An urgent e-mail appeal for donors of O-negative blood to save a cancer-stricken baby in Hong Kong appears to be a sick hoax. No request for such blood has been received, the Hong Kong Red Cross Blood Transfusion Service confirmed last night. 'We are the only organisation in Hong Kong responsible for blood products. If there is a need for special blood, we would co-ordinate its collection and distribution,' a spokeswoman said. Since no individual or hospital has contacted the service, it has concluded the e-mail is a hoax. The message, forwarded to thousands of people in Hong Kong in recent days, reads: 'Urgent: A baby in Hong Kong needs O-negative blood type to survive. A seven month old baby has cancer. He has lost one of his kidneys already and the other is fading away. His blood type is O-negative, which is rare in Hong Kong. O-positive doesn't work for the baby.' The rarity factor is correct. Only one in 370 Chinese has O-negative blood compared with one in seven Caucasians. 'If you know of someone who has O-negative blood type please call his father. Vincent Wong: 9735 8296,' the e-mail continues. But the transfusion service, like many others, found the mobile number disconnected when it tried to call. 'We have been unable to contact the baby's father according to the information in the e-mail,' said the spokeswoman. The transfusion service reassured the public there is no such blood shortage. 'The supply of O-negative blood is sufficient to meet the demand of all hospitals,' the spokeswoman said.
