China confirmed its first mainland human case of A H1N1 influenza, China's Ministry of Health announced Monday, May 11.
The patient, a 30-year-old man surnamed Bao, is under treatment in Sichuan Provincial People's Hospital, according to the ministry. Meanwhile, his condition is stable, authorities reported.
Most of the passengers who flew with the patient to Chengdu have been quarantined by local health authorities, officials said.
Bao flew from St Louis in the United States on Friday and landed in Chengdu on Saturday, with transfers in Tokyo and Beijing.
After arriving in Chengdu, Bao showed flu symptoms and was tested positive for the H1N1 virus during two rounds of tests on May 10.
In addition, Chinese authorities quarantined seven people, including an American, who flew on flight NW025 from Canada on May 8, after four Japanese passengers in the same flight tested positive for the H1N1 virus.
In order to avoid a disease outbreak, China expanded its Tamiflu reserves, a medicine for flu prevention and flu treatment, Chen Zhu, minister of China’s Ministry of Health, told the press on April 30.
So far, three cases of A H1N1 influenza were found in Taiwan and Hong Kong.
As of May 10, the World Health Organization reported 4,379 cases in 29 countries.
