"nightline" starts right now with juju chang. >> good evening. thanks for joining us. tonight we return to wuhan, china, the original epicenter of the covid-19 outbreak.

slowly restarting after a nearly three-month lockdown just as some say china may have stayed silent too long. the birth of a pandemic. >> reporter: wuhan, china, a trepidation city on the mend, finding its footing amidst deep scars left by the coronavirus. on the streets, a trickle of shoppers taking their cautious, first steps toward normalcy. on the trains face masks a norm. full protective gear no longer rare. these the remnants of a pandemic that first ravaged this metropolis that 11 million people call home, changing so many lives forever. in this province, more than 3,000 people would pay the highest price. now a fraction of the 8500 lives

lost in new york city. [ speaking in chinese ] >> reporter: a 27 rear o-year-o lost her mother too soon. a 19-year-old who found purpose in doing his small part. and an american who found a second home with his wife in wuhan. the birthplace of their baby girl. >> i imagine it will take a while before things get back to what they were, if ever. >> reporter: tonight, a return to ground zero. the testimony of a city that became the first to live through the scourge of covid-19, and the 76 days of lockdown before it game to reemerge. it was last december in this market known for selling wild animals, the first major cluster of cases are reported. scientists believe the virus could have been transmitted from bats to humans.

the contagion quietly spreading. but in the early days, chinese officials are slow to respond. when i fly to wuhan on january 22 nd, this usually busy airpor empty. there's basically almost no one here. it's empty. their fear at the time, locals heading out, widening the circle of infections. the government is slamming shut the gates to the city. but the virus' tentacles already reaching america's shores where the first travel-related case is confirmed. then on january 23rd, the beginning of an unprecedented lockdown in wuhan. leaving the airport, train stations and the streets nearly deserted. by the next day, more than 50 million people are barred from leaving hubei province. this could not have come at a busier time, on the eve of the chinese new year, one of the

country's biggest holidays. just a mass number of people will be traveling in china and over the borders back and forth and flying to other countries. the spread now seemingly unstoppable. from east asia and beyond. in less than a week, the number of countries and territories with confirmed cases balloons to 15. by the end of the month, the world health organization would declare a global health emergency. in wuhan, the government building two new hospitals in a matter of days as shown in this time lapse on state media. as a foreign national, american max and his wife have a choice to make. >> there was like evacuation flights out of china. it was kind of too much risk. we thought we'd just kind of be exposing our baby. >> reporter: they stay in wuhan and hunker down. max, a teacher, continuing to teach classes, but now online.

>> need to think about how to put them together. >> reporter: for a local teenager, as the spread of the virus grew, so did his sense of duty. [ speaking in chinese ] he's a driver, calls started coming in from doctors who needed help commuting. for him, it was a simple choice. for the doctors he was transporting, the virus, a threat in more ways than one. in early january, chinese authorities reprimanded eight doctors who had sounded the alarm about the new coronavirus. one of them, 34 year old

an opt that moll gist. his death is confirmed on february 7th. grief and anger over government censorship erupts on chinese media, many demanding transparency. >> many speculated that the hubei province was very interested in promoting new year's celebrations and there was a delay on that basis. there were others who say they weren't sufficiently vigilant. >> reporter: but soon, quarantine enters full force. authorities seen dragging a couple from their apartment after they reportedly refused to self-quarantine. >> reporter: another develops a cough and a chest scan reveals a lung infection. but even after testing positive for covid-19, there are no available hospital beds. on february 10th, a bed finally opens up at a local hospital, with her mother no longer able

to walk, nina takes her in on a wheelchair. this was the last time she saw her mother. for max, it wasn't his own situation that worried him most but his family back home in colorado. cases in the u.s. were climbing. by mid march, huge institutions like broadway had shut down. the very next day, president trump declared a national emergency. and by march 17th, coronavirus would be in every single state. >> my grandparents, i worry more about them just because, you know, they're elderly, so more at risk. it's kind of surreal to see that things have flipped. >> reporter: at the end of

march, wuhan takes its very first steps toward emergence, a return of workers to a honda factory. no one is allowed to enter or leave the city without special permission, but restrictions are finally relaxing, a tiny bit. >> we've left the neighborhood. there, you can see the bike barricade. it no longer has any power over us. it's a good feeling. >> reporter: a welcome glimpse of normalcy, emerging from the once-desolate streets. >>'s kind of weird leaving the neighborhood. there's still all these guards set up and stuff. and you have to scan a qr code to get out. >> reporter: part of how wuhan is managing the spread is through extensive tracking and surveillance, as residents go almost anywhere, they scan a qr code that shows if you're healthy, infected or have come into contact with someone who is infected. officials also use technology to check body temperatures.

