public health risk assessment" and provide support for those still onboard.

South Africa's National Institute for Communicable Diseases, meanwhile, was conducting contact tracing in the Johannesburg region to identify if other people were exposed to the infected passengers in South Africa.
