i want to bring in cnn medical correspondent elizabeth cohen. do we know what's holding up these results? >> anderson, it is such a mystery. governor cuomo told us that the preliminary results would be made available on monday, several days ago, but still, no word. coronavirus patients desperate for a cure, awaiting the results of studies on several drugs so they'll know which could work, including this one, hydroxychloroquine. one of the biggest studies so far at the university of albany in new york, but there's a mystery about that study. hydroxychloroquine has been heavily politicized. president trump is the cheerleader for it. >> we're having some very good things happening with it. it will be wonderful. it will be so beautiful. it will be a gift from heaven if it works. >> reporter: doctors say it needs to be studied first. on april 12st, governor cuomo gave a date to expect preliminary results sponsored by the state. >> i think we'll get actual reports on april 20th. >> preliminary results on april 20th. >> april 20th came and no prelimina

let's begin there with our senior medical correspondent elizabeth cohen. we'll get to that study on hydroxychloroquine in a minute. let's start with the news out of california that deaths from covid-19 in the u.s. were three weeks earlier than previously thought. >> yes, this is very interesting. this is something that i and other reporters brought up at the time. how do we know that people aren't dying of coronavirus? this was sort of in -- during pretty much the month of february because it was a bad flu season. i remember asking a federal official how do we know that all of these deaths from flu aren't actually some of them aren't coronavirus? i didn't get a very satisfactory answer. but to get to what the new york times reported, they found that in santa clara county, northern california, there were autopsies of two people who died in february, before the first known u.s. death who died actually of coronavirus. who had coronavirus when they looked at the autopsy. and the death -- the first known death in the u.s. wasn't until later. this is really sign

with me now, i have sanjay is back, elizabeth cohen. sanjay gupta's back, elizabeth cohen and dr. kathleen nuzle is with us, with the center for vaccine development and global health at the university of maryland school of medicine, currently working on two coronavirus therapies, one of which could become a potential vaccine. vaccine separate from remdesi r remdesivir. sanay, listen, i've been out the last couple weeks, so i'm not entirely hip on remdesivir and i'm getting caught up just like so many other people. so, this is a drug, and you're the boss, so you explain. but this is a drug that, let's say someone has coronavirus. and for me, it lasted two weeks. this is something that one could take and then it sounds like, according to dr. fauci, you just get better sooner, if you take this drug, according to this trial. is that right? >> yeah. that's right, brooke. and you know, typically, when we do think of antivirals like tamiflu, for example, it's not the same really as an antibiotic, but it can lessen the duration and lessen the severity of the disease, which is, you're abso

cdc medical correspondent elizabeth cohen joins me now with more. elizabeth, this antibody research, is it interesting or could it be a game changer? >> reporter: it's definitely interesting, john, and if it works it could be a game changer. we've heard about giving plasma. john, let's say you recovered from coronavirus. you have antibodies because you fought it off. take your antibodies, let's say i'm currently suffering, give them to me so your antibodies could help fight off the virus. that's the theory. cloning the antibodies helps because, john, you only have so much blood to give. you're not scaleable. if you clone it, those antibodies are scaleable and could help people suffering from coronavirus. that's the theory of it. here's why i'm saying theory. it might not work and also cloned antibodies could solve problems. we need to see, does it hurt? does it help? that's why we have research. it takes a while. >> they have this first wave. now what? >> reporter: right, so now it's many months. now they need to do clinical trials to see what it doe

we'll see how it goes. >> elizabeth cohen. thank you. >> governors are saying they don't have what they need for testing. we all know the shortage swabs and reagent and turn around time and chemicals coming from china. how can the cry get baountry go normal if these issues go unaddressed? >> it is a significant problem, anderson. we are hearing from governor cuomo that he's having to out bid other states and there is a lot of confusions of where to get these things. we are the united states of america and we should have a plan that works for everybody and the states are coordinating. this is a big problem here. until we have a national strategy and everybody is working together for a good supply chain, we are going to have problems here >> one of the problems, the president talks about america first but this is a very, the supply chain is international. a lot of chemicals come from china and a lot of pharmaceutical drugs come from china which there are increasing concerns of shortages of. while the president is going after chi

hotez also i want to bring in our elizabeth cohen. i understand you have new data on just what impact orders stay-at-home had on the nation's hardest hit cities including new york and new orleans. >> right, this is really interesting. this is literally just published seconds ago. they looked at four different cities and they found that when stay-at-home orders were issued, that people did to a great extent pay attention. they found mobility in those cities went down by about 20% to 40%. they counted mobility of people staying at home. 20% or 30% of the people literally stayed at home and did not go anywhere. they can tell by tracking their cell phone devices. that's telling us these orders for social distancing really are working and hopefully it will flatten the curve and it will help slow the spread of this virus. >> elizabeth, i want to go back to dr. hotez. what do you make of that sort of confirms obviously what others have been saying. >> well, it means people get it. people will do social distancing and there are some app data

