In the States, the HIV transmission from mother to child is almost completely preventable - the only mothers who really do transmit it are the ones who don't come in for care.

You're not going there just to merely observe. You have a purpose, and your purpose is to tell that story, to share that story for the bigger benefit of millions of other people. Your purpose is to create that bridge so you can give that story the dignity and the focus that it deserves, and you can become a part of the amplification that needs to be there.
