Easy access to tests could play a key role in fighting the Omicron variant

Experts applaud Biden's plan to expand testing but wonder if the effort goes far enough to stop the spread of the virus

US infectious disease experts largely agree with the Biden administration's newly announced emphasis on Covid-19 testing in the wake of the emergence of the Omicron variant, but questions remain over whether the president's plan goes far enough to ensure that testing stops the spread of the virus.

President Joe Biden announced new actions to combat the coronavirus in the US on Thursday, including a nationwide campaign encouraging vaccine boosters; a forthcoming rule requiring private insurance to reimburse the cost of at-home testing; a pledge to provide 50m free at-home tests to health centers and rural clinics for those not covered by private insurance; and a requirement that travelers to the United States, regardless of nationality or vaccination status, provide proof of a negative Covid-19 test within one day of boarding flights.