our medical correspondent elizabeth cohen joins us now. elizabeth, how helpful is this drug for treating people with coronavirus? >> reporter: wolf, we just don't know. doctors at the university of chicago are studying remdesivir, and they were heard saying it works really well. what you didn't hear is what i'll total you right now, is the study they're talking about was paid for by gilead, the company that makes the drug. the other thing you didn't hear was that there are plenty of patients doing just fine not on remdesivir. this is a doctor who is treating patients with remdesivir. >> wea've had a lot of patients improving and going home. it's hard to know if that's due to the study drug or not. we're expecting results later this month. >> reporter: now, i was speaking to a doctor at harvard, she works at mass general hospital. she said, look, elizabeth, have i had patients who have done well on remdesivir, absolutely. but have i had patients who have done well without it? absolutely. when you have those kinds of comments, you know that w

elizabeth cohen is here with us. >> we heard kaitlan talked about. these antibodies, if you have been infected, you are immune. they need to be out there on a wide scale and they need to be tested accurate. >> with the country shutting down. one thing that could help it bring it back to life is this test. it tells you whether you have covid-19 and developed antibodies. if so, you can be immune. >> these are the tests that we know are critical for the future. >> on wednesday, the second and third antibody tests for the united states that's helpful for doctors and nurses. >> i think really being able to tell them. the peace of mind that would come from knowing that you were infected and you have the antibody and you are safe from reinfection, 99.9% of the time. i think this would be reassuring to our front line healthcare workers. the concern is getting those tests out and distributed to hospitals and doctor's offices. >> more concerns of hydroxychloroquine, a malaria drug touted by president trump to use against covid-19. >> i think it could be a game

our senior medical correspondent elizabeth cohen joins me now.the test work, what are the concerns? >> let's talk about the basics of this test, anderson. it looks to be if you've been infected in the past. not presently, but the past. it can help you and your employer to decide, can you go back to work now? is it safe? are you immune? here's the issue. you mentioned correctly there's only one fda approved test for this but dozens of others that don't have fda approval and i know this is confusing but still allowed to sell their products in the united states. so i was talking to an association of labs and these companies saying to the labs, use our test, use our test and this association is saying, huh-uh. we can't use it because your test look in the words of the head of their association, crappy, that's the word he used. he's afraid they're going to give inaccurate results. >> why are tests that are potentially inaccurate or crappy in this person's words, allowed to be sold? isn't that misleading? >> it's because these are very strange times an

cnn's elizabeth cohen, though, she's been looking at these. beth, we're hearing a lot more about one particular drug this morning, recommemdesivir. what more can you tell us about the trials? >> doctors were caught talking on a video about how this drug looks promising but it's just chatter. we'll need a lot more testing for this drug, plus others, before we can say they work to treat covid patients. to seems to be president trump's favorite drug. >> i think it could be something really incredible. >> reporter: it's e hydroxychloroquine and early studies suggest it might not work and could cause heart problems. the food and drug administration told the "washington post" that he doesn't feel political pressure to make this drug work for covid-19. >> i can promise the american people that the fda will use testing to drive these decisions always. >> reporter: and there are other drugs to see if they might work against the coronavirus. on thursday, just one day, nearly 40 potential trials were registered here on this government list of clinical tri

cnn's senior medical correspondent elizabeth cohen joining us now with a look how some hospitals are e while they are at home. elizabeth what they are doing? >> fred, so important. because the sad reality of this yau outlake is not every patient can get a hospital bed. even those moderately ill sometimes are sent home to recover and's told what to look out for but it's not foolproof. sobering statistics in new york city. before coronavirus in new york city, 20, 25 people would die every day at home from various thing, but since covid has been happening, that's more than 200 deaths a day. official there's, they attribute that, said we think this is because of coronavirus. that huge difference is because of people recovering from home. the cleveland university health system decided to do something about this. when they send someone home, we're nort admitting you, sending you home with a device. they send them home with a device. a gentleman named leonardo frazier, a janitor in the area. he had covid, went home with this device and it is attached to a central command. that's the really i

