The Biden administration announced on Tuesday that 500 million free rapid COVID home tests would be mailed to U.S. households starting from next month, as the country battles its latest wave of the virus.

Government-funded free rapid testing has been part of various countries' COVID responses for months. In Canada, some provinces provide free COVID tests to businesses. In Germany, free COVID tests have been available since March, despite a brief pause in the autumn.
