A total of 63 passengers entering China showed fever or other flu-like symptoms from Sunday to Monday, said the General Administration of Quality Supervision, Inspection and Quarantine on Tuesday.

Their cases have been handed to local health departments for further observation or treatment, the ministry said.

A total of 618 passengers entering China have been found to have fever or other flu-like symptoms among 5.61 million passengers screened when entering China from April 25 to May 11, the ministry said.

The ministry has been quarantining planes, ships, trains, automobiles and other vehicles from the countries affected by outbreaks of A/H1N1 flu.

Passengers entering China have been required to fill out health declaration forms so that they could be effectively traced if any A/H1N1 flu cases were found among them.

A Chinese mainland male surnamed Bao, who recently returned from the United States, tested positive for A/H1N1 influenza, the first such case reported on the Chinese mainland, the Ministry of Health (MOH) said on Monday.

A suspected case of A/H1N1 influenza was reported in eastern China's Shandong Province, the MOH said on Tuesday evening.
