hello and welcome to our viewers joining us here in the united states and all around the world. you're watchi ing "cnn newsroom and i'm michael holmes. coming up this hour. >> i think it's a great thing to wear a mask. i've never been against masks, but i believe they have a time and a place. >> president trump finally seen publicly wearing a face mask. this, as coronavirus cases skyrocket in the u.s. also covid-19 surging through brazil. the country has seen nearly 40,000 new cases and more than

1,000 deaths from the virus in one day alone. and back to school. we'll hear from two teachers who just lost their colleague to the virus. like many, they're questioning if they can't keep themselves safe, how can they keep the kids safe? president trump now doing what some americans have been doing since the month of march, wearing a mask. during a visit to a military medical center on saturday in the president's case, this is the first time he's been wearing one of these in front of the cameras. doctors and scientists have been saying for months that wearing a mask keeps the virus from spreading, even if you don't know you have it. in fact, there's a new estimate now of how many people may be infected with coronavirus while having no symptoms at all. the cdc says it could be as much

as 40%. the cdc also estimates that about half of the time, the virus is transmitted before people get sick. it might be one of the many reasons that explains this. 29 states now reporting a rise in coronavirus cases. south carolina, texas, florida and georgia all reporting record or near record daily case numbers on saturday. well, now that hospitalizations are catching up with soaring new case numbers, experts are sounding the alarm. this week, the number of lives lost to covid-19 was about 800 for four days in a row. so far, there have been almost 135,000 deaths nationwide. now, again, this is the first time the u.s. president has worn a mask on camera during the coronavirus outbreak. he's refused for months, despite the urging of his own team of public health experts. kristen holmes now explains why

he decided to do it now and whether he'll stick with it. >> reporter: president trump wearing a mask for the fist time in public saturday on a visit to walter reed hospital. there, he met with wounded warriors, as well as health care workers on the front lines. and we have learned this was a result of begging and pleading by aides and advisers who wanted him to have this photo-op in a mask to make a point. to endorse mask-wearing. however, there are some quest n questions as to whether or not this will actually work. we have to keep in mind, wearing a mask has become incredibly policical. and president trump made a statement on the way to walter reed about why he was wearing a mask at this point. take a listen. >> well, i'll probably have a mask, if you must know, i mean, i'll probably have a mask. i think when you're in a hospital, especially in that particular setting, where you're talking to a lot of soldiers and people that, in some cases, just got off the operating tables, i think it's a great thing to wear

a mask. i've never been against masks, but i do believe they have a time and a place. >> reporter: so, you hear the president there giving a very limited setting. he's talking about soldiers coming off of the operating tables. and that is not the same message that these health officials are setting. they are saying to wear a mask any time that you cannot socially distance. they want people wearing masks indoors, they're talking about people wearing masks at grocery stores. and it's unclear that this is going to send the message that his aides and advisers were hoping it would when he's limited it to such a very small venue of when he believed wearing a mask is appropriate. and just to remind our viewers, this is something that president trump has really been against. he says he hasn't been, but he's said he didn't believe wearing a mask was for him. we know behind closed doors he said if he was seen wearing a mask, it might send the wrong message to his supporters as he's trying to move away from the virus. so, whether or not this works,

whether or not we even see president trump in a mask again, the likelihood of him going to another hospital to visit wounded warriors, that really just remains, at this point, unclear. kristen holmes, cnn, the white house. >> and with me now to clarify some of the latest findings about the virus, doctor, i wanted to ask you about, you know, we hear about the tragic cases of those who died, what they went through and horrible as that is, but there seems to be growing evidence of long-term damage to those who survive this. what are you seeing? >> well, thank you for having me, michael. yes. as the pandemic is now in its fifth month, we're starting to see patients coming back who have actually recovered from the initial illness and, yes, they're having a lot of lingering symptoms. these are patients who have been

confirmed covid positive, tested negative, have some sort of immunity in their blood and now they have persistent symptoms such as fatigue, some neurological symptoms, some difficulty breathing. so, yes, i am seeing more of it, talking to my colleagues and even in my own practice. >> what has surprised you most in terms of what you're seeing in those who have quote unquote recov recovered? what sort of things would you not have expected to be seeing? >> i really would not expect to see such lingering shortness of breath, especially with light amounts of activity. i really did not expect to see this generalized weakness and fatigue. weeks, even a month after the infection had resolved. >> is it surprising how apparently broad the damage can be? i mean, not only the lungs, we're hearing kidney damage, liver, heart, brain, nervous system, gastrointestinal. all of these things were noted friday in a review of reports

