James Gallagher, BBC health and science correspondent, and Dr Margaret McCartney talk about the new coronavirus and how GPs have been advised to manage a patient at risk. He meets listeners Rich and Lucy who have asked about probiotics and gut health in early life after one of their twins had a vaginal delivery while the other a C-section. They want to know whether the different types of birth might impact on the good bacteria passed from mother to child. What is the evidence for the potential impact on long term health and can probiotics help? Dr Trevor Lawley at the Sanger Centre and Dr Lindsay Hall of the Quadram Institute provide the answers. Debi Bhattacharya of the University of East Anglia and James discuss pill organisers and whether arranging medicines into one single packet is always a good idea. And Prof John Pasi explains the results of trials on a 'Holy Grail' treatment for Haemophilia A and Shaun, who took part in the trial at Guy's and St Thomas in London, reveals how it has changed his life.
