Claudia Hammond reports on Covid-19 and "moral injury" - when the virus peaks, some healthcare staff will find themselves in a situation never faced before, forced to make decisions they would never normally have to make. This puts them at risk of a so-called “moral injury” which might harm their mental health. It’s more often associated with life in the armed services and Neil Greenberg, Professor of Defence Mental Health at Kings College London, explains how he's applying lessons from research in the military to support staff starting work at the new Nightingale Hospital in London. And some of the million recipients of letters saying they should shield themselves by not going out at all for 12 weeks are people who have asthma. Margaret McCartney examines the evidence for how those with asthma receiving letters were selected. Plus the latest dispatch from University Hospital Southampton: consultant Chris Hill explains that the emergency department has been split into Red and Blue areas based on the probability of arrivals having Covid-19. And what’s happening to mental health services during this time of crisis when seeing someone face-to-face needs to be avoided as much as possible? Claudia finds out from psychiatrist Dr Sri Kalidindi.
