Skyrocket. Plus, britain prepares for its peak number of cases, turning a Conference Center in london into a makeshift hospital. We will take you inside. And we begin in new york. The eye of the Coronavirus Crisis in the United States. There are over 41,000 positive cases in the city, and there were at least 830 new deaths reported on tuesday in the United States, and these are mindblowing numbers. But even more staggering are these images from around the country Field Hospitals springing up in new york, miami, and detroit, rows and rows of hospital beds to keep up with the everincreasing number of coronavirus patients coming in every single day. President donald trump struck a somber tone after a top u. S. Health expert said there is no magic bullet, no vaccine for this virus. The peak is over the next two weeks, and this is tracking mortality. So, the number of fatalities from this virus. And so, thats the part that we think we can still blunt through the superb medical care that every client is receiving, but also even more stringent, people following the guideline. A lot of people have said, a lot of people have thought about it ride it out. Dont do anything, just ride it out, and think of it as the flu. But its not the flu. Its vicious. What a contrast from mr. Trumps tweet just a few weeks ago when he compared the coronavirus to the common flu, tweeting, nothing is shut down. Life and the economy go on. Well, now President Trump is asking people to start Wearing Masks or scarves if they go out, although 80 of americans are under some form of stayathome orders until the end of the month. And hospitals around the country are struggling as they are short of lifesaving supplies to treat coronavirus patients. Our erica hill has that report.

We are still in a very difficult situation. We hope, and i believe it will happen, that we may start seeing a turnaround, but we havent seen it yet. Were just pushing on the mitigation to hope that we do see that turnaround. Reporter as beds, staff, and supplies run low, there are new concerns about the impact on care.

Meantime, here in new york city, the mayor announcing today an additional 250 ambulances and 500 emts and paramedics being sent to the city to help deal with the massive influx of 911 calls. Back to you. Thanks so much, erica hill with that report. Well, doctors and nurses in washington state, where the coronavirus was first detected in the u. S. , are adapting to a new reality in how they treat patients with the disease. Cnns sara sidner takes us inside one hospital completely revamped to battle covid19. Reporter Harborview Medical Center here in seattle is believed to be the first hospital in america to have a patient die of covid19. That was more than a month ago. And since then, everything has changed. Its changed how it runs. Reporter nurses and doctors at Harborview Medical Center suit up. To go to battle with coronavirus, they have to go through an exhaustive dressing regimen hoods and tubes and masks and gowns, just to enter a patients room. We think the greatest risk, actually, for Health Care Workers, is when they remove things, that they contaminate themselves. Reporter they have a checklist and a spotter helping with every step. They also have to adapt to new realities and shortages. So, these are what i call papper hoods. These are the hoods that hook up to these machines that filter air. And thats the hose that hooks up to the back of the hood. They do get cleaned inside and out so they can be used, because the way they were built was for onetime use, but thats not the way if we did that, we would already be out of them. Reporter wow. They have completely revamped two intensive care units. So, this whole unit was meant to be for people with brain injuries and strokes and so forth. So, now we have to move all them someplace else because we have to continue that care. Reporter so, all the people with brain injuries were moved and this was turned into a covid19 icu unit . Correct. Reporter all to try and help coronavirus patients live, isolate them from others, and keep the staff safe, too. Reporter so, i am not wearing the full personal Protection Equipment because in these rooms where the actual covid19 patients are, these are considered negative pressure rooms. That means that we are considered in a safe space not wearing full personal protection. Patients are being cared for, but we dont need to wear the full apparatus, unless you are a doctor or nurse who has to go into the room to care for the patient. Inside the rooms, patients are hooked up to a shocking number of tubes, using those precious ventilators, the only thing keeping them breathing. So, for the icu patients, they get very sick and stay sick long, so they need to require the ventilator for weeks at a time, and thats really the big issue. Reporter across just their four hospitals, 60 coronavirus patients were hospitalized last week. Already this week, its at least 100. For each one, a delicate dance to keep staff healthy and patients alive. It is just coming in here and seeing the work thats being done and seeing the patients being cared for, its stressful. Its im scared for their families as well. And so, as you walk through and you see the hard work being done and people doing everything they need to take care of patients, its aweinspiring, considering the fact that they, too, could be putting themselves in harms way. Outside the hospital, a large tent has been erected to assess and test potential coronavirus patients, and this is happening before the anticipated surge here. I feel dread and i feel fear, and im not working on the front line. What are you feeling as youre dealing with all these covid19 patients . It certainly is a sense of anxiety, because we, right now, were kind of wondering what its going to be like when that peak comes and when people are, you know, flooding in. Reporter while the number of new infections in washington seems to be slowing down, theres a growing sense they havent seen the worst of it yet. What they do every day is heroic. Going and taking care of patients without protection is not acceptable. Reporter the surge everyone is worried about is expected to happen here on april 19th, and all of the hospitals in this region are hoping theyre prepared. Sara sidner, cnn, seattle, washington. And last hour, i spoke to anthony costello, professor of Global Health at University College london, and we discussed how mass testing can be done more efficiently. What were seeing in the United States, the largest number of cases of any country across the globe and its having problems getting tests done, isnt it . We heard tuesday that theres some confusion with which labs to be used. Apparently, the federal government has sent out these tests, but theyre not going any further. So, clearly, if the United States cant get organized on any