Sally is a grandmother in her 50s. She has AIDS-related complex. There are 1,300 women in Britain who are known to be carrying the human immuno-deficiency virus, HIV. Up to ten times as many may be infected and still undiagnosed. Unlike Sally, many are in their 20s and 30s and they want children. But there's a 25 per cent chance that a positive mother will pass the virus on to her child. Is this a risk she's entitled to take? And what about the fact that she may not live to see her children grow up? Some of the women who have been caught in this tragic dilemma talk to Sarah Dunant about the choices they have made, and about what it means to be an HIV-positive woman.
