A CHRISTMAS party held for HIV-infected haemophiliacs went sour when T-shirts bearing the word ''AIDS'', in English and Chinese, were given away as presents. Some families of the infected haemophiliacs, who have lived a life of secrecy, took the T-shirts home but said they would never wear them. An AIDS worker said: ''They were upset. This is a group of sensitive people. I felt it was mishandled . . . if you have lived a life of secrecy, it is not the kind of thing you expect.'' The long-sleeved, yellow T-shirts were printed for this year's Hong Kong AIDS week and sponsored by the Council for the AIDS Trust Fund. The T-shirts bear a heart-shaped pattern with the slogan ''Time to act. Hong Kong AIDS Week 1993'' printed on them. Mike Sinclair, education officer of the AIDS Foundation, distributed the presents dressed as Santa Claus at the December 19 party. A parent said: ''I appreciate the effort but I am not happy about the present. I know I should be thankful they held a party for us. But the T-shirt spoilt it. We won't even wear it at home because when we hang it out to dry, neighbours will see it.'' Another parent said: ''Maybe volunteers of AIDS agencies can wear them at functions. I am surprised they actually thought we would use them.'' She said the harsh fact was that AIDS sufferers were still being discriminated against. ''We don't want to hide but we have no choice. Fathers would lose jobs and families would lose friends. It is a sad situation. I hope those who work with HIV-infected patients will understand our difficulties,'' said the parent. Samson Chan, service programme officer of the AIDS Foundation, admitted they had not considered the sensitivity of the issue at the time, but he added the foundation had a budgetary constraint. ''It was the second time we held a Christmas party for them, but unlike last year, we had a smaller budget this time. We could not buy presents from outside.'' he said. None of the HIV-infected haemophiliacs who have joined the Sunday Morning Post campaign to win compensation have allowed themselves to be identified by name. Payments of about $28 million have so far been made to the 50 haemophiliacs infected with HIV through contaminated blood products. The Council for the AIDS Trust Fund - launched in April to advise the Government on how to spend $350 million on AIDS-related programmes - has also approved a further $1 million to fund projects related to publicity and public education on the killer disease. The council has put aside $100 million for the compensation scheme. An additional four haemophiliacs or their families have also applied for the ex gratia payments of up to $1 million each, and the council is expected to approve these in a January meeting. According to Tony Dickinson, Assistant Secretary for Health and Welfare, with the payments largely out of the way, the council was expected to turn its attention to longer-term projects.
