A suspected hantavirus outbreak on a cruise ship in the Atlantic Ocean killed three people, including an elderly married couple, and sickened at least three others, the World Health Organization and South Africa’s Department of Health said Sunday.
The World Health Organization said at least one case had been confirmed and an investigation was ongoing. One patient was in intensive care at a hospital in Johannesburg, and the agency said it was working with authorities to evacuate two others with symptoms from the ship.
Oceanwide Expeditions, the Dutch company operating the Dutch-flagged MV Hondius, said the ship was off Cape Verde and local authorities had not allowed anyone to disembark.
Hantaviruses are mainly spread through contact with the urine or feces of infected rodents, according to the Centers for Disease Control and Prevention. The viruses can cause severe lung or kidney disease. The WHO said person-to-person spread can occur in rare cases and that there is no specific treatment, though early medical care can improve the chance of survival.
South Africa’s health department said the ship left Argentina about three weeks ago on a cruise that included Antarctica, the Falkland Islands, and other stops. It was due to head to Spain’s Canary Islands.
The department said the first victim, a 70-year-old man, died on the ship and his body was removed in the British territory of St. Helena. His wife later collapsed at an airport in South Africa while trying to take a flight to the Netherlands and died at a nearby hospital.
The patient in intensive care was a British national who became ill near Ascension Island after the ship left St. Helena and was transferred to South Africa, the department said.
Around 150 tourists were onboard at the time of the outbreak, according to South Africa’s health department.
