US expected to toughen testing requirement for travelers

The Biden administration is expected to take steps in the coming days to toughen testing requirements for international travelers to the U.S., for both vaccinated and unvaccinated people, amid the spread of the new omicron variant of the coronavirus

“CDC is evaluating how to make international travel as safe as possible, including pre-departure testing closer to the time of flight and considerations around additional post-arrival testing and self-quarantines,” Centers for Disease Control and Prevention Director Dr. Rochelle Walensky said Tuesday.

The official, who spoke on the condition of anonymity to discuss the administration’s plans before the announcement, said options under consideration also include post-arrival testing requirements or or even self-quarantines.

The expected move comes just weeks after the U.S. largely reopened its borders to fully vaccinated foreign travelers on Nov. 8.

Much remains unknown about the new variant, which has been identified in more than 20 countries but not yet in the U.S., including whether it is more contagious, whether it makes people more seriously ill, and whether it can thwart the vaccine. Dr. Anthony Fauci, the top U.S. infectious disease expert, said more would be known about the omicron strain in two to four weeks as scientists grow and test lab samples of the virus.