level of testing here, never mind mass testing, how would any other nation get this organized . Well, yeah. I mean, the problem that the United States faced was a bit like britain, theyve overcentralized the Testing Process initially. And in addition, you had a faulty test, where they couldnt roll it out in any way quick enough and the infection spread to many states in the country without people knowing about it. So, like italy, spain, and elsewhere, u. S. Is specifically trying to catch up. Youve hugely wrapped up testing in the last week or two, but its going to be a very big challenge for the United States to get this back under control. In the uk, its been kept rather under control by whats called Public Health england, and there is criticism that they havent wrapped this up to all of the laboratories around the country where they could have done it. The government are saying that they are having problems accessing, you know, the chemicals required for these tests. But back in januaryearly february, the Strategic Committee apparently decided that they wouldnt have the capacity to do largescale testing, and so, the mathematical multiples didnt actually evaluate that as a strategy, which i think was a mistake. I mean, its all confounding, isnt it . Because meantime, doctors and nurses on the front line are there begging, sometimes sobbing, for more personal protective equipment to help them save the lives of their patients. President trump tells us hes sending this protective gear to hospitals, but thats not what medical professionals are telling us. So, how is it possible that western nations that were supposed to be poised and ready for a possible flu pandemic are not ready for this . In any way, it seems, in terms of protective gear, testing people, ventilators. I mean, its sort of laid them bare, hasnt it . It certainly has. And i believe that in the u. S. , the pandemic Surveillance Team was disbanded a couple of years ago. In the United Kingdom, it seems to have been a strategic issue early on to simply delay the epidemic, not try to suppress it. But with protective equipment, we are having the same problems, that were not even at a testing level that enables us to simply protect health workers. And i think that is a huge failing. And of course, well have to look at all of the measures. I mean, the only defense, i guess, is that this is the worst pandemic, really, for 100 years. But nonetheless, weve had warning signs from sars, from mers, from swine fever, that we should be prepared for this. And i mean, bill gates talked only about three years ago on a wellknown ted talk that this was coming and that we had to be prepared. And sadly, the western states havent. Just one other thing is that the other group in the states and lowincome economy its simply beyond their resources. They cant really do social distancing. Theyre not going to be able to do testing. They wont have anything like the protective equipment and ventilators. So, were facing a potential catastrophe, and the knockon effects on the economy in Subsaharan Africa south asia. That was anthony costello, professor of Global Health at University College london, talking to me last hour. And then there is this the pentagon confirming tuesday it hasnt shipped out a single ventilator because it hasnt been told where theyll go. Thats despite promising to distribute up to 2,000 of them. A defense official also saying only 1. 5 million n95 masks have been sent out and it is unclear if the military has tested civilians, all contradicting what defense secretary mark esper said two weeks ago. Take a listen. First, the department of defense will make available up to 5 million n95 respirator masks and other personal protective equipment from our own Strategic Reserves to the department of health and Human Services for distribution. Next, we are prepared to distribute to hhs up to 2,000 deployable ventilators for use as needed. Third, the department has made our 14 certified coronavirus testing labs available to test nondod personnel as well, and we will soon offer two additional labs for that purpose. And a u. S. Navy Aircraft Carrier has now been hit by a covid19 outbreak. Cnns ivan watson is covering this live for us from hong kong. Good to see you, ivan. This is very disturbing. Whats the latest information you have on this . Reporter this is pretty remarkable. You have the uss theodore roosevelt, a nuclearpowered Aircraft Carrier with a crew of more than 4,000 sailors on board, with a coronavirus outbreak. So, its captain wrote a letter that was published earlier this week in the San Francisco chronicle, initially, calling for the complete, almost complete evacuation of this Aircraft Carrier after the number of Coronavirus Infections suddenly surged there in about a week from less than a dozen to suddenly more than 70 suspected cases on board that Aircraft Carrier. Now, it docked at the u. S. Island of guam last week, and now the governor of guam as well as the u. S. Admiral there have announced that they are putting together a plan to begin to move sailors off of that ship. The plan that was proposed by the captain initially was for at least 10 to remain on board to run things like the Nuclear Reactor and to ensure the safety and security of the Aircraft Carrier. And now, the civilian and military authorities are trying to come up with a way to move potentially thousands of sailors to a number of Tourist Hotels on the island where the navy has said they would be monitored and kept in quarantine by basically naval or marine police. There, of course, is concern amid the civilian population on guam, and this is an island with a population of about 170,000 people. There are some major u. S. Military installations there with perhaps 12,00015,000 personnel there with concerns as that island struggles with the outbreak and deaths as a result of coronavirus. What is the impact going to be if potentially thousands of sailors coming on shore, any number of which could be infected . The navy is ensuring that only sailors that have tested negative for coronavirus would be put into 14day quarantines in these hotels on the island, but this is still a plan that is being worked out. The military have announced that theyre sending 40 medical personnel from the marines to guam to help with this rather remarkable plan that is now starting to get under way, which is, again, to try to evacuate the bulk of the sailors from this Aircraft Carrier and then try to disinfect it somehow. Meanwhile, pentagon officials have told cnn that at least one other u. S. Navy Aircraft Carrier, the ronald reagan, has detected cases of coronavirus. Rosemary. It is a big concern. Ivan watson bringing us the very latest on that from hong kong. Many thanks. You are watching cnn newsroom. U. S. Stock futures react after the dow closes out its worst First Quarter in history.
