Hong Kong has confirmed its first case of swine flu, Chief Executive Donald Tsang Yam-kuen said.
''We have our first confirmed swine flu case in Hong Kong. He is Mexican,'' Tsang said.
The Mexican arrived yesterday via Shanghai from his home country, Tsang said.
The man checked into Metropark Hotel in Wan Chai before seeking treatment at Ruttonjee Hospital for flu symptoms. He developed a fever in the middle of the night after being warded.
Tests conducted by both the Department of Health and the University of Hong Kong found he was positive for swine flu.
He is in stable condition, Tsang said, at Princess Margaret Hospital, the designated facility for any swine flu, or H1N1, cases.
The hotel has been cordoned off.
''I will raise the alert level from serious to emergency,'' the chief executive said.
Despite putting the city on the highest level of alert, Tsang said all social activities and exhibitions will go ahead as normal and schools will remain open.
