Thirty-five students and teachers of a US tour group who were quarantined in a central China city after seven of the 42-member group were diagnosed with A/H1N1 flu were released on Thursday afternoon and flew to Shanghai.

One of the seven flu patients has been discharged from hospital while six others were still under treatment in Yichang, Hubei Province, the city's flu control headquarters told Xinhua.
