Lift lockdowns 'when we know that we've got the defence mechanisms'

By late March we learnt hygiene, keeping our distance from one another and isolating with symptoms were the primary tools for combating the spread of coronavirus. Now - as part of normal life starts to resume alongside the imperative of preventing a second peak - we have a wider pool of data and analysis to inform and influence policy. We know from NHS figures that a quarter of patients who've died in hospitals in England with the virus had diabetes. We also have data that shows a regional breakdown in the infection rate - with the R or reproduction number of the virus down to 0.4 in London but at 0.83 in the North East and Yorkshire. How does this information inform the next steps countries should take? (Image: David Nabarro. Credit: Reuters)
