Individuals must also “rethink journey to China, Hong Kong, and Macau,” the CDC now urges. In a travel alert printed Wednesday, the company cited “stories that the healthcare system is overwhelmed,” together with the chance of recent variants.
Past masking whereas touring in locations like airports or planes, the CDC additionally recommends that Individuals visiting China put on masks whereas indoors in public.
The strikes come amid a report wave of infections in China because it relaxed its “zero COVID” policy in early December. The Chinese language authorities has additionally begun to ease travel restrictions that have been imposed years in the past, early within the COVID-19 pandemic.
“CDC is asserting this step to sluggish the unfold of COVID-19 in america through the surge in COVID-19 circumstances within the [People’s Republic of China] given the shortage of sufficient and clear epidemiological and viral genomic sequence information being reported from the PRC,” the CDC mentioned in a statement.
Starting Jan. 5, airways might be required to gather proof of a adverse COVID-19 take a look at from all passengers ages 2 and older earlier than they will board flights out of China into the U.S. Each lab-based PCR assessments in addition to antigen self-tests might be accepted, so long as they’re overseen by a well being care supplier.
Vacationers on connecting flights can even be required to offer proof of a adverse take a look at.
Folks touring to the U.S. by means of South Korea’s Incheon Worldwide Airport, Canada’s Toronto Pearson Worldwide Airport, and Canada’s Vancouver Worldwide Airport might be required to check adverse if they’ve been in China during the last 10 days.
“These three transit hubs cowl the overwhelming majority of passengers with journey originating within the PRC and the Particular Administrative Areas. We’ll proceed to watch journey patterns, regulate our method as wanted, and hold Individuals knowledgeable in a well timed method,” the CDC mentioned.
Federal well being authorities haven’t required adverse COVID-19 assessments from any worldwide guests because the requirement was scrapped in June. The U.S. continues to require that each one international vacationers show they’re totally vaccinated with the primary series of a COVID-19 vaccine.
Officers mentioned Wednesday that they have been ready till subsequent week to impose the measure to permit for airways to implement the revived necessities.
“It does take some effort by the airways to replace their information programs to place this all in place. And so we’ve to make this announcement right this moment, however it can take time to implement this system,” a federal well being official advised reporters at a briefing.

Concern over COVID variants
Along with the brand new requirement, the CDC mentioned it’s transferring to increase its present variant surveillance efforts to 2 new worldwide airports in Los Angeles and Seattle.
The company has already been monitoring variants over the previous few months noticed in voluntary assessments collected from arriving worldwide vacationers. Wastewater collected from some plane bogs are additionally now being examined for variants, the CDC says.
A complete of some 290 weekly flights from China and close by nations might be coated by this system as soon as expanded, the CDC mentioned.
“We’ve got very restricted info in public databases about variants which might be circulating in China presently. Prior to now few months, solely a couple of hundred sequences have been uploaded,” mentioned the federal well being official.
They cited the risk the virus might pose because it infects an enormous swath of “immunologically naive” individuals in China.
“What we’re involved about is a brand new variant that will emerge truly in China, with so many individuals in China being contaminated in a brief time period, there’s a likelihood or likelihood {that a} new variant will emerge,” mentioned the official.
Scientists have voiced frustration over sparse variant sequencing launched from China amid the nation’s present wave of infections, apart from a handful of vacationers.
All the present variants circulating in China are descendants of Omicron, Chinese language state media have reported, quoting their nation’s well being officers, with BA.5.2 and BF.7 dominating infections within the nation.
First noticed earlier this yr, these two strains have made up a fraction of circulating virus within the U.S. so far. As an alternative, the CDC’s estimates rank the BQ.1, BQ.1.1, and XBB strains as far outpacing them across the nation.
Infections linked to XBB has surged throughout the Northeast in current weeks, climbing to greater than half of recent infections throughout the area. Forward of Christmas, federal information reveals hospitalizations reaching among the highest charges since final February within the Northeast.
Scientists imagine a descendant dubbed XBB.1.5 is behind the renewed surge, with immune evasive mutations that seem to bind properly to human cells.
