As the omicron variant of COVID-19 surges through the U.S. and with at-home testing kits in short supply, the government is stepping in to offer up to four free tests per household.

Starting Jan. 18, four free tests can be ordered through Covidtests.gov. There will also not be any shipping costs related to the COVID-19 tests.

It is recommended that anyone who is experiencing symptoms of COVID-19 use an at-home test at least five days after coming in close contact with someone who has tested positive.

Tests are expected to ship within 7-12 days of ordering.

Private insurance companies are also required to cover the cost of at-home rapid tests, as of Jan. 15.