elizabeth cohen is with us.lts or lack of effectiveness of hydroxychloroqui hydroxychloroquine. >> that's right, hydroxychloroquine you may remember is the drug that president trump has been touting calling it a game changer. this study done by veterans of doctors and found that those who took hydroxychloroquine, the drug that trump likes had more than twice the death rate compares to patients who did not take it. the study was published on the preprint website. it has not been reviewed by other physicians and not been published. hydroxychloroquine is one of this drugs that are being studied and also at the same time doctors are really trying to get antibody testings going. that's testing that can see, it is not about treatment but testing to see how may already possibly have antibodies to coronavirus and may be immune. >> antibody testings, we can't get back to normal without it. >> the antibody pieces is critical. >> it shows whether you have been infected with covid-19 and develop antibodies and may be immune

our senior medical correspondent elizabeth cohen is joining us. elizabeth, how significant are these initial results? >> reporter: they're very significant. hopefully this drug will make a difference, not only in and of itself but it is a proof of concept, allowing doctors to find other drugs that work similarly. first, let's take a step back. remdesivir is not exactly a household name. it's a drug that was invented for ebola many years ago. and what they found was it didn't actually work for ebola and it's actually never been on the market for anything. so this is still an experimental drug, you can't, you know, go to a pharmacy and find it. let's take a look at the study dr. fauci was talking about. it was 1,090 study subjects in the u.s. and several other countries. half of the people took remdesivir and half took a placebo. the people who took a placebo, it took them 15 days to recover. when people took remdesivir, they had only 11 days to recover from covid-19. you might look at that and think, it's only four days, what's the big difference he

let's bring in elizabeth cohen. what do you make of this warning when the president has been pushing hydroxychloroquine as a potential solution here? >> i think we have all been concerned, brianna, about things that the president has said about hydroxychloroquine not to mention other medical issues so i take this as a good sign that at least some of his administration is listening to the science and basically defying their boss. so the food and drug administration saying, look, hydroxychloroquine can cause heart problems, it should only be used for covid patients when it is part of a clinical trial. the national institute of health saying basically the same thing. so they're telling doctors, look, the benefits of this are -- doesn't look like it is going to outweigh the risks so be very careful. >> and, elizabeth, i know you're tracking news on a potential step forward in the treatment of the novel coronavirus. there are chinese researchers who say they successfully cloned the antibodies of patients who have recover

cnn's elizabeth cohen joins us now with more. elizabeth, so how do doctors and nurses make that call? this is a difficult call, and for some patients it's a life or death call. >> absolutely, jim. what i'm hearing from doctors is sometimes there is a very blurry line about what needs to happen now and what can be put off. one surgeon in new york city saying he's had to make decisions that he's never had to make before. this is a surgeon who operates on tiny babies. and these decisions are being made and contemplated not just in new york city but in other places in the country. >> reporter: marley baxter was born with half a heart and had three open heart surgeries before her second birthday. >> oh, i love that smile so much. yes, i do, so much! >> reporter: today marley is three years old, and recently her mom, jolene, realized she's not getting enough oxygen. this number is very low. marley's doctors ordered a heart catheterization to figure out what's wrong. has she had that heart catheterization? >> no, she has not. the hospita

elizabeth cohen has the latest. >> antibody testing to check for past infection.fficials said these tests are critical to reopening the economy. but there are concerns many of them don't work very well. >> the problem is that these are tests that need to be validated and calibrated. and many of the tests out there don't do that. >> scientists in california, includi decided to see how they're working. several had frequent false positives. one more than 15% of the time. three others, false positives more than 10% of the time or more. one of the researchers calling these results really terrible. last month, the u.s. food and drug administration relaxed their standards for these tests allowing them them to be sold without submitting any data that they work. the fda and other agencies have been saying they'll figure out which tests work best. but the fda telling cnn they have nothing to sharon this effort. while scientists try to work it out, doctors at texas a&m announcing they're going to start a clinical trial of a 100-year-old tuberculosis vaccine and hope it works

cnn's elizabeth cohen spoke to a nurse in new york who couldn't get tested and worked for nearly a week while infected. >> reporter: this nurse says she worked for about seven days at two new york city hospitals while infected with the coronavirus. she went undetected because her hospital wasn't testing the staff. she doesn't want to reveal her name or where she works for fear she'll be fired. >> two weeks ago i was feeling back pain, a lot of back pain and then one night i had really bad chest pain. >> reporter: did you ask your hospital to test you? >> i was told the hospital was not testing staff, that's what i was told when i asked about getting tested. >> reporter: she continued to work. you wore the same mask the entire day from patient to patient to patient? >> yes. yes, we do. i'm touching that mask. it's on my face. i'm putting it back on. virus flies in the air, it goes right up in my nose. it's so easy to get contaminated when you have to put something on that already has virus on it. >> reporter: you wore the same gown all day from patient to patient to patient? >> yes, the

