Il Nuovo Postiglione - Passenger from hantavirus cruise quarantines on remote Pitcairn Island

The woman, a US citizen, journeyed halfway across the globe to reach remote Pitcairn Island after disembarking the cruise ship in Saint Helena, authorities said.

"We can confirm that someone who had contact with a hantavirus-exposed individual is currently isolating on Pitcairn Island, showing no signs of illness," said a Pitcairn government spokesman.

"We are working closely with the health authorities and the UK Government to manage the situation. The wellbeing of our community remains the top priority."

It was not clear how long the woman might be stuck on Pitcairn Island or how she will be isolated from the around 50 people who call the British territory home.

Pitcairn Islanders contacted by AFP said they had been advised against speaking with journalists and should pass all questions on to government officials.

It was no small effort for the jet-setting American to reach Pitcairn Island, which bills itself as a "must see for adventurous travellers seeking truly remote horizons".

She first flew from San Francisco to Tahiti and then onwards to the isle of Mangareva in outer French Polynesia.

From Mangareva most tourists reach Pitcairn by hitching a 32-hour ride on one of the cargo ships that shuttle back and forth every few days.

The government of French Polynesia said she had done all this without telling authorities of her possible exposure to hantavirus.

She will not be allowed to leave the island as long as she "poses a risk to others", the government said in a statement earlier this week.

The UK government -- which counts Pitcairn as an overseas territory -- said the woman was not symptomatic, but it was still taking a "precautionary approach".

There is only one grocery store on Pitcairn Island, which typically opens three times a week.

The nearest hospitals are in French Polynesia, some 1,350 miles (2,170 kilometres) to the northwest, or New Zealand, about 5,300 kilometres (3,300 miles) southwest.

Three people died after the rare rat-borne hantavirus spread through passengers holidaying on the MV Hondius cruise ship, sparking a global health scare.

Health authorities have repeatedly emphasised that the broader risk to public health from the outbreak of the Andes strain of hantavirus -- the only one known to spread between people -- is low.

Globally, the death toll remains at three.

No vaccines or specific treatments exist, but health officials have said the risk is low and have dismissed comparisons to the Covid-19 pandemic.

The Pitcairn Islands were colonised in 1790 by the mutinous crew of the Royal Navy ship HMS Bounty, led by the master's mate Fletcher Christian.

Their actions, casting adrift the ship's captain William Bligh, have been immortalised in books and film.

Pitcairn's people are descended from the mutineers and their Tahitian companions.
