The quarantined, including 13 flight crew, 28 Mexican and 28 Chinese passengers, were all quarantined separately, except for a Mexican couple on honeymoon, Chen said.

Two doctors, three nurses and some other medical workers had been sent to the hotel, Chen told Xinhua on Monday afternoon.

All the quarantined receive medical examinations twice a day. They can contact people outside, watch television, listen to music, read books or surf the Internet, she said.

In Liaoning Province in northeast China, a further two people who had taken the same flight, Thursday's Aeromexico 098 from Mexico City to Shanghai, with the Mexican patient, had been quarantined "with good living conditions," said Wang Tianyu, assistant director of Liaoning Provincial Health Department. In addition, five of their family members had also been quarantined.

The two are colleagues and were sent to Mexico on April 16 by their company on business, Wang said.

"A nutritious and delicious diet had been offered for them every day," Wang said.

None of the passengers quarantined had shown flu symptoms as of Sunday noon, China's health ministry said.

There were 176 people and 13 crew members on the flight. Of these 56 disembarked in Shanghai, 41 caught a connecting flight to Guangzhou, 17 transferred to Beijing, and two were refused entry to China. That accounts for 116 of the passengers, some of whom --including the Mexican male -- flew on to Hong Kong, taking China Eastern Airlines flight MU505.

The Mexican was put into quarantine in the Metropark Hotel, in Hong Kong, said the Special Administrative Region's Health Department.

All those quarantined were quarantined on the orders of China's Health Ministry.