let's get an update from our medical correspondent elizabeth cohen, who joins us. s why antibody testing, elizabeth, is so critical. >> reporter: right, so antibody testing is not a test that tells you if you currently have covid. it's the test that tells you, hey, you had it sometime in the past, and you recovered, and your antibodies are present because they fought that disease off. this is super important to know, wolf. from both a personal and sort of a public health level. on a personal level, if you know you have antibodies and if it means you're immune to covid, it could mean you could go back to work and sort of reenter society. on a larger level, if enough people have antibodies and if it means they're immune, it means we could start opening things back up again. but there are several big problems with the antibody tests. first of all, there's a lot of them out there that aren't good. the fda loosened the rules and allowed all of these tests out there that simply don't work. so that's a problem. secondly, the tests need certain chemicals and other ingredien

elizabeth cohen, cnn reporting. >>> okay. back with us now, dr. colleen kraft and dr.-- at holy n medical center. great to have both of you. >> i know we're getting ahead of ourselves. the clinical trials are just beginning, not at the end of them. but doctor, people are desperate for hope each if they can't get their hands on it today. also the new developments that you heard and what you're seeing around you, is there a reason to think that some of these could be promising? >> i think we all need encouragement. full disclosure, i'm involved in my own clinical trials. i would urge caution. the reason being is this. a lot of the initial discoveries and medications are retrospective or observational. it's hard to make long squeaking definitive claims when you're looking at charts and say gee, they took this medicine, seemed to get better. you can't ascertain whether it's a causative effect. let people have control group where they get pla seeb open and patients get a study drug and move forward prospectively in time before we make a claim. this is the first pandemic in

let's go to elizabeth cohen in atlanta. izabeth, take us inside what was said and why it matters. >> reporter: let's go to the survey or modeling found. this is according to the "new york times." on march 1st, if you look all the way at the left at that tiny little bar, according to the cdc, there were 23 cases. nearly all of those were people who had traveled to wuhan. what this model says is, look, when we look backwards at what was going on, our model our, ou estimate, our guess is that in boston and seattle each there were 21 cases, seattle 3100, san francisco 9300 and new york 10,700. this is a model, right, john, and you and i have talked about models before, they are educated guesses. looking at what we know now, this is what they think happened. again, this is march 1st. according to the cdc, the first case of transmission, in other words, not a traveler to wuhan coming back and getting his wife sick, but getting sick out in the community was february 26th. so this does not mesh at all with what the cdc says. what th

let's bring in senior medical correspondent elizabeth cohen. on developing an actual vaccine, how long 'til people can be vaccinated, elizabeth? >> reporter: wolf, it takes time, you have to figure out if it's safe and effective. dr. fauci and others are saying there's a 12 to 18-month effort at the very least. but last night a leading vaccine expert at the national institutes of health telling cnn she thinks it can happen more quickly. >> we're talking about for emergency use, that would be for health care workers and people who might be in constant contact and at risk of being exposed over and over. then for the general population our target goal is for next spring. >> reporter: now, dr. corbett says they can do it quickly partly because the nih was ready to, as she put it, aim and shoot. they knew a pandemic would be coming at some point and they set up an infrastructure to make the vaccine happen quickly. we've reached out to vaccine experts who are skeptical that it could really be ready to give to people by the fall. >> elizabeth, once a

here's cnn's senior medical correspondent elizabeth cohen. >> reporter: across the state of new york,alth officials arranging for blood tests to try to answer this question -- how many new yorkers have already had novel coronavirus? it's called antibody testing. >> they had the virus. they developed the antibodies. and they are now quote/unquote recovered. >> reporter: if someone has antibodies, it's possible they are immune to the coronavirus. if enough people are immune, the economy could start the process of safely opening back up again. thursday, governor andrew cuomo announcing that the state has done 3,000 antibody tests, but it's not going as fast as anyone would like. >> we're getting better and better at it as the weeks go by, but we are not in a situation where we say we're exactly where we want to be with regard to testing. >> reporter: part of the problem? the u.s. food and drug administration relaxed its rules and allowed dozens of companies to sell tests without first proving that they can get accurate results. so it's hard to know which tests will work. just four have b

