Administration may impose new travel restrictions to stem the spread of the virus in the United States. This comes one day after the cdc warned that its not a matter of if the virus will spread in the United States but when it will do just that. And now a top Infectious Disease doctor tells cnn the outbreak is inching closer and closer to becoming a pandemic. Listen. If we have a pandemic, almost certainly were going to get impacted. We need to be able to think about how we will respond to a pandemic outbreak. Lets get over first to the white house. Cnns john harwood is there and joins me now. John, what are you hearing about this News Conference with the president . Reporter well, i think to some extent, kate, the white house hasnt provided a lot of details but it will depend on what happens the rest of the day. The president has gotten some good news today in the stabilization of the markets, but Anthony Faucis warning of a potential pandemic has underscored the risks of a potential economic recession from the coronavirus. That has got the president extremely concerned. Hes got an executive branch thats not fully staffed. They have discarded the post that president obama set up to handle Global Pandemics on the National Security council. So this president is not in a good place right now. He was unsettled by the fact that his happy talk yesterday and the day before about this being under control has not seemed to be effective. Republican senator john kennedy was grilling his officials yesterday on capitol hill saying youre not giving me answers. I think the presidenciy sees ths News Conference as a chance to provide some better answers than the administration has given so far. John, thank you so much. Much more to come from the white house today. Really appreciate it. One Immediate Impact the coronavirus has is rattling global markets. So far its been another volatile day on wall street and this comes after historic declines monday and tuesday when the dow lost nearly 2,000 points. For perspective, that is 1. 7 trillion in value wiped out in two days. Julia chatterly is at the New York Stock Exchange with much more on this side of this very big story. Julia, what are you seeing and hearing there today . Reporter hey, kate, great to be with you. I can tell you were seeing gains at this moment. We are higher by 1. 5 on the dow. Ill call it a pause or consolidation after five straight sessions of losses. To your point, two really turbulent days on the stock market. I think people here, their heads are spinning. In the space of a week weve gone from seeing the stock market at record highs and questioning whether that made sense in light of the coronaVirus Outbreak. And now weve been flirting with correction territory, so down 10 almost from recent highs. I think to johns point, the announcement of this press conference critical today for giving stability to these markets. Well have to wait and see what the president says. He said that the cdc, the centers for disease control, is going to be there. It was the apparent mixed messages from these two figures yesterday that created a lot of the uncertainty. We simply dont know what the impact is going to be. So i think, again, all eyes, all investors will be watching that 6 00 p. M. Press conference. Of course larry kudlow did say yesterday, the white house economic advisor, i tell you what thats working today but the only thing ill promise you is more volatility. For now were higher but well wait for that press conference tonight. Buy on dips coming from a Top White House official. He handles the economy, is a top economic advisor, but hearing that talking about a very real Public Health threat is sure something. Good to see you, julia, really appreciate it. The Economic Impact is one thing but the most important aspect of this crisis is of course the threat to Public Health from this mysterious virus. The cdc isnt mincing words with top officials saying this. Ill read you the quote from the briefing. They said we expect that we will see Community Spread in this country. Its not so much a question of if this will happen anymore, but rather more a question of when this will happen and how many people in this country will have severe illness. Sdrups to ev disruption to everyday life may be severe. Joing me is dr. Sanjay gupta. You have anthony fauci, a top nih official, also adding that the virus is getting closer and closer to being labeled and reaching the definition of pandemic. Can you put these warnings in perspective for folks . Yeah. Look, as far as the terminology, some of that is just semantics at this point. We are certainly seeing evidence of this virus spreading in many places around the world. What were specifically talking about, what dr. Fauci was talking about is the idea of seeing sustained Community Spread. What that means is in the United States so far youve only had two people who have actually contracted the virus from somebody else, humantohuman transmission. Once you see that happening in larger numbers, so one person transmit it to two or three other people and they transmit it to two or three other people and that goes on for four or five generations, thats whats called sustained Community Spread. And look, the Public Health officials have been very transparent about this to be clear for some time saying this is going to happen. All the massive measures taking place in china, the largest quarantine in history, the travel restrictions, all of that was designed to slow this down. Were talking about a little virus here that doesnt respect borders or boundaries. I interviewed, kate, the head of the cdc last week. I want you to listen carefully as to how he described this. This virus is probably with us beyond this season or beyond this year, and i think eventually the virus will find a foothold and well get communitybased transmission. You can start to think of it in the sense like seasonal flu. The only difference is we dont understand this virus. So a foothold, kate, something thats going to start spreading within communities. Again, Public Health officials have been saying this for some time. They wanted to buy time, slow this thing down, knowing that it would eventually start to spread. And so theres a lot of talk about what the government is doing to prepare or what they if they have done enough, where they are in terms of preparation. But what should everyone else be doing, sanjay . Are you hearing that folks should start stocking up on diapers . Should people start Wearing Masks outside already . I think a lot of people just want to know simply what they can do. The practicality of this for people. Look, to be fair, were not there yet. I mean we are saying when, not if, but were not there yet. Theres still only 57 people who have been diagnosed in this country. And so if you have symptoms, its still exponentially more likely to be the cold or the flu versus coronavirus, but its a really important point. Look, kate, ive covered lots of outbreaks over the years you were on the ground covering ebola, i remember that distinctly. Yeah, in west africa. But here in the United States i think once we start to hear about the Community Spread, again, people are saying thats going to happen, i think the name of the game, what people will talk about is this idea of social distancing, trying to isolate people as much as possible, as much as reasonable for a period of time. A couple of weeks perhaps. And that means kids staying home from school, people trying to work from home. But also, you