Nearly a quarter of people in the United States are experiencing symptoms of depression, according to a study published Wednesday. That's nearly three times the number before the COVID-19 pandemic began. And those with a lower income, smaller savings and people severely affected by the pandemic — either through a job loss, for example, or by the death of a loved one — are more likely to be bearing the burden of these symptoms. The mental health toll of the coronavirus pandemic seems to be far greater than previous mass traumas. Traumas linked to pandemic have included ongoing anxiety and fear of catching the disease, and grief over the illness or loss of loved ones as well as the economic fallout.
