Nearly 3.2 million laid-off workers applied for unemployment benefits last week as the business shutdowns caused by the viral outbreak deepened the worst U.S. economic catastrophe in decades.

Roughly 33.5 million people have now filed for jobless aid in the seven weeks since the coronavirus began forcing millions of companies to close their doors and slash their workforces. That is the equivalent of one in five Americans who had been employed back in February, when the unemployment rate had reached a 50-year low of just 3.5%.