police even wear helmets they claim can detect heat in a crowd. >> we don't really have the surveillance and commitment to surveillance that the chinese have shown. and this is how they were able to get things under control. >> reporter: far from the epicenter, china now reporting a resmurns of new cases, along its remote, northern border with russia, attributing it to travelers crossing over. almost 100 days after the first reported death, this is wuhan, the blossoming spring brought with it the sunshine. those yew pick wittous face masks, a stark reminder of all the city has been through. nina has since returned to work as a beautician, but she carries the memories of her mother with her.

ask your health care provider today about once-weekly ozempic®. in a now-viral 2015 ted talk, microsoft founder and philanthropist, bill gates warned about the danger of pandemics. now he's not pulling punches, challenging a decision by president trump to halt funding to the world health organization, this as he and his wife boost their contribution to the fund to $250 million. revealing to david muir in an exclusive interview what think think we need to reopen the

country. >> there's going to be a lot of time to look back and what we could have done better to prepare for this. and we're all learning lessons in real time. but let's talk about where we are as a country right now, bill. what should we be doing right now in the middle of this storm? >> we're still in the very acute phase where strong adherence to this social distancing is absolutely key so that we get to the peak and those numbers really start to come down. you know, within a month or so of obtaining that peak, if we put in place the right prioritized testing, where you, the right people are tested and they get quick results and we have contact tracing, then we will be able to start reopening up, but it won't be a totally normal situation until we get a vaccine so that everybody's protected. >> we've heard a lot from the president about the 30 days of social distancing. that takes us to may 1st, which is now just a couple weeks from now. do you see a possibility of the

country reopening in just a couple weeks, bill? >> well, the numbers should drive us here. and a group we fund called international health and metrics evaluation is showing that the numbers are starting to come down. and maybe in late may, you know, we'll have one per 100,000 act cases, because you don't want to shut down again. and, you know, the governors have been good leaders, so that dialog between the experts and the leaders, i think that's happening now, and our foundation is part of that dialog. >> and even when we talk to the institute for health metrics and evaluation this week, one of the discussions we were having with them is we all need to learn as places in spain start to open slowly, different regions. and even in the united states, where the epidemic came first, and where we can open slowly and watch and see what happens. particularly because we need to have more of the testing and the contact tracing.

and you're seeing some places in the united states where the testing still isn't at all what it needs to be. >> so what do we need to do right now in order to reopen the country, to get back to, you know, some sort of normalcy and sort of set a new normal, whatever the new normal is? >> well, i will say it's three phases, the acute phase we're in now, the semi-normal phase until we get a vaccine and the truly normal phase after the vaccine has protected all of us. that vaccine is probably late 2021. so the semi-normal period, you know, starting whenever it does, a month, two months from now, will be quite long. and the idea, you know, is that it involves masks, how dense is the seating at restaurants and the testing so that you immediately see if you have that exponential rise in any part of the country, and you can go in there and make sure that you isolate and don't get up to a lot of people infected, which would cause a lot of death.

so fixing that testing regime, we need to have that in place before we move to that next phase. >> so do you have confidence? a lot of americans are going to say wait a minute, we just watched what happened when we really needed the testing in the beginning of this, the testing simply wasn't there. are we going to have tens of millions of tests ready in a few weeks' time to test folks before we try to re-enter society? >> well, the testing will move as we up the capacity, so that the people who have the symptoms are have been around somebody who tests positive, they'll get it sent to their home, so they won't have to go in. and we got the fda to approve a thing called self-swab where you don't need a medical person to do that, and it's got still the high accuracy. so that approach, right now, it's a dialog with the governors. we'll see if the federal government wants to get

involved. that will really help with the opening up phase, and it's not just the, when the government tells us we can go and do things. you know, people are worried. and so they're not going to immediately change their behavior. and yet, if we really got the right things in place, getting back the economic activities is actually a good thing. >> and even just home swabbing, the kits need to come, and then you get 24-hour turn around, so you know whether you actually have it or not, very, very rapidly, and yes, it will mean people doing the right thing and self-isolating themselves. so i think people will realize that they need to do the right thing and i trust that americans will, but they need the testing. >> melinda, i think you're absolutely right. americans deserve a lot of credit. they did listen to the warnings and stayed home. i'm struck by when you talk about the phases, the

semi-normal phase that you spoke of, that sounded like months and months of that, if a vaccine is still not until 2021, that's many, many months of this new normal. >> that's right. it's almost certainly over a year where large public gatherings likely won't be taking place, we're likely to be using masks, even in restaurants, there will be some degree of spacing. the asian countries that saw the disease first are still requiring all of these things. and so we need to learn from them. they've been able to do it without seeing a big rebound. so that definitely is good news. the contact tracing, we have to do that in a twway that preserv privacy because of the values we have. and that's very achievable if we put the right system in place behind it. >> our thanks to david. up next, in times of uncertainty, why wait for happily ever after?
