The Biden administration has launched its program to distribute free COVID-19 tests to U.S. residents by mail. Visitors to the website covidtests.gov can order four tests per household, which will be delivered by the U.S. Postal Service. The government will also start issuing 400 million N95 masks from the national stockpile. They will be available for free at community health centers and pharmacies across the U.S. Some health experts say N95 masks should also be sent directly to every U.S. household. The latest efforts from the Biden administration come amid the ongoing winter surge, with daily cases averaging over 750,000 and an average daily death toll close to 2,000.
