Four cruise ship passengers tested amid a swine flu scare on arrival in Sydney yesterday have been cleared of infection.
The suspected cases were among 2,000 passengers and 900 crew who were quarantined for more than five hours aboard the 77,000 ton luxury liner Dawn Princess.
A spokeswoman for NSW Health said all four tested negative for influenza-A and there was no need for additional testing for swine flu.
They had all shown mild flu-like symptoms and were asked to remain in Sydney and stay away from other people until the test results were confirmed.
The spokeswoman said late on Saturday the four had been allowed to resume their travel plans.
The Dawn Princess arrived at Darling Harbour about noon (AEST) on Saturday, hours late due to severe weather along Australia's east coast for the past week.
To make matters worse, health officials were called out and the ship was locked down before the passengers could disembark and the same number of cruise passengers could board the ship for their ocean holiday.
