The plan includes a requirement for private insurers to cover the cost of at-home COVID-19 tests and a tightening of testing requirements for people entering the U.S. regardless of their vaccination status. But as some other nations close their borders or reimpose lockdowns, officials said Biden was not moving to impose additional restrictions beyond his recommendation that Americans wear masks indoors in public settings.

Biden said Wednesday that the forthcoming strategy, to be unveiled during a speech at the National Institutes of Health, would fight the virus “not with shutdowns or lockdowns but with more widespread vaccinations, boosters, testing, and more.”…

Beginning next week, the White House said, all travelers to the U.S., regardless of nationality or vaccination status, will need to provide proof of a negative COVID-19 test within one day of boarding their flights. That’s down from three days right now for those who have been vaccinated, in an added precaution against the omicron variant. But the White House has shelved tougher options, like requiring post-arrival testing or requiring quarantines upon arrival in the U.S.

Biden is also extending his directive requiring masks on airplanes and other public transit, which had been set to expire in January, through at least the middle of March, the White House said.
