Zambia: HIV behind bars

International AIDS Conferences—like the one planned for next week in Vienna—can be strange affairs. On the one hand, there is a reason to celebrate: Scaled up treatment campaigns have prolonged millions of lives; HIV testing and education are reaching many more. Yet, on the other hand, there is the reality that more than 33 million people are living with HIV worldwide. Despite efforts to expand treatment, nearly three million more become infected each year. In Zambia alone, over one million people are living with HIV.
