The biggest public health challenge is rebuilding health systems. In other words if you look at cholera or maternal mortality or tuberculosis in Haiti they're major problems in Haiti but the biggest problem is rebuilding systems.

We've taken on the major health problems of the poorest - tuberculosis maternal mortality AIDS malaria - in four countries. We've scored some victories in the sense that we've cured or treated thousands and changed the discourse about what is possible.

We don't have enough support for maternal leave and the kinds of things that some of the European countries do. So we still make it hard on women to go into the work force and feel that they can be good at work but then doing the most important job which is raising your children in a responsible and positive way.

You cannot have maternal health without reproductive health. And reproductive health includes contraception and family planning and access to legal safe abortion.
