A group of Southern Oregon students on an educational trip to China has been further delayed there by a swine flu quarantine. Kristian Foden-Vencil has more.

Sixty-five students from St. Mary's School in Medford were put in quarantine last week after one tested positive for swine flu.

Now 12 more have tested positive and are being held in a hospital until they test negative -- maybe in four days.

School principal, Frank Phillips, says Chinese officials have done a good job of stopping the virus spreading through their population, but....

Frank Phillips:"It's been incredibly disappointing and the Chinese reaction has been very aggressive. Our students were quarantined for a week in Beijing before they were re-quarantined with a number of students form other schools and there was some mingling and fraternization. And I think the quarantine may have infected our kids actually."

Phillips says the students who swabbed positive are showing only mild symptoms, like headaches, but none of them is very ill. Most of the students are expected back in Oregon on Friday.
