By a mother infected by a bisexual man or drug abuser

1. I don't think that's true -- unless some ridiculous percentage of the population of Southern Africa is bisexual.
2. Even if it were true, so what? Do women control who their husbands cheat on them with?

In the long run -- at least from the woman's perspective -- it really doesn't matter.
