Berlin high school shuts after 8 students test positive for swine flu

Berlin: Authorities say a Berlin high school has been shut down after eight pupils tested positive for the swine flu, including three American exchange students.

Berlin health authorities said Monday all eight of the students have only a mild case of the flu and are being treated while under quarantine at their homes.

In the meantime the Alexander von Humboldt high school will be closed while other students are tested to see if they are also infected.

The Berlin health department says the exchange students have been in Germany several weeks and it's unclear whether they picked up the virus here or in the United States.
