The family of a Vietnamese boy who kept a vigil outside a camp clinic for two days and nights to try and get urgent medical treatment for their son plan to sue the Government for negligence. The eight-year-old boy, Chau Vinh Son, is on kidney dialysis at Queen Elizabeth Hospital after suffering renal failure. His parents claim he was denied access to the camp clinic at Whitehead for five days. He had previously been hospitalised with kidney problems and needed urgent medication from doctors. In desperation, the parents kept a vigil with their son outside the clinic for two days and nights in the September heat. 'All they could do was to stay there,' Refugee Concern lawyer Peter Barnes said. The boy had recently been discharged from Queen Elizabeth Hospital and required medication for his condition. When his condition began to deteriorate, his parents took him to the clinic. But he was refused access for five days, Mr Barnes said, even though each day it was obvious his condition was worsening. When the boy was eventually rushed to hospital, 'doctors advised his parents if he hadn't been brought to hospital and had stayed in the camp for a matter of hours, he would have died'. The child has subsequently been on kidney dialysis since the incident at the beginning of October last year. 'This is a negligence action, or at least action against the Government for failure to take due care of someone in their custody,' Mr Barnes said. Refugee Concern has applied for Legal Aid on behalf of the family. The refused access 'could be due to anything', he said. 'I suspect it was in part due to restructuring, the fact there were new people at Whitehead,' he said. Another family last week said it would sue the Hospital Authority after Tsan Bac Sang, 45, died after being released from the Prince of Wales Hospital.
