On this new season of Prognosis, we look at the spread of infections that are resistant to antimicrobial medicines. You're probably more likely to have heard of these as superbugs. Their rise has been described as a silent tsunami of catastrophic proportions. We travel to countries on the frontline of the crisis, and explore how hospitals and doctors around the world are fighting back. Prognosis’ new season launches Sept. 5.See omnystudio.com/listener for privacy information.
