MELBOURNE, Australia (AP) — Six passengers from a cruise ship hit by a hantavirus outbreak arrived Friday in Australia for a quarantine expected to last at least three weeks.

The Gulfstream long-range business jet carrying them from the Netherlands landed at RAAF Base Pearce outside the Western Australia state capital, Perth. The passengers, crew and a doctor who accompanied them were taken by bus to the nearby Bullsbrook quarantine facility.

Australian Health Minister Mark Butler said the government would implement one of world's strongest quarantine responses to the outbreak.

He said passengers of the cruise ship MV Hondius who returned to the United States and most European countries would spend a few days in a quarantine center before they were sent home.

"We have taken the decision to take a stronger approach to quarantine arrangements than that because we are determined to ensure there is no risk at all of any transmission of this virus into the Australian community," Butler told reporters in his hometown of Adelaide.

The five Australians and one New Zealand citizen will spend the three-week quarantine period in the facility that had remained largely unused since it was built in 2022 is response to the COVID-19 pandemic.

A decision had yet to be made on what precautions should be taken for the remainder of the 42-day period of potential incubation that the World Health Organization had identified, Butler said.

The six passengers all tested negative for the virus before they left the Netherlands, had been assessed by a doctor during the flight and would undergo more detailed health assessments at Bullsbrook, Butler said.

The MV Hondius ship was on a cruise from Argentina to the Antarctic and then to several isolated islands in the South Atlantic Ocean when the hantavirus outbreak was identified. Three people among the 11 cases from the ship have died.

With the evacuation of all passengers and many crew members completed, the MV Hondius is now sailing back to the Netherlands, where it will be cleaned and disinfected.
