After more than 300 cases of swine flu were confirmed in Australia, NSW health authorities need to decide whether to quarantine the 2,500 people on board the cruise ship Pacific Dawn in Sydney Harbour today. A child who had come into contact with a passenger was rushed to hospital last night with flu-like symptoms. Results from swab tests that have already been taken from passengers displaying symptoms will determine whether all 2,500 cruise passengers can disembark, otherwise a week-long quarantine period will apply. The number of confirmed cases in Australia rose to 303 at the weekend, with 212 of those in Victoria. Eleven Victorian schools have been closed to prevent the spread of the virus.
