There’s a killer bug out there. The problem is we don't know what it is, where it is and when it will hit us. Are we ready for the next global pandemic? Old diseases believed to be eradicated are making a comeback. So who is working on spotting them, keeping them contained and stopping them spreading around the world? Roundtable is a discussion programme with an edge. Broadcast out of London and presented by David Foster, it's about bringing people to the table, listening to every opinion, and analysing every point of view. From fierce debate to reflective thinking, Roundtable discussions offer a different perspective on the issues that matter to you. Watch it every weekday at 15:30 GMT on TRT World.
