PCCW technician Lui Kwan-hang was examined by three doctors when he complained of feeling unwell - they all told him he had minor flu symptoms, prescribed medication and sent him home. But the 20-year-old later collapsed and was two weeks in a coma before dying, the Coroner's Court heard yesterday. Laboratory tests showed he had the H3N2 flu virus and staphylococcus aureus bacteria. Lui died on September 6 last year after fighting for his life in North District Hospital. Lui's father, Liu Tin-sing, told Coroner Michael Chan Pik-kiu that his son bought some over-the-counter drugs when he first showed minor symptoms. But he felt very unwell on August 10 and went to a flu clinic in Fanling, where he was given medication and returned home. When he felt unwell again, he went to North District Hospital's accident and emergency department on August 11 after midnight. He was given medicine and returned home. Both Dr Shum Man-wai of the flu clinic and Dr Siu Yuet-chung of the hospital's accident and emergency unit, who saw Lui, yesterday testified that Lui's body temperature was within a normal range and they did not find anything unusual. After the hospital visit, Lui went to a private doctor the following morning. Dr Ho Siu-fai, who saw Lui, said in court that Lui had flu symptoms and diarrhoea but was not critical. Ho prescribed only medicine. Lui's mother, Yu Man-ying, told the coroner that her son's condition became so bad that he collapsed at home in the afternoon, just hours after he saw Ho. He was admitted to hospital but his condition deteriorated so rapidly that he was transferred to the intensive care unit the same day. The hearing, set for three days, continues today.