about covid patients. i mean, a very broad range of damage. >> yeah, i think the medical community, when the pandemic initially started, was kind of modeling it after an influenza infection, so, primarily lung infections, but unfortunately, we're getting a lot of data from autopsies from the casualties of this pandemic and what it's showing is that, you know, people are dying of systemic inflammation, systemic blood clots. it's a much more ubiquitous infection than, say, a traditional flu. >> yeah, the blood clotting, in lots of organs, as well. our own chris cuomo and richard quest, who had the virus, of course, they've spoken about things like balance and brain fog and so on. what are you seeing in terms of neurological impacts? even perhaps amount patients

that didn't havele respiratory problems? >> i read the piece that richard quest put in, and that's exactly what i'm seeing. i'm seeing a lot of patients who are having this chronic fatigue, can't quite get their breath, even with very light amounts of activity. generalized weakness. kind of a malaise feeling that just does not go away. and sure enough, the pandemic is still pretty young, we're only in its fifth month, so, we don't know if multisymptoms will eventually recover down the road, but yeah, that's exactly what i'm seeing. >> yeah, and you touched on this, i mean, we obviously want to show you how much we don't know, i mean, we have a lot to learn, as we say. what would you like to see done in terms of getting our hands around the wider impacts of the virus and those lingering effects going forward? what sort of 23450eneeds to be o study that and sort of get our heads around it?

>> yeah, i mean, now that we're getting a lot of data, both here in the united states and around the world, i think the -- we should really focus on creating an international database, the kind -- classifying these patients so we can get better targeted treatment for people who are infected. i don't think we have enough of an international cooperative database to start looking at these large volumes of patients that we have the benefit of studying now. >> i want to touch on this, too, seeing reports already of people uninsured or underinsured getting some massive treatment bills, given that the u.s. doesn't have universal health care. are you seeing stuff like that? what could we see in terms of the financial impact on people, post-treatment or with ongoing treatment needs? i mean, the u.s. system isn't kind to people who aren't insured and the unemployment issue has only added to that. >> yeah, i'm starting to see quite a few patients now who have ended up losing their jobs

and losing their health insurance. i think -- it effected the patients who had critical illness the most, people who have been on ventilators for weeks to a month. they're going home -- they've recovered, they're going home and they're being hit with these very large bills. so, i really don't see that changing until congress startles addressing that particular focus of population to try to help them. >> and just finally, what are you seeing regarding noncovid emergencies? i guess in terms people perhaps not seeking medical treatment when they should because they're worried about covid and those with other conditions, heart or whatever, perhaps having to wait to be seen? is that a problem? >> well, when the pandemic first started, we definitely had to put off a lot of these elective procedures, so, fortunately, most of them were not criteria came. as far as the critical cases, people were initially afraid to

come into the hospital in case they contracted covid, so they were putting off symptoms, you know, related to heart attacks, strokes, they just weren't coming in. and by the time they just couldn't tolerate the symptoms anymore and came in, much of the damage was irreversible, so, we have education programs in our system to make sure patients are vigilant about some of these symptoms and to not stay away from the hospitals, you know, we have a lot of protections in place now, we're much better with protection to patients that are coming into the hospital. and we're better at treating, you know, covid at this point. >> right. right. much to learn, much to be rn canned about. dr. jacob stephen, thank you so much. >> thank you, michael. well, the coronavirus also raging through latin america and the caribbean. brazil, the second-worst affected country in the world, after the united states, of course. it reported more than 39,000 new

cases on saturday, bringing the total past 1.8 million for that country. and the country these most high profile patient is the president, jair bolsonaro, who is touting a controversial drug. cnn's bill weir is in brazil, he has the latest. >> reporter: here in brazil, that covid-19 curve continues to go completely in the wrong direction, averaging over 1,000 deaths a day. now, over 1.8 million confirmed cases, but with a lack of testing all across this vast country, a lot of experts believe that number's off by at least a factor of five or ten. meanwhile, president jair boll son the bolsonaro, the most famous covid patient, continues to promote his hydroxychloroqui hydroxychloroquine, the ant anti-malaria drug that he's so fond of. i'm in the center of brazil today, a big agricultural

region, where i met a doctor who spent ten days in intensive care. now, his boss, the supervisor of his hospital, is in intensive care. i asked him about boll son their rope's prescription, he said, he took those anti-malaria drugs and they did not work at all for him and yet he prescribes them because he has no other choice. they're cheap, they're available. otherwise, what do i give my patients, water? he also said that for a lot of patients in this rural agricultural area, the other choice to infection is poverty or starvation. and so, it doesn't take much encouragement from the man in charge for people to get back to work, for people to heed that call. so, that comes down then to the only way to protect themselves, to try to flatten this curve here, is mask-wearing, social distancing, quarantines. we know the president's not fond of that. and the president, even though he was ordered to wear a mask by a judge back in june, defied that time and time again, flew

