WASHINGTON - The death toll and economic devastation from the novel coronavirus reached staggering new levels in the United States on Thursday as officials reported more than 1,000 deaths from the pandemic in a single day and revealed that more than 6.6 million Americans had sought unemployment benefits in a single week.

Coronavirus deaths in the United States passed 4,600 Wednesday as Vice President Mike Pence issued an ominous warning that America's situation is most comparable to Italy's struggle with the virus, which has pushed that nation's hospitals to capacity and has left more than 13,000 people dead despite a weeks-long lockdown.
