Progress in public-private partnerships to fight neglected diseases.

In the global fight against neglected tropical diseases (NTDs), public health partnerships involving donations of medicines by pharmaceutical companies are enabling access to treatment for millions of people worldwide. These partnerships collaborate with other disease programs and a range of key stakeholders to develop and improve programs to control and eliminate NTDs. Although progress is being made against NTDs, continued success depends on a policy environment that supports appropriate levels of engagement and collaboration from all participants.
