OS conversations: Olympic gold medallists

As the Olympic Games comes to an end we'll look back at the events of the past two weeks. We'll speak to our correspondents in Tokyo to hear what it's been like reporting from an Olympics during a pandemic. We'll also speak to some of the athletes who have won gold at the Games to hear their experiences.

Also, we're continuing to go to countries around the world that we haven't heard much from during the pandemic. Today we'll look at the biggest news stories from the South American country of Guyana. Alongside Covid, they have also been dealing with flooding. We'll speak to a newspaper journalist there to hear more.

And every day we are joined by a health expert to answer listener questions about Covid-19 and the vaccines. Today our guest is Dr Megan Murray - Professor of Global Health and Social Medicine at Harvard University.
