Let me first clarify, this has nothing to do with mother to baby transmission...
It's about Ntando, who may be infected with HIV after sleeping with his girlfriend, Sylvia, who slept with Ntando's HIV+ father.
It sounds mind boggling... It sounds as though it was taken out of a science fiction. The sad news is that, it is no tale but our reality. As Intersexions highlights that you don't know your partner's sexual partners, it's possible that you and your mother or you and your father might sleep with one person (without knowing).
Here is what happened on Intersexions:
Ntando has reconciled with his estranged father, a disgraced former teacher who has full-blown AIDS. Ntando is also in love with Sylvia, a young single mother. Ntando's father impregnated Sylvia whilst she was his music student. A while later Sylvia is a mother to Ntando's father's baby. Ntando sleeps with Sylvia unaware of this. The father comes clean to Ntando and he's devastated by the confession.
It may sound absurd, but how sure are you that you and your parent don't share or have shared a sexual partner? Would you have the guts to ask your parent about their sexual partners?
What would you do if you found out your parent, through sharing the same sexual partner, gave you HIV?
How would you react to the news that your partner's baby is your brother or sister?
