China's Ministry of Health on Wednesday confirmed a man who returned from Canada last week has tested positive for the A/H1N1 influenza.

The case, the second of its kind on the Chinese mainland, involved a 19-year-old student surnamed Lv who arrived in Beijing from Canada on May 8 and traveled to Jinan, provincial capital of Shandong, three days later.

He is now "recovering with a normal body temperature," the health ministry said on its website.

The development came just two days after a 30-year-old man surnamed Bao was found to have contracted the virus in Chengdu, Sichuan Province. Bao is the first confirmed case of A/H1N1 on the Chinese mainland.

Lv, who studied at a Canadian university, boarded Air Canada flight AC029, which departed Toronto on May 7 and stopped in Vancouver before arriving in Beijing on May 8. A Health Ministry spokesman said Lv boarded the flight at noon on May 7, but he did not know at which Canadian city.

Airport authorities said his body temperature was normal when he arrived in Beijing.

He had a fever on May 10 and developed a sore throat and headache on May 11. He took his temperature himself, and had a reading of 39 degrees Celsius, according to the ministry.

Lv left Beijing by train D41 on Monday evening for Jinan, the provincial capital of Shandong, and reported by phone to the Jinan Center for Disease Control and Prevention (CDC) while on the train. He was later sent to the Jinan Infectious Disease Hospital for isolation and treatment.

The Jinan CDC and Shandong CDC conducted tests on the virus specimen of the patient Tuesday, which showed that he was "suspected positive" for A/H1N1.

The country's health authorities had begun to trace those in close contact with Lv during his travels.

Passengers from the 32nd to 38th row on flight AC029 on May 8, and those who traveled on the seventh carriage of Monday's train D41 were required to report to health authorities as soon as possible, said the statement.
