on that subject, neil, you heard david culver.hy -- why is it so hard for scientists to pin this down? >> oh. because the -- this piece of debris is not sort of a perfectly-modelable, spherical object. and when you have something that is highly angled and highly non-aerodynamic. you have no idea, especially going at the speeds that it does, you have no idea where it will ultimately land until it's kind of -- till you're close enough to that ultimate point where you say, okay, now i got this. but until then, the tumbling object becomes very hard to predict. >> one of the things that i think is most interesting about the discussion here is the difference between the fact that it's incredibly unlikely that anyone will be hurt by this. and the fact that it -- it's a non-zero chance, though, that someone could be hurt by this. so, you know, explain that. >> well, so -- so, as was noted in the graphic, more than 70% of earth's surface is water. so, you -- you're doing good there. and half of all the world's population lives in cities, h

we have more from david culver. >> president biden is ordering the intelligence services to dig deepero where the first origin of covid-19 was found, wuhan. was it a natural spread from animals to humans and amplified in this once crowded wuhan market. was it a leak from this lab. >> we know that china started a massive cover-up starting on day one destroying samples, and imprisoning people and placing a gag order. >> reporter: it has been a well over a year since the outbreak, and no conclusive answers. former trump made claims that it started with the wuhan virology lab, but many dismissed his lab leak as a conspiracy. president biden took a more international approach to investigating the lab. biden also shutdown trump's inquiry because of concerns about the quality of the evidence, but now with new intel, what did china know and when? new intel shows that researchers at the lab were so sick they had to go to hospital, and that is weeks before they reported covid symptoms to the w.h.o. there is mounting pressure on the biden administration to find answers. we were in wuhan as the w.

joining me right now is david culver in shanghai with more on this intelligence report. and what you can take from it can't extrapolate, can't what we do with it now. what are you learning david? >> it doesn't bring us right to the origin of this virus which i know most folks are trying to figure out. and they would want to know. especially the w.h.o. experts and really scientists around the world. but here's what we can tell you from this report. it suggests that the researchers working at the institute of virology, you have to remember wuhan is where the original outbreak of this virus was. were apparently so sick that they had to go to the hospital in november of 2019. now that is a significant amount of time, several weeks really before this outbreak really took hold. and chinese officials have been pushing back on this for more than a year now. they have suggested that it did not leak from a lab. the original source was believed to have been the seafood market. that is an area that was shut down rather quickly january 1st of 2020 and scrubbed clean. but now the new i

cnn's david culver is joining us from shanghai.what have we learned about the potential birthplace of this pandemic? >> well, wolf, we knew going back to the state department fact sheet that these three wuhan workers had been sickened and had flu-like symptoms. what we are hearing is they were so sick they had to be hospitalized. the white house was asked about this. they didn't get into details on the intel. instead they said that the w.h.o. needs better access so as to learn the facts. the w.h.o. has been here in china. they had a field team in wuhan earlier this year. we were down in wuhan in january as that field team was under way going through the sites, and the seafood market as well as the institute of virology. they claim it is extremely unlikely that the origin of this virus is a leak from the lab is that many of the members on the team were concerned with the amount of transparency and just how much access to the crucial data they were getting. in fact, they claimed that the chinese were limiting them in many ways. >> i

nguyen is the author of "lifelines, a doctor's journey for public health" and david culver that reportedstudied the chinese health care system. what do you make of the new reporting. >> there are a lot of unanswered questions and i think it's important for us to get to the bottom of this because this is a global pandemic that's killed 3.5 million people. we need to understand what the origin is. if there is an animal between mats bats and humans, we need to understand because there may wbe a reservoir. if this is a lab leak, we need to understand for lab safety prot protocols. in this case, i don't know. there is a report of three lab researchers that sought medical care but keeping in mind medical care in china is different. there isn't much of a primary care system so -- common for people with flu-like symptoms to go to the hospital. were they hospitalized for a long time? tests were done? about timing? did they go to the hospital in november? were they the first people to get coronavirus or did they get coronavirus in the community because it may have been circulating before? so many

cnn's natasha -- and david culver are following this for us.atasha, what are you learning about how this piece of intel fits into what the u.s. knows about the origins of covid-19? >> reporter: it's another piece of the puzzle, ana, the u.s. intelligence community has low confidence in its assessment of the origins of the coronavirus pandemic, meaning that they don't really know exactly where, how or even when the pandemic spread. what this does, though, is it kind of up the timeline a bit with regard to the potential theories about where this pandemic actually began. importantly, though, the intelligence community still doesn't know whether these researchers were actually sick with coronavirus. all they know is they had symptoms consistent with covid-19, that also could have been consistent with other seasonal illnesses like the flu, for example. so while this does provide another kind of data point for the intelligence community to look at with regard to potentially the idea that this could have leeked from a lab, one of the many labs that wa

