Global health is facing a critical moment. New scientific breakthroughs are making a huge difference in the fight against epidemics like HIV/AIDS, tuberculosis, and malaria. But funding is down and priorities are shifting. Will these diseases finally be eliminated? Or will they surge instead?

On The Threshold, reporters from around the world cover this unfolding crisis from all sides—talking to scientists, politicians, civil society leaders, pharmaceutical executives, and others. The Threshold is a new seven-part Foreign Policy podcast hosted by acclaimed broadcast journalist Henry Bonsu and made possible through funding in part from the Gates Foundation.
