As the COVID-19 pandemic has swept the globe, more than 5.4 million people have died from the disease worldwide, including over 825,000 Americans, according to real-time data compiled by Johns Hopkins University's Center for Systems Science and Engineering.
About 62% of the population in the United States is fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.
The U.S. Food and Drug Administration gave emergency use authorization to two over-the-counter COVID-19 tests.
The tests are manufactured by SD Biosensor and Siemens.
"Combined, it is estimated the companies can produce tens of millions of tests per month for use in the U.S.," the U.S. Department of Health and Human Services said in a statement.

The U.S. reported more than 1.9 million new cases this week, which equals about three Americans testing positive for COVID-19 every second.
The U.S. is now averaging 277,000 new cases each day, shattering the previous record average from Jan. 11, 2021, which was 250,000 cases each day, according to federal data.
Although this significantly high number is in large part due to the latest surge, it’s also attributable to the soaring demand for tests and backlogs of data following Christmas weekend.

In New York City, 30% of emergency medical workers and 17% of firefighters are out on leave tied to COVID-19 -- and the fire department is reminding New Yorkers to only call 911 in a true emergency.
"If you are not severely ill, allow first responders to assist those most in need," the FDNY said in a video message.
Meanwhile, the New York Police Department has canceled regular days off for Dec. 31 and Jan. 1 due to COVID-19 and staffing needs for New Year's Eve.

Four Smithsonian locations in Washington, D.C., have closed due to an increase in COVID-19 cases over the last few days.
The four museums -- the National Museum of African Art, the National Postal Museum, the Anacostia Community Museum and the National Museum of Asian Art -- are expected to reopen Jan. 3.
The Smithsonian said the cases and quarantine periods impacted "essential and operational staff," so these closures "will allow the Smithsonian to reallocate staff and keep all other museums open for the remainder of the week.”
The Smithsonian closed in March 2020 due to COVID-19 and loccations started to reopen in May 2021.
