Science In Action

After last year’s first wave of covid-19 in the UK, individuals who had been discharged after hospitalisation suffered higher rates of coronary and respiratory disorders, and even diabetes subsequently over 140 days. As Dr Ami Banerjee of University College London explains, out of 48,000 cases, patients who had had acute covid-19 were four times more likely to be readmitted and 8 times more likely to die. Ami’s team suggests in their paper published in the British Medical Journal that diagnosis, treatment and prevention of post-covid syndrome needs an integrated approach.In France, researcher Xavier Montagutelli describes how his team has observed that unlike the original virus, some of the newer Variants of Concern can infect mice in laboratories. They do not show serious illness, but nevertheless host the virus in their lungs. Whilst infection is unlikely in natural environments and not yet observed in the wild, it does show how the viral variants can extend the host range, perhaps leading to more opportuni
