Yesterday. That now puts it in correction territory which means at least a 10 drop. And it happened so fast. Basically a week of the market is down now about 2200 points since the president and his economic advisers adv e advised it was a good time to buy. Revealing more than a dozen federal workers interacted with quarantined americans without proper medical training or protective gear. In california, dozens of workers are being monitored. Some Health Workers will be quarantined. In response to that patient, the cdc changed its criteria for who can be tested in this country. Thats because this patient wasnt tested for days despite her symptoms because she hadnt travelled to a country with the virus nor had contact with a coronavirus patient. President trump trying to calm fears over this global outbreak. Its going to disappear one day. Its like a miracle. It will disappear. And from our shores, you know, it could get worse before it gets better. It could maybe go away. Well see what happens. Nobody really knows. Nobody really knows but it could disappear like a miracle. Global markets, however, are clearly showing the growing concern about this economic fallout. Christine romans joins us now with our top story. Yet another tough day. This has been swift and deep and this is a market coming to a reckoning here that there are risks because of the coronavirus. Companies all across the spectrum have been warn. I want to show you whats been happening right now. These are World Markets down hard. Asian markets down six or seven asian markets are now in what we call a correction. Down 10 from the recent high. Europe opened sharply lower here. Now youve got u. S. Futures again down. This is actually an improvement. Futures were down harder earlier. Six days in a row now for the Dow Jones Industrial average. Let me show you how bad this has been. Youve got yesterdays close. The dow, s p, nasdaq down more than 4 each. Those are big oneday moves. Were not talking about one day. Were talking about a whole week of this kind of behavior. Big, huge losses one after another. You havent seen the investors step in and say this is an overreaction yet. That just hasnt happened yet. Nobody knows when that will happen. Let me show you more about whats been happening. This is what it looks like for just this year. You had record highs in the dow back on, like, january 19th. Just last week you had record highs in the nasdaq and s p 500. And then straight down as investors grapple with the uncertainty of the coronavirus. Real quickly i want to show you actually, i want to show you sorry. The s p 500 over the past ten years because i think perspective is important here. This is this big selloff right there. That is what this is 2018. Remember we had a bad time there. We were worried about recession fears over there. But over time, you know, markets tend to go up. The real trouble here is the president has said you should maybe stocks look good here. Larry kudlow said on monday, maybe you should buy stocks. For people who took that advice, theyre down about 8 . Traditional administrations dont tell people to buy stocks for just this reason. Theres no way to know when the selling could end. Important point. Thank you. In california, dozens of Health Care Workers who were exposed to the patient infected with coronavirus from an unknown source are now being monitored and some will have to be quarantined. Stephanie elam is live outside uc davis where that patient is being treated. Steph, good morning. Good morning, erica, yes. This all because what we know is that this one person who has had no contact, no travel outside of the United States to any of the points of concern, no reason to have this coronavirus at this point. This one person did actually stay in a hospital in the county where she is from which is one county over from Sacramento County here. She was there in her community for a number of days before going to a hospital there. Well, all of the people who work at the hospital who came in contact with her, the hospital has tracked down. Dozens of people but less than a hundred people that they are now monitoring of some sort. Also we know that the family of this woman has been isolated and they are monitoring these people as well to see if they show any symptoms at this point. Thats the big thing that they want to do is make sure this virus doesnt spread because of people who came in contact with her at the hospital. But just to give you an idea, this is what officials in Solano County are saying about this womans progression in how they were able to nail down she had coronavirus. Take a listen. This patient, we dont know what their exposure was. So at this point we dont know where the patient was exposed. The patient was hospitalized in our county at a local hospital, being progressively more ill. Was transferred to uc davis in sacramento. At some point the patient became ill enough to warrant testing for coronavirus and the result came back positive. It is, again, worth noting that the patient wasnt tested prior to that because they werent severely ill enough and had no connection to any of the known risk factors for coronavirus. Reporter now, its also worth pointing out that Travis Air Force base which did accept flights coming with the repatriated americans coming back from china have no reason to believe that shes come in contact with any of those people there at the air force base. And then outside of that, the governor of california saying there are some 8400plus people within the state who are being monitored for whether or not they have symptoms of coronavirus because they traveled in on more traditional flights coming in from points of concern as he put it. So theres while people are looking at these first bit of flights that are coming in or repatriated americans, theyre really saying there are a lot of other places this could have happened. Theyre still trying to narrow it down. Still not clear how this one woman ended up with coronavirus. John . Stephanie, thank you very much. Thats just one case that is causing major concern. But the w. H. O. Overnight going further than it has to date saying that this has pandemic potential. What does that mean . What does it mean especially as there are new concerns in the United States about how few tests have been conducted for coronavirus. Dr. Sanjay gupta joins us next.

