“Contact tracing for passengers on the flight has been initiated,” the WHO said.
Airlink operates one flight a week from the island, which takes around four hours and 45 minutes.
The South African authorities had asked the airline to notify the passengers that they must contact the Health Department, a representative, Karin Murray, told AFP.
The WHO said it suspected that hantavirus may have spread between people on the cruise ship, which today NZT was anchored just off Cape Verde.
Besides the Dutch couple, a German passenger has also died. There are two confirmed and five suspected cases.
Saint Helena, home to around 4400 close-knit people, said passengers from the MV Hondius had come ashore and some people on the remote South Atlantic island were being asked to isolate themselves.
“Two passengers with minor symptoms came ashore and may have had some contact with members of our local community,” the British overseas territory’s Government said in a statement.
“While the virus can be serious, no cases of this illness have been identified in St Helena and there is no significant cause for concern on the island at this time.
“A small number of people who travelled to St Helena on the MV Hondius or had very close contact with those who were showing symptoms, are being advised by Public Health to undertake a period of self-isolation as a precaution.”
The Government said a full risk-based contact tracing process was underway to identify and notify such persons.
