For many, the pandemic is merely an annoyance. But some groups face a particular risk of post-traumatic stress disorder (ptsd), the symptoms of which include nightmares, flashbacks and feelings of guilt, anxiety or isolation. The most vulnerable are those who have been very ill, or lost relatives, as well as victims of previous traumas (such as refugees), and those with front-line jobs, such as doctors and nurses. In Spain nearly a sixth of those infected are health-care workers, and most of them show signs of ptsd. In Bangladesh, where the incomes of poor people briefly fell by 80% when lockdowns were tight, 86% of people in one poll reported covid-19-related stress.
