Chinese health authorities on Thursday started lifting a seven-day quarantine on passengers from the Mexico City-Shanghai flight AM098, where a Mexican man was confirmed to be infected with influenza A/H1N1 on May 1.

The Ministry of Health on Wednesday notified local health authorities that the passengers quarantined in the Chinese mainland who took the same flight with the Mexican will be out of quarantine on Thursday, if they display no flu-like symptoms.

Also on Wednesday, 25 Canadian students were released from medical surveillance in Changchun, capital of northeast China's Jilin Province.

The overseas students at Northeast Normal University were put under observation at a hotel immediately after flying to Changchun on May 2 from Canada via Beijing.

The students had displayed no influenza A/H1N1-like symptoms, including fever and sore throat, local health authorities said late Wednesday.
