【简答题】
The mayor of the city of Miami, Francis Suarez, has ___1____ for COVID-19. And he's been giving updates on social media. FRANCIS SUAREZ: Last night, I was feeling a little bit of ___2_____ . You know, I took one 500 mg Advil - sorry - Tylenol Extra Strength. I've been hydrating a lot. GARCIA-NAVARRO: As the coronavirus has spread out of China, there's been an __3___ about who is getting infected. Oftentimes in outbreaks - take cholera, for example - the disease devastates low-income neighborhoods first. It's far more likely to turn up in densely populated working-class areas than at a country club, say. COVID-19 seems to be behaving differently. Once it departed from China, the global spread of the virus has touched the highest echelons of society. One reason may be elites are getting ___4____ . But there could be other explanations. To help us understand, we're joined now by NPR's global health correspondent, Jason Beaubien. Hey, Jason. JASON BEAUBIEN, BYLINE: Hi, Lulu. GARCIA-NAVARRO: All right. So this is something very interesting... BEAUBIEN: Yeah, it is. GARCIA-NAVARRO: ...About this disease. It's almost like it seems the global spread has __5___ a certain strata of society. It's people on cruise ships. It's members of Congress and politicians. I mean, we should say that it's not just __6__ those people, but... BEAUBIEN: Right. GARCIA-NAVARRO: ...It's certainly notable that they've been affected. BEAUBIEN: It is very notable. And it's quite interesting. I mean, one of the first ____7___ in Europe in late January was among these 21 people at a ski resort in France. And one of them had come over ___8___ . And he appears to be the one that carried the virus with him to France. And this group of ski buddies then ___9____ . And some of them went to the U.K. And some went to Spain. And others went to other parts of France. ___10____ of those 21 ___11___ testing positive. You know, and we've seen these other clusters on cruise ships. You know, this might seem like cruise ships have something to do with transmission. And that could be true. But again, this is among people with a certain amount of ___12___ that can afford a cruise. I was based - not based, but I was working out of Hong Kong earlier in this outbreak. And some of the very first cases in Hong Kong - they turned up at the Four Seasons Hotel and the W Hotel... GARCIA-NAVARRO: Not cheap. BEAUBIEN: No, not cheap - some of the most expensive hotels in Hong Kong. So so far, we're not seeing that many cases in the ___13___ of the world, like in Africa or Central America. And when we do, it turns out it's primarily among people who've been arriving __14_____. GARCIA-NAVARRO: But it's not just among the upper-middle classes - right? - who are on cruises or can take foreign vacations. There's another group here... BEAUBIEN: Yeah. GARCIA-NAVARRO: ...Which is ___15____ . We're seeing among the real social elite - politicians, sports stars, actors. BEAUBIEN: Yeah. It's kind of incredible to see that of all of the cases that are out there, eight members of Congress somehow ____16____ with them are now self-quarantining. You've got the Miami mayor, Francis Suarez - he's tested positive. And he did four days after meeting with the Brazilian president Jair Bolsonaro, who also met with President Trump. And one member of that delegation has tested positive. So it's circling around, you know, the ______17____ . GARCIA-NAVARRO: OK. So why is this happening? Why would so many of these early cases be among the _18_ , the _19_ or the _20_ ? BEAUBIEN: To be very clear, we really ___21______ for that. And there's a lot about this disease and the transmissibility of it that we don't know. Researchers are studying that. And to be clear, yes, thousands and thousands of people who are not rich or famous or... GARCIA-NAVARRO: In Iran... BEAUBIEN: Right. GARCIA-NAVARRO: ...And other places, sure. BEAUBIEN: And other places are also getting it. But one thing is that this disease - it matters who you come in contact with. You know, it's different from some pathogens. I like to think about it __ 22__ . This one is like mice. Some pathogens, like, they come into the room - it's ___23__ . And they just spill all over the floor and go everywhere. This one, it's like the mice can only travel from one place to another on a plane. And they travel there, and they get caught. Then it goes away. But if they ____24_____ , then they can go somewhere else. And then you get these other people who come in contact with them, and they can become infected. So it's about these ____25____ . And that's really what this is showing. And this one, so far, seems to be among people who are out schmoozing, people who are at conventions - they are far more likely to get this virus. GARCIA-NAVARRO: That's NPR global health correspondent Jason Beaubien. Thank you very much. BEAUBIEN: You're welcome.
