Hong Kong - Five patients were in isolation Wednesday in a Hong Kong hospital, suffering from a mystery respiratory disease, government-run radio said. The five patients were transferred from the city's Castle Peak Hospital, where they fell ill, to an isolation unit at Tuen Mun Hospital, where they were undergoing further tests Wednesday.
All five patients tested negative for influenza A and B, a hospital spokesman told the government-run radio station RTHK.
Hong Kong has been on alert over cases of respiratory illness since 2003 when an outbreak of severe acute respiratory syndrome, or SARS, killed 299 people and infected 1,755 after spreading to the former British colony from China.
