James Gallagher discusses the risk from H5N1 bird flu in the UK as a poultry worker in the West Midlands is infected and looks to the US where the disease is spreading in cattle. He's joined by virologist Dr Ed Hutchinson from the University of Glasgow to discuss how the virus is evolving, whether we are edging closer to bird flu becoming a pandemic and how it's being handled in the US as President Trump's government takes office.Also, you've been sending in your questions on embarrassing health problems and lots of you have asked about the problem of leaking urine, known as urinary incontinence. James puts your questions to Dr Vanessa Apea, a consultant physician in Genito-urinary and HIV medicine at Barts Health NHS Trust and an Honorary Senior Lecturer at Queen Mary University of London.Presenter: James Gallagher Producer: Tom Bonnett
