Beijing last night confirmed two new cases of swine flu, bringing the number of A/H1N1 infections on the mainland to seven. Taiwan also confirmed two new cases yesterday, bringing the total number on the island to five. One of the mainland's latest cases was a 69-year-old man, identified only with his family name Zhang, who took flight AC031 on Saturday with his wife from Toronto, according to Beijing's Health Bureau. Mr Zhang developed a fever of 37.7 degrees Celsius with muscle pain on Thursday and was quarantined and treated at 302 Military Hospital. A test yesterday confirmed he had the H1N1 virus. His temperature had returned to normal and his vital signs were stable, the bureau said. Four people who had been in close contact with him were under medical observation and none had shown any flu symptoms. Just two hours after Mr Zhang's case was announced, the bureau said a 65-year-old American-Chinese man who flew from New York on Air China flight CA982 on Thursday had also tested positive. The man, surnamed Li, was detected with a fever of 37.5 degrees Celsius at the airport and was being quarantined and treated at Ditan Hospital. His condition was stable and his body temperature had returned to normal, the bureau said. Meanwhile, the health of the second confirmed case, a 21-year-old Chinese-Canadian man surnamed Yang, was improving. Two other H1N1 patients were discharged from hospitals in Beijing and Guangzhou yesterday after a week of treatment, Xinhua reported. Liu Xinwen, 18, who was diagnosed with the flu after returning from the US, was the first known H1N1 case in Beijing. Wearing a red T-shirt and blue mask and accompanied by her father, Ms Liu met the press before she left the hospital at 10am. The other patient, surnamed Yang, made a low-key departure from Guangzhou's No 8 People's Hospital very early in the morning, hospital president Yang Zhan said. Taiwan's two latest cases included a woman, 30, who flew in from the Philippines and had been to many places after she arrived on the island. The other case was the sister of a student who was Taiwan's third confirmed case. Both took a flight from the US on May 20.
