My sister Maureen McGinley, who has died aged 77, was a member of the Order of Columban Sisters, a progressive Irish Catholic order whose nuns train as doctors, nurses and teachers before going abroad.
While serving in Hong Kong, Maureen made a significant and pioneering contribution to the care of people who are HIV positive. In 1994 she founded the Society for Aids Care (SAC), the first non-governmental organisation of its kind in Asia. It continues its charitable work to this day. Maureen devoted her life to the welfare of the people of Hong Kong from 1976 until 1999.
