Even as President Donald Trump urges getting people back to work and reopening the economy, thousands of new coronavirus infections are being reported daily, many of them job-related. Recent figures show a surge of cases in meat-packing and poultry-processing plants. There’s been a spike of new infections among construction workers in Austin, Texas, where that sector recently returned to work. Even the White House has proven vulnerable, with positive coronavirus tests for one of Trump’s valets and for Vice President Mike Pence’s press secretary.