you heard david culver when, where and how much are the questions of this hour for the chinese rocketrd for scientists to pin this down? >> oh, because the piece of debris is not sort of a perfectly spear object and when you have something that is highly angled and highly non-aerodynamic, you have no idea especially going at the speeds that it does, you have no idea where it will ultimately land until it's kind of -- until you're close enough to the point you say i got this. until then, the tumbling object becomes very hard to predict. >> one of the things that's most interesting about the discussion here is the difference between the fact it incredkcredibly unl anyone will be hurt by this and the fact it's a non-zero chance someone could be hurt by this. explain that. >> well, so, as was noted in the graphic, more than 70% of earth's surface is water. so you are doing good there and half of all the world's population lives in cities, hovered together around very small pockets of area on earth's surface and so much of land is uninhabited like siberia and central china and pacific sout

cnn's david culver is live in china and chinese authorities say this is all a smear against china, evenigin of coronavirus came from. >> reporter: christine, anything that suggests that the or day inis a lab in wuhan specifically the wuhan institute of virology, has been considered by china for the past year plus to be a smear campaign, to be hype, to be a defection and they're continuing with that narrative. as you mention it seems the biden administration is facing growing pressure to get to the bottom of this and it looks like with this now new probe pushed on by the intelligence community in particular they're looking at two possible theories, the lab leak as we've mentioned and the possibility that it occurred naturally from animals to humans and then spread likely in a wet market or a seafood market which was believed to be the original epicenter of all of this. the chinese officials are continuing to push back, we heard that a couple hours ago. here is just a snippet of what they had to say, the spokesperson from the podium at the foreign ministry saying, quote, this is disrespec

cnn's david culver is live for us in shanghai. david, good evening to you. thanks for joining.u know, this report raises so many critical questions about the origins of this pandemic. what else can you tell us? >> reporter: it is really disturbing, don, to think not only that these researchers who worked within the wuhan institute of virology, that high-level lab within the city in which this outbreak was first detected, were sickened but also now through this intel, the severity of their illnesses. just how sick they were, suggesting that they had to go to the hospital. so we don't know exactly what they had, and part of that could be because just going back to that time, november of 2019, we didn't have the testing for covid-19. and the chinese likely did not have the testing at that time. however, what it does do is it challenges the timeline and the narrative that have come out from chinese officials here, suggesting that the virus didn't really start until december 2019 in wuhan and spread not from a lab but rather in the seafood market. that was, if you remember, the init

at the statement, david culver as well. let's begin with your reporting here. do they have more confidence now in this intelligence this evidence and, therefore, the true origin of this virus? >> jim, this piece of intelligence we are being told was in a u.s. intelligence report is just that. it's only one piece. it does not give the u.s. intelligence community writ large any more confidence to know exactly precisely when and where the covid-19 virus originated. what we should note, this is new and note worthy because what we're learning is the researchers in november of 2019 sought hospitalization because of these symptoms that they were facing. it builds off of what we have learned in previously declassified information provided by secretary of state mike pompeo on his way out the door as the trump administration was leaving. but the big picture here, you know, director of national intelligence told congress earlier this year that the u.s. intelligence community still does not know precisely when this virus originated, how and where it did. st so there is sti

. >> our david culver is live from beijing this morning. david, walk us through this change.is is huge. and this cannot be understated. you are right, jim, when you look at the history of the one-child policy which dates back to around 1979, that ended in 2016, but for that period of time there were such extremes that the government went to to try to force people to keep to that one child, everything from fines to imprisonment to even forced abortions. that extreme has not been lost on the folks today. so when they see changes from 2016 until more recently, 2021 when they had two children, now this talk of moving forward with allowing for three children, the hope on the government's part is to encourage people to have more kids. why? what are they looking at in particular? they are looking at this aging population that is not going to be supported by a strong enough workforce if there is not enough people to provide for t i will show you the numbers right here. if you look at one year in comparison, you saw a drop in the birth rate of nearly 15%, meantime the 65 and older the

i want to go to david culver in beijing and he's been trying to walk us through exactly what's going jing say the chances of this rocket's re-entry causing any harm or damage are extremely low, but they stop short of guaranteeing a safe re-entry. meantime, u.s. officials are increasingly concerned of the growing amount of congestion in space, and they are following this rocket launched by china very closely. >> what goes up, must come down. the question is, where? scientists say they will not know the exact entry point of the 22-ton chinese rocket until it's so close it's only hours away from re-entry. experts say don't panic. this is not like the hollywood blockbusters where the impact of something from outer space threatens to end the world. but uncontrolled space junk crashing back to earth is a growing concern. what's expected to hit earth this weekend is the empty core of a rocket that's been losing orbit since its launch, much of which should burn up in the atmosphere. but some pieces could get through, like last year, when the largest piece of space debris in 30 years landed in

david culver is following the latest for us. is that true? >> let's hope. right?tly it will come in to the earth's atmosphere. and where it's ultimately going to end up. that is the frustrating part of all this. what is interesting though is how it's being portrayed here. that is not being widely publicized. the u.s. side of things is obviously portraying this as an out of control rocket. a very large one at that. 100 feet high. much it's 22 tons. it goes 18,000 miles per hour. here though, one state media article that we came across suggested that this is just media hype from the western media. what is interesting though, they are saying the likelihood is it will end up in the pacific. and won't cause any major issues. however, there's no guarantee. i think that is the ultimate concern. this is an out of control rocket. what i do go back to jim and poppy as they're calling this media hype here, i go back to february of 2020 when i was covering the outbreak. they said that the u.s. was overreacting when it comes to the coronavirus outbreak. you have to put things
