A CORONER'S jury yesterday returned a verdict of death by natural causes on a 29-year-old illegal immigrant who had the AIDS virus. Wong Man died from pneumonia on August 29, five days after being admitted to Queen Elizabeth Hospital. Medical officer Dr Lao Wai-cheung, who certified Wong dead on August 29, told the jury and Coroner Richard Venning that the woman attended the accident and emergency unit on August 24. She had a high fever, her pulse rate and breathing were fast and she was dehydrated and emaciated. Wong was diagnosed as suffering from pneumonia and placed on antibiotics. A blood test showed she was HIV-positive. Her condition deteriorated and Wong was placed on different antibiotics, but failed to respond. On August 29 attempts to resuscitate her failed and she was pronounced dead. The clinical cause of death was pneumonia. Dr Lao confirmed that Wong could have probably recovered from pneumonia had her immune system been normal. The court heard that, shortly after being admitted to the hospital, Wong was arrested as an illegal immigrant. She was handcuffed to her bed and placed under police guard. Police constable Ma Chung-wah, who was sent to the hospital, said Wong initially gave her name as Chan Shui-sum. But the hospital record card revealed that her real name was Wong Man. Her husband, Yip Shing-fat, was also arrested for allegedly aiding and abetting his wife to remain in Hongkong, but police decided not to prosecute him after it was confirmed the couple had married in China. The court was told that Wong first learned she was HIV-positive in January last year. She had asked for a blood test, concerned about the effects of a blood transfusion received in China. She did not tell her husband and did not take her doctor's advice to seek hospital treatment. The reason she gave was that she preferred traditional herbal medicine. Dr Leung Kim-pong, who examined her in his Kowloon clinic, told the court that Wong remained relatively healthy, although she had persistent oral infections, until July last year. She then developed a low-grade fever and suffered dramatic weight loss. Mr Yip denied he had told doctors his wife had been promiscuous before she married him, saying he had only revealed just before her death that she had been ''a bit active''. He confirmed she had a blood transfusion in a Shenzhen hospital in 1990, but said he could not say whether that was how she had contracted AIDS. Asked whether there was any other possible cause, he said he suspected ''some relationship with one of her former boyfriends'' might have been to blame.
