President Joe Biden announced that the U.S. authorities will purchase and distribute one billion home testing kits.

Federal website, on which Americans can order free tests for COVID-19, will begin operating in the United States on Wednesday, January 19, the White House announced.

Orders will be limited to four free tests per household per month. The tests will be delivered to your home for free.

The idea of creating a nationwide website is a response to criticism faced by the Biden administration due to long queues for testing and complaints from Americans about the lack of tests.

Last month, President Joe Biden announced that the U.S. would purchase 500 million home testing kits, and on Thursday announced that the order would be increased to a billion kits.

The White House said that the tests will be sent within 7-12 days from the date of order through the U.S. Postal Service (USPS). The post office clarified that the delivery time of the tests will be from 1 to 3 days.

The U.S. Centers for Disease Control and Prevention (CDC) recommends home testing for coronavirus when symptoms of the disease such as fever, cough, sore throat, muscle pain appear; five days after contact with a COVID-19 patient; or according to testing protocols established for going to school or work.

U.S. officials stressed that the federal website is just one way to get a COVID-19 test. Starting Saturday, private insurance companies in the United States will be required to cover the cost of home rapid tests at home, purchased in pharmacies and online stores.

The White House estimates that the cost of the first stage of the campaign to distribute home tests is estimated at four billion U.S. dollars.
