23. However, late Monday morning that site was updated to say ordering would begin in "late September 2024." The federal program for free COVID-19 tests has been closed since March.

An agency spokesperson has said the tests will detect current virus strains and can be ordered ahead of the holiday season, when families and friends gather for celebrations. U.S.
