In China, authorities said a student who had recently returned from Canada and then took a train to the eastern province of Shandong had tested positive for the Swine Flu virus. They immediately started trying to track down anyone who may have had contact with the 19-year-old, even as the search continued for passengers who were on the same flight as mainland China’s first confirmed swine flu case.

Meanwhile, in Hong Kong, authorities said a 24 year old man, who had returned from the United States, was confirmed with swine flu, and he’s being held in isolation in hospital.
