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

JUANA SUMMERS, HOST:

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

(SOUNDBITE OF LUGGAGE CONVEYOR BUZZING)

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

(SOUNDBITE OF LUGGAGE LANDING ON CAROUSEL)

COMPUTER-GENERATED VOICE: Your baggage receipts…

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

ANA VALDEZ: Hey, everyone. Welcome. Hey. Welcome.

STEIN: Ana Valdez is already onerous at work at one of many worldwide gates, the place arriving vacationers are flooding by means of two large, swinging doorways.

VALDEZ: Do you want to assist the CDC to seek 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 would spawn a brand new, much more harmful variant. Valdez and her colleagues are gathering samples from vacationers coming in from China, but additionally different international locations the place the virus is spreading quick.

VALDEZ: It’s going to 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?

UNIDENTIFIED TRAVELER #1: From India.

VALDEZ: Do you want to assist the CDC to seek out new variants of COVID? Do you want to assist? It will take 35 seconds of your time, then we are going to go away you…

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

VALDEZ: Have a very good 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 only need to go house.

STEIN: I get it. I – that is the best way I’d really feel, I believe.

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

STEIN: Over and over, Valdez guarantees to make it fast and straightforward and presents a free speedy COVID check to take house as an incentive. One pandemic-jaded traveler jokes he’d volunteer in the event that they provided him a free Starbucks as a substitute. She tries once more.

VALDEZ: The place are you coming from?

PETER YUKA: From Nigeria.

VALDEZ: Nigeria is without doubt one of the international locations of curiosity for the CDC, so your assist will likely 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’ve gotten, in the event you had been constructive up to now, and we simply – give us a pattern out of your nostril.

YUKA: For COVID?

It is fairly embarrassing. I’ve accomplished 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 kind saying he is totally vaccinated and by no means examined constructive for COVID.

VALDEZ: You may sanitize your arms 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 arms 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 technique to examine in Texas.

So what do you concentrate on this?

YUKA: I believe it is cool. I believe we should always do no matter we will to battle the COVID. And, I imply, I noticed the injury it did to the entire world, and international locations like mine had been actually badly affected. So no matter it’s I can do to assist, I am prepared to do it.

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

CINDY FRIEDMAN: Every time you’ve gotten viral transmission, these viruses are good. They will 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: Now we have a deal with China proper now as a result of there’s a lot unfold and so little knowledge or data. So we need to make it possible for now we have eyes on what variants are popping out of China, however we’re additionally holding 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 gather samples from greater than 4,000 passengers every week. However many scientists doubt that China poses an enormous danger proper now. The latest hypertransmissible variant taking on within the U.S. in the meanwhile originated in New York. Michael Osterholm is on the College of Minnesota.

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

STEIN: And a few say it will make extra sense to sequence virus from wastewater from planes, as a substitute 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 had been strolling by means of an airport and I wasn’t feeling nicely, and I used to be requested if I needed to take part in a COVID surveillance program – even when I had been assured that it will be nameless – I do not suppose I’d be prone to need to take part in that surveillance program. You may 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 does not appear to be a lot that anybody is ready to do. We have to have clear steering round how we are going to truly 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 many others.

STEIN: Friedman, on the CDC, says the company is taking steps to probably monitor wastewater from planes. Within the meantime, she says, each bit of knowledge is helpful 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 try to get extra each day.

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

STEIN: Rob Stein, NPR Information.

VALDEZ: So the place are you coming from?

UNIDENTIFIED TRAVELER #2: Taiwan.

VALDEZ: Do you want to assist the CDC?
