The COVID-19 comeback across the U.S. is putting pressure on hospitals at a time when some of them are busy just trying to catch up on surgeries and other procedures that were put on hold during the pandemic.

COVID-19 deaths in the United States have tumbled to an average of about 600 per day, the lowest level in 10 months.

U.S. deaths from COVID-19 are falling again as the nation recovers from the devastating winter surge. But, now, after weeks of hovering around 2,000 daily deaths, that figure has dropped to about 1,400 U.S. lives lost each day to coronavirus. For now, most forecasts show coronavirus deaths falling further in coming weeks as more people get vaccines. That's the age group that's been hit the hardest and still accounts for the vast majority of COVID-19 deaths in the U.S. The tally of coronavirus deaths often lags behind new infections and hospitalizations, since it can take a long time for someone to become seriously ill and die after contracting the virus.