elizabeth cohen ex mains. >> coronavirus patients desperate for a cure. including this one.of the biggest studies so far at the university in albany in new york. but there's a mystery about that study. hydroxychloroquine has been heavily politicized. president trump is the cheerleader for you. >> we're having some very good things happening with it. it will be wonderful and so beautiful. it will be a gift from heaven if it works. >> but doctors say it needs to be studied first. on april 12th, new york governor andrew cuomo gave a date to expect preliminary results from the albany study being sponsored by the state. >> i think we're going to get actual reports on april 20th. >> we'll get preliminary results on april 20th. >> but april 20th came and no preliminary results. the next day cuomo was asked about it again after he visited the white house. >> do you have any indication what the state results have been? you said they were being sent to washington yesterday. >> i have no -- i do not know. i do not know. >> the researchers say he'll be releasing final results as early a

elizabeth cohen, thanks very much. >>> still to come, the fate of the u.s. economy. the dire warning from a top white house economic adviser who says we are facing jobless numbers not seen in this country since the great depression. >>> plus the crucial role of contact tracing. we're going to speak to an expert about why it's so important. this is, of course, discussing people who have been infected and who they've had contact with. it's not easy. we've worked to provide you with the financial strength, stability, and online tools you need. and now it's no different. because helping you through this crisis is what we're made for. hey allergy muddlers... achoo! ...do your sneezes turn heads? try zyrtec... ...it starts working hard at hour one... and works twice as hard when you take it again the next day. zyrtec muddle no more. >>> so this morning a new model showing the predicted u.s. deaths is actually higher than it was just a week or so ago. dr. chris murray at the university of washington says this toll could hit 74,000 by august. listen to this. >> do you think

cnn's senior medical correspondent elizabeth cohen is following new developments in testing and treatmentsnd filed this report. >> reporter: antibody testing. we can't get back to normal without it. >> the antibody piece is critical. >> reporter: these tests show whether you've already been infected with covid-19, have developed antibodies and might be immune. but this week, we are learning there are several problems. one, some of the tests don't work. >> the problem is that these are tests that need to be validated and calibrated, and many of the tests out there don't do that. >> reporter: two, the test needs certain materials to make them work, and many officials say there's just not enough of these supplies. >> those labs can only run as many tests as the national manufacturers provide them chemicals, reagents, and lab kits. the national manufacturers say there are supply chain issues. i'd like the federal government to help on those supply chain issues. >> reporter: three -- even if you have antibodies, it's not clear what that means. >> there's an assumption, a reasonable assumption,

. >>> let's bring in elizabeth cohen. so the white house has been looking at antibody testing in particular as a gateway to getting the country back on its feet. but there is a question about this test, is there not, because the key question is does having antibodies, in other words having exposure to this, necessarily give you immunity to coronavirus? >> right, that's the $64 question as the scientists put it know. the white house's own scientists are telling the white house there are a lot of issues with antibody testing. it would be great if it worked well, jim. the reason for that is you could give antibody tests to large numbers of people and you would get sort of a feeling for who has antibodies and who might be immune. but there are so many roadblocks to that. first of all, the fda loosened the standards, so now you don't have to show your test works in order to sell it. you can pretty much say to the fda, i'm selling a test and i'm not going to tell you if it works or not, i won't show you the data that tells you

. >> all right, first, let's get more on this study, elizabeth cohen is with us. i thought we couldn't get more sort of jaw dropping than the headlines yesterday. and this is far beyond that. >> right. absolutely. and this is, i think this is -- this is something that we need to remember. this is something that many of us were asking folks, federal officials very early on, hey, is it possible that this is spreading more than what we think? i know i talked to one very prominent federal official and he said, no, i don't think that's the case. but let's take a look at this. let's take a look at what the new york times found when it spoke to modelers at northeastern university. they thought that there were maybe 20 something cases in the entire country, around march 1st. what they found is in boston alone there might have been 2300 cases in seattle also 2300 cases, in chicago, 3300, san francisco, 9300, new york, 10,700. in other words, the cdc and other federal officials did not recognize that it was already spreading, if this modeling is correct. >> elizabeth, can i

let's begin with elizabeth cohen on this experimental vaccine. what do we know? >> at this point, they are all experimental vaccines. so we any that pfizer has teamed up with a german company, and there is lots of that going on. you have a big pharmaceutical team teaming up with a smaller group, that's been happening all over. so this now puts it in the same category as some other ones that we have been talking about. there are seven now in human clinical trials, the first one would have started its human trials back in march. they have been coming since then. we now know of about five with specific dates. so this puts pfizer somewhere around number four as far as when they started in human clinical trials. the bottom line here is that this is good. it is good that these companies are moving so quickly. it is good that they are already in human clinical trials, i think i've been told this is moving with unprecedented speed, no one has seen a vaccine trial move this quickly. i should say vaccine trials. but we shouldn't expect to see this vaccine anytime soon. eve
