US virus cases top 1 million

Known cases of the coronavirus in the U.S. topped 1 million — about a third of global cases — as some governors began reopening businesses and the White House issued guidance on testing to help counter the contagion. While closures and stay-at-home orders have sent the jobless rate soaring in recent weeks, prompting a push to restart economies, health experts warn that testing capacity is insufficient to guard against a new wave of infections.
