The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.
More than 643,000 Americans have died from COVID-19 while over 4.5 million people have died from the disease worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
Just 61.7% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the U.S. Centers for Disease Control and Prevention.
Over 2.1 million people were screened at U.S. airport security check points Friday — the highest checkpoint volume since Aug. 15, Transportation Security Administration spokesperson Lisa Farbstein said.
Americans have flocked to airports to travel for the Labor Day weekend despite the threat of the delta variant and surging COVID-19 cases and hospitalizations.
