The Chinese mainland has reported its first confirmed infection of A/H1N1 Influenza. The case was found in Chengdu, capital of southwestern Sichuan province. Emergency measures are already in place.

Officials in Sichuan say the patient is a 30-year-old man. His condition is stable. Basic vital signs are normal.

The man is a native of Sichuan studying at a university in the US state of Missouri. On Thursday, flew from St. Louis to Tokyo. On Friday, he took flight NW029 from Tokyo and arrived at the Beijing International Airport early on Saturday. The same day, on flight 3U8882 to Chendgu, he developed a fever and other symptoms. He was met by his father and girlfriend, and the three took a taxi to hospital.

Authorities in Sichuan are stepping up efforts to locate everyone who's had close contact with the man.

More than 130 of 150 passengers on the flight to Chengdu 3U8882 are under quarantine. Nearly 30 of 144 passengers on the flight from Tokyo are now under observation.

The Chinese Ministry of Health has dispatched a team of experts to Chengdu to guide prevention and control.

It's also asked local health authorities to immediately send a virus specimen to the Chinese Center for Disease Control and Prevention for a second check.