know, do you have your medicines in case you cant get to the pharmacy . Do you have enough supplies . Look around your house. If youre told, hey, look, im not going to leave the house for up to a couple of weeks, do i have what i need here, thats the sort of preparedness planning that people often talk about in the midst of an outbreak of some sort. Hospitals will probably cancel elective operations and be focusing on surge capacity. Big gymnasiums, big public buildings will be thought of as not just public spaces but possibly isolation areas. So the whole community from the medical side, the social side, schools, all that starts to change. But i think the biggest thing is you want to distance yourself from people for a bit because you dont want to contract this virus. Are you in a position to do that . I think thats the practicality of it. If you have young children, it does mean diapers. If youre an older person that takes meds, it does mean making sure you have enough medications to get you through that time period. Those practical sort of tips. Cautious but vigilant. Thats right. As a mom with a baby at home, you can never have too many diapers is kind of the way i always think of it. Youre always prepared. What about travel . What about people with travel plans outside the United States . I have talked to several folks about this issue. You know, theres been a lot of back and forth regarding travel restrictions. Yes. I dont think this idea of people being restricted, travel into the United States from other countries, is probably going to be that meaningful once you start to see so many areas around the world where the virus is spreading because youre talking about south korea, italy, iran, all these different places. But i think what you are going to hear is travel advisories for people within the United States to these other countries. So you want to check to see is there a travel advisory. The highest is saying dont travel there and then theres nonessential travel. But you can look. The state department is continuously updating that. I wrote down italy is a level 2 travel warning right now, iran a level 4. You want to check that and determine whether your travel still makes sense. Those two websites like Amy Klobuchar offered on the website, cdc. Gov, thats very important as well as the state Department Website as far as those travel updates. Of course well bring them as soon as we get each and every one of them, thank you, sanjay. Coming up, former Vice President joe biden picks up a big endorsement this morning in South Carolina.

A big morning for former Vice President joe biden, picking up the biggest endorsement for a democrat in South Carolina three days before the states primary. South carolina congressman jim clyburn, the highest ranking africanamerican member of congress, announcing this morning that hes throwing his support behind biden, encouraging democrats in the state to do the very same. That stamp of approval coming on the heels of a raucous and really messy debate last night, literally turning into a freeforall between the seven candidates on the stage. Frontrunner Bernie Sanders taking the most attacks. Listen to this. I think i would make a better president than bernie. Imagine spending the better part of 2020 with Bernie Sanders versus donald trump. Think about what that will be like for this country. Bernie sanders analysis is right. The difference is i dont like his solutions. Bernie in fact hasnt passed much of anything. I do not think this is the best person to lead the ticket. To keep on going, we will elect bernie. Bernie will lose to donald trump. Cnns jeff zeleny is in charlton, South Carolina. Jeff, first the endorsement. What does this do for joe biden . Reporter kate, i think theres no question, this is the endorsement joe biden has been waiting for. Theres no one who is more well known and has supporters looking to him for guidance here. If you consider about half of the voters in South Carolina, the democratic voters have told pollsters that they are still open to changing their minds. An endorsement from congressman clyburn certainly could be beneficial. I was just at their endorsement event just a short time ago this morning. I was struck that he said we not only know joe biden, joe biden knows us. Listen to how the former Vice President accepted that endorsement, talking about a revolution. Take a listen. Today people are talking about a revolution. What the country is looking for are results. What theyre looking for is security. What theyre looking for is being able to sustain and maintain their dignity. Reporter so no question joe bidens central argument here in the final days of the South Carolina primary is that he is a security blanket, if you will. He is a bit of comfort, if you will. He went on to talk about obamacare, the Affordable Care act, about how that has saved so many families there and of course points out that medicare for all supported by Bernie Sanders would take people off of their private insurance. So it is amazing the degree to which barack obama, the former president , is hanging over this contest here. Joe biden trying to hold tightly on to his legacy, his policies, to turn out that africanamerican vote and others here in South Carolina. He needs a win on saturday, kate. Otherwise he knows he cannot go forward. So what are you hearing about last nights debate . Reporter theres no question that Bernie Sanders took all kinds of incoming. The question is does it change his trajectory. None of it was necessarily new. These arguments have been being made really for the last year or so but it is a different moment of the debate. I think we frankly have to wait and see how voters digest all of this, not just here in South Carolina but also in super tuesday states. Those 14 states that will vote a week from yesterday. Some of them are casting early votes right now. So how voters sort of internalize all of those critiques, it certainly wasnt a great night for Bernie Sanders, but i think he with stood it as strongly as anybody could being attacked from every direction you can possibly think of, kate. And at some points who knew who was attacking who because they were all just yelling on top of each other. Freeforall. Joining me right now jim messina. Jim, first your take on the clyburn endorsement, how important . Its a big moment. Im skeptical of endorsements usually but jim clyburns is the one endorsement i would wanting in South Carolina. He has real organizational skills. He has real field on the ground. And more importantly, hes the person that people look to to say who should i vote for . And with half this field undecided with just a few days left, thats the endorsement i think is a very significant one. Thats so interesting. So then about last night, everyone going after Bernie Sanders. Do you think anyone left a mark, though . Its a good question. Some of these people need to start doing it on tv and on digital and with paid communication. I think the one hit that hurt him last night was joe biden going after him on gun control, saying you voted against the brady bill five times. I think thats the hit i think could have some lasting impact. And it was interesting to see how Bernie Sanders dealt with those attacks, kate. I think for the most part he just tried to stay above it, ducked and went back to his message pretty effectively. So a lot of people punching him, but im not sure that he took some blows that hell really be feeling this morning. Yeah. And then there are a lot of folks who
