The U.S. saw its largest single-day increase in nearly nine months Friday.
The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.
More than 613,000 Americans have died from COVID-19 and over 4.2 million people have died worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
Just 57.9% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.
The CDC on Tuesday, citing new science on the transmissibility of the delta variant, changed its mask guidance to now recommend everyone in areas with substantial or high levels of transmission -- vaccinated or not -- wear a face covering in public, indoor settings.
All patient-facing health care workers in New York’s state-run hospitals must get vaccinated, New York Gov. Andrew Cuomo announced Wednesday.
"There will be no testing option," Cuomo said.
In addition, beginning Labor Day, all state employees will be required to either be vaccinated or get tested weekly.
