Screening at U.S. airports expands to attempt to detect new COVID variants : NPR

The CDC has expanded screening of incoming worldwide air vacationers to attempt to extra shortly spot any new variants which may emerge from China’s huge COVID outbreak.


The huge COVID outbreak in China has prompted the U.S. to increase its efforts to identify harmful new variants shortly. NPR well being correspondent Rob Stein visited one of many websites that is attempting to find new strains of the virus coming into the nation.


ROB STEIN, BYLINE: It is early morning at Dulles Worldwide Airport exterior Washington, D.C.


COMPUTER-GENERATED VOICE: Your baggage receipts…

STEIN: Passengers rush to examine or retrieve luggage, catch flights or taxis.

ANA VALDEZ: Hi there, all people. Welcome. Hi there. Welcome.

STEIN: Ana Valdez is already laborious at work at one of many worldwide gates, the place arriving vacationers are flooding via two huge, swinging doorways.

VALDEZ: Do you want to assist the CDC to search out new variants for COVID?

STEIN: She works for a year-old program that the Facilities for Illness Management and Prevention simply expanded to attempt to spot new variants as a result of China abruptly deserted its zero-COVID coverage. The surge of the virus there may be elevating fears that might spawn a brand new, much more harmful variant. Valdez and her colleagues are accumulating samples from vacationers coming in from China, but in addition different nations the place the virus is spreading quick.

VALDEZ: It can take 35 seconds of your time. It is free. It is volunteer. It is nameless – 35 seconds of your time. The place are you coming from?


VALDEZ: Do you want to assist the CDC to search out new variants of COVID? Do you want to assist? It could take 35 seconds of your time, then we are going to depart you…

UNIDENTIFIED TRAVELER #1: No, it is – I am unable to…

VALDEZ: Have a great day.

STEIN: A lot of the vacationers trudge previous lugging baggage with out even making eye contact.

VALDEZ: Lengthy-time flights, then they needed to cease at immigration and customs, and that takes one other hour or two. By the point they arrive right here, they’re already exhausted, indignant. They simply need to go dwelling.

STEIN: I get it. I – that is the way in which I might really feel, I believe.

VALDEZ: Sure. So it is extremely appreciated that some individuals cease.

STEIN: Time and again, Valdez guarantees to make it fast and simple and provides a free fast COVID check to take dwelling as an incentive. One pandemic-jaded traveler jokes he’d volunteer in the event that they provided him a free Starbucks as an alternative. She tries once more.

VALDEZ: The place are you coming from?

PETER YUKA: From Nigeria.

VALDEZ: Nigeria is without doubt one of the nations of curiosity for the CDC, so your assist will probably be very useful. It is nameless, and it is volunteer.

YUKA: OK. What do I’ve to do?

VALDEZ: Simply must make a signature, give us some details about the – what number of vaccines did you could have, if you happen to have been constructive previously, and we simply – give us a pattern out of your nostril.


It is fairly embarrassing. I’ve carried out the check a few instances. I by no means favored it.

VALDEZ: You do it your self. So you are able to do it as you check.

STEIN: He reluctantly agrees, fills out a type saying he is totally vaccinated and by no means examined constructive for COVID.

VALDEZ: You possibly can sanitize your palms for me?

STEIN: Valdez pulls out a swab.

VALDEZ: You are going to do 4 circles in every nostril. Take it…

STEIN: He swabs every nostril and drops the swab right into a plastic tube. She palms him his free COVID check.

VALDEZ: OK. Thanks, sir. Thanks for serving to.

STEIN: I pull him apart. Peter Yuka is 38 and on his strategy to examine in Texas.

So what do you consider this?

YUKA: I believe it is cool. I believe we should always do no matter we are able to to combat the COVID. And, I imply, I noticed the harm it did to the entire world, and nations like mine have been actually badly affected. So no matter it’s I can do to assist, I am keen to do it.

STEIN: The samples go to a personal lab for genetic evaluation so scientists can spot any new mutations which may make the virus extra harmful.

CINDY FRIEDMAN: At any time when you could have viral transmission, these viruses are sensible. They’ll mutate, and we need to be forward of the sport and early in our detection of recent variants.

STEIN: Dr. Cindy Friedman runs this system on the CDC.

FRIEDMAN: We’ve got a give attention to China proper now as a result of there’s a lot unfold and so little knowledge or data. So we need to be sure that we’ve got eyes on what variants are popping out of China, however we’re additionally protecting a watch on all the opposite areas and the vacationers getting back from these areas.

STEIN: The CDC expanded this system from 5 airports to seven and elevated the variety of flights being screened from 300 to 500 every week, enabling this system to now acquire samples from greater than 4,000 passengers every week. However many scientists doubt that China poses a giant threat proper now. The latest hypertransmissible variant taking up within the U.S. in the meanwhile originated in New York. Michael Osterholm is on the College of Minnesota.

MICHAEL OSTERHOLM: Up to now, we’ve got no proof that there are variants of concern that we have not seen already, and I am unsure that China poses the good threat for brand new variants, essentially. Sure, it is true, 1.4 billion people who may be contaminated – certainly as each new genetic roulette desk throw – however on the similar time, there’s not plenty of population-based immunity, which might be what would drive mutations.

STEIN: And a few say it could make extra sense to sequence virus from wastewater from planes, as an alternative of particular person vacationers, to get a greater image about everybody aboard. Jennifer Nuzzo heads Brown College’s Pandemic Heart.

JENNIFER NUZZO: I can think about, if I have been strolling via an airport and I wasn’t feeling effectively, and I used to be requested if I wished to take part in a COVID surveillance program – even when I have been assured that it could be nameless – I do not suppose I might be more likely to need to take part in that surveillance program. You possibly can think about different vacationers might need to check themselves privately and know these outcomes earlier than the federal government does.

STEIN: However others marvel if the U.S. is ready to behave aggressively at this level within the pandemic, even when the CDC does spot a worrisome new variant. Sam Scarpino is at Northeastern College.

SAM SCARPINO: We have to be having a dialog about what it’s that we do if a novel variant is detected. Proper now, there would not appear to be a lot that anybody is ready to do. We have to have clear steering round how we are going to really go about slowing the unfold, how we are going to defend people who find themselves in high-risk teams, how we are going to work on getting vaccination numbers up, and so forth.

STEIN: Friedman, on the CDC, says the company is taking steps to presumably monitor wastewater from planes. Within the meantime, she says, each bit of data is beneficial to find out how greatest to reply if a brand new variant does emerge. The day I visited Dulles, Ana Valdez and her colleagues managed to persuade greater than 50 passengers to volunteer and are attempting to get extra on daily basis.

VALDEZ: Welcome. Welcome to America. Do you want to assist the CDC to search out new COVID variants?

STEIN: Rob Stein, NPR Information.

VALDEZ: So the place are you coming from?


VALDEZ: Do you want to assist the CDC?