By brushing with sensodyne sensitivity gum at home its giving you the relief that you need and the control that you need to take care of your oral health. And it creates a healthier environment. Theres no question its something that i would recommend. Developing overnight. The World Health Organization now says the Coronavirus Crisis has the potential to develop into a pandemic. Much more forceful, that language, uses the word pandemic. This is after more than a dozen countries in the past 48 hours reported their first confirmed cases of coronavirus. And it comes as the cdc has announced it has changed the criteria for testing. We want to bring in dr. Sanjay gupta. Doctor, i thought it was fascinating that the World Health Organization inched closer to using the world pandemic. Anthony fauci when he was still allowed to talk with us the other day, he moved towards the word pandemic. Why is that important especially this morning when you have Major Concerns whether the United States is even conducting enough tests for this. Yeah. I think this is basically a pandemic now. I think the World Health Organization understandably, theyre looking at data from all these different places around the world. It took them some time to even get to the point where they called this a Public Health emergency of international concern. So theyre conservative in their language. Look, we can see whats happening over the last several days. Even the last several hours. Youre getting more and more cases around the world. And you have more and more countries around the world where you have community spread. Take a look at this map for a second where we now know that the virus is not just present in these areas. Theres not just people who have infections in these areas. But the virus is actually spreading within the community. Again, people are understanding what that means now because weve been using these terms a bit, but that basically means that the virus is circulating among people and within the community and you dont necessarily know who those people are. Many of them may not even have symptoms. Many of them may be just mildly ill, but when you say the virus is circulating in the community, it means it no longer depends on people coming from these other places such as china. It means they no longer have known exposures to infected people. The virus is just taking foothold in these communities. Public Health Officials in this country have been sounding the alarm on this for some time. But i think there has been this disconnect between what were hearing from the administration and peoples at the highest level of the scientific community. Let me just say as well, this 15th patient, the one that we were just talking about in california who was in the Community Acquired this virus, is in the hospital quite ill. If were saying she got this in the community, that definitely means that there are other people in the community who have it. Thats where she got it from. So then when we say theres 60 people in the United States who have a confirmed diagnosis, that number becomes kind of meaningless because clearly theres more people with this infection. And i think part of the issue, john, is that we have been really inadequately testing in this country for several weeks. I mean, koreas been testing thousands of patients a day. Weve tested not even a thousand patients over several weeks. Surveillance is the primary pillar of Public Health. If you dont know what youre dealing with, how can you possibly deal with it . And testing is at the forefront of that. I think we just havent done enough. You talk to some of my sources who have been, you know, working on pandemics, various other outbreaks in the years. They say were probably in the bottom tier of the world when it comes to testing right now. Not where you want to be. In terms of that testing, we know this is one of the issues in california with that one patient who presented symptoms apparently that doctors at the Medical Center thought they would like to test her for coronavirus. She didnt meet what was then a very narrow criteria, so it went for days before she was tested. The cdc has now revised those requirements for the test. Is that enough . Do they need to go further . And do enough Medical Centers have access to the testing . The sort of loosening up on the guidelines is an important point. This gives doctors, health care professionals, more discretion. Someone is coming in with a strange respiratory picture, pneumonia, we dont know what this is. Its not a clear cut virus or bacteria thats causing this. We should be allowed to test for coronavirus. Doctors, hospitals, theyve been asking for this for some time. But heres the issue, erica. I think this is an important point. Some of the initial testing that went out, we reported on this. They had some flaws in some of those tests, right . They couldnt be used. They were coming back as having false negatives. So those tests were pulled back. As things stand right now, theres only seven Public Health systems, three department of defense and the cdc that can test for this. To your question, right now people in california and other places around the world probably have patients in hospitals where the patients are saying, look. I wasnt in china, but i was in italy. I was in korea. I was in one of these other countries where we know the viruses are circulating. I am now sick. Can i get tested for coronavirus. What happens to me . Theyre being told you cant be tested. And by the way what happens in the interim, Health Care Workers are exposed to that person. Other people in the community are exposed to that person. I dont want this to sound overly alarmist and i always give the context. Every time weve talked about this that the vast majority of people who get this infection will have minimal if any symptoms. But the idea that we the basic containment strategies, the basic Health Strategies have fallen short here. People havent reck nazed the significance of this is a problem. And i think the numbers in the United States, i think we can disregard this number 60. I dont think it means anything anymore if we havent done the testing. The number is much higher certainly in many parts of the country. I think we are waking up to this idea we have a testing deficiency for this growing crisis which is either now a pandemic or about to be. So thank you very much for being with us. Were going to talk to you again throughout the morning because this is developing so quickly here. And the w. H. O. Saying this is a delicate situation as we teeter on that pandemic turn. Also were following South Carolina this morning. A lot of talk about whether its make or break for joe biden. We have a preview for you of tomorrows primary next.

Get published now, call for your free publisher kit today we are counting down to tomorrows South Carolina primary. And with so much on the line for each of the democratic candidates, probably none more so than former Vice President joe biden who is banking on a convincing win, the big question is can he pull it off. Jessica dean is live with a preview for us. Reporter good morning. Yes, were now one day away from saturdays primary. As you mentioned, joe biden has always really said that South Carolina is the place where he was going to show his strength. Show the coalition that he could build to be the democratic nominee in 2020. A monmouth poll shows him up 20 points here in South Carolina. And look, this week has been a good week for the biden campaign. Things have definitely broken their way. All along the way, he had a strong debate performance. Hes been making his way across the state of South Carolina. As minute who was with him in New Hampshire where he lost and really came in much lower than they thought he would and now here in South Carolina, you can tell the difference in the way that crowds are responding to him. So of course looking for a solid, convincing lead, that his campaign then hopes boomerangs him into super tuesday where he could do well all across so many states that will be voting with so many delegates up for grabs. Hoping to really slow down Bernie Sanders delegates. Remember we are so close to tuesday and super tuesday and candid
