National Institute for Communicable Diseases (NICD) was informed of a cluster of passengers with an undiagnosed sudden acute respiratory infection aboard an international cruise ship (MV Hondius) travelling from Southern Argentina to Canary Islands via Cape Verde.
While the ship was travelling past South African shores, some of the passengers experienced serious health complications arising from what was initially considered severe acute respiratory infections.
The ship, carrying about 147 individuals (88 passengers from various countries, and 59 crew members) had departed Ushuaia, Southern Argentina, for Canary Islands on 1 Apr 2026. Enroute to its destination, the ship went past several islands, including mainland Antarctica, Falklands, South Georgia, Nightingale Island, Tristan, St Helena, and Ascension
In terms of medical cases, the first patient was a 70-year-old male passenger who suddenly became ill in the ship enroute from Ushuaia to St Helena Island, and presented with fever, headache, abdominal pain, and diarrhoea. Unfortunately, he passed away on arrival at St Helena Island. His mortal remains are in St Helena, awaiting repatriation to the Netherlands.
The second affected passenger was a 69-year-old female, the spouse to the first patient, who collapsed at the OR Tambo International Airport while trying to connect a flight to her home country of the Netherlands. She was taken to a nearby health facility around Kempton Park for medical attention and unfortunately passed away. Her laboratory test result was positive for Hantavirus.
The third patient, a British national, also became ill while the ship was travelling from St Helena to Ascension. Despite medical treatment provided to him at Ascension, his condition did not improve and necessitated his medical evacuation to a South African private health facility in Sandton for further medical management. His laboratory test results came back positive for Hantavirus – a rare but potentially deadly virus transmitted primarily by rodents. The patient is still in critical condition in isolation, but receiving medical attention.
The Department is working with the NICD and Gauteng Health Department authorities to conduct contact tracing to stop potential spread of the virus by identifying and monitoring individuals who may have been exposed to the infected persons.
In our view, there is no need for the public to panic because only two patients from the cruise ship have been within our borders. The World Health Organization is coordinating a multi-country response with all affected islands and countries to contain further spread of the disease.