to other states, was waving to crowds, with hugs and handshakes. we have seen him wear the mask, though he took it off the day he announced he had it. it will be interesting to see, after -- if he comes through, hopefully he comes through this, whether it will change his mind about the other precautions. his wife and daughters tested negative for covid-19. the bolsonaros, but right now, it's just, places are bracing for what may be another wave that never really went down, as more and more cases become evident all around this country. i'm bill weir, cnn, brazil. robert mueller, the former special counsel who invested the 2016 trump campaign's ties to russia, says the profession cute against roger stone was legitimate and, of course, legally, his conviction stands. roger stone, president trump's friend and political ally, was

found guilty of lying to congress and guilty of seven charges. mr. trump commuted stone's 40-month sentence on friday night. now, in a rare op-ed in "the washington post," mueller is defending his team against the white house's cries that the investigation was a hoax and a witch hunt. in his op-ed, he writes, quote, we made every decision in stone's case as in all of cases based solely on the facts and the wllaw and in accordance wit the rule of law. the women and men who conducted these investigations and prosecutions acted with the highest integrity. claims to the contrary are false. we are seeing enormous pressure from the top to get u.s. schools up and running again. within weeks. but can it be safe? i talk to two teachers who know the dangers first-hand. that's when we come back. at t-mobile, we have a plan built just for customers 55 and up.

children, in many cases, the immune system is so powerful, so strong, but the young and the healthy to safe little return to work and to school, we have to open our schools. open our schools.

stop this nonsense. we open our schools. >> well, u.s. president donald trump there in his relentless push for students to get back to the classroom. but the country's health experts don't seem to be in agreement. an internal cdc document obtained by "the new york times" warns that fully reopening schools and universities remains the highest risk for spreading the coronavirus. it's not known if the president has seen that or not. but it appears to have been distributed early this week when the president slammed the cdc school reopening guidelines. schools in arizona, one of the hardest-hit states, are struggling to determine how to reopen safely, as coronavirus cases there, of course, continue to rise. now, one school district, this is in gila county, not far from phoenix, is struggling more than

most. kimberly taught an online summer school class with two colleagues in the room there. they all followed the precautions, cleaning, distancing, wearing masks and so on, but all three contracted the coronavirus and two weeks later, kimberly died. well, now her colleagues are mourning her loss and, of course, wondering if they couldn't keep themselves safe, how are they going to keep a school full of students and teachers safe when they all go back in the autumn? byrd's fellow teachers do join me now, i'm delighted to say, jenna martinez teaches first grade, angel la skilli angela sg second grade. jenna, let's start with you. tell me a little bit about kimberly, the type of teacher, more importantly, the type of person. >> the type of person kim was was -- she was just a very faithful person and she led her

life based on her faith. she was very supportive. chef was what i would call a giver, giver of knowledge. a giver of kindness. compassionate person. a strong person who stood by her values. she was bold when she needed to speak up when there was an injustice or someone needed to be heard, especially when it came to children, her students. or her colleagues. she was fun. she was adventurous. she was just a true, loving person all the way around. and -- >> and the story is just so incredibly sad. i mean, the loss of her and now, of course, we're seeing this push for schools to reopen, the president even threatening to pull federal funding from states

that don't do what he wants them to do. given your own experiences of covid in the classroom, i'm just curious what goes through your mind, numbers soaring in many states and you've got the president saying, open up or else. angela? >> well, it's very heartbreak g heartbreaking, with what we have gone through. and my main thing is, if we can't stay safe, how are students going to stay safe? i understand we need to open up america economically, we need to get people back to a normal, but we are no longer in the normal society we've been living in. we are now going to have to switch things around, because of the virus. for our children, we have to think of their emotional states. if we bring them back to the classroom, children that like to touch things, like to share, they're socializing, what are we going to do to them emotionally if they take that virus home and

give it to a family member or a day care worker or someone that they are close to and that person passes away? we are going more emotionally that way. >> yeah, no, i understand it and it's interesting, as you were speaking, we were running some file video of kids in school rooms and it is just striking, when you think about places where cases are skyrocketing, even with with guidelines, i mean, you know, how realistic is it to imagine that you're going to be able to have distancing in corridors, mask-wearing, hygiene, when kids are being kids. >> yeah, i know in my classroom, you know, i -- last year, i had 20 students and i was lucky if they were six inches apart. i can't imagine trying to keep them six feet apart. they're constantly, you know, you have small groups, they tell you, do a lot of student grouping and how are we going to

do that in a classroom if we have to social distance? they're going to share everything. they share viruses, they share different illnesses, it's going to happen. and the mortality rate, yes, might be low, but we have to protect our youth. we have to protect our future. these are the kids that are going to lead us 30 years from now. >> you both had this. how are you now, just real briefly, jenna, you start. >> today's my best day yet, in about a month. i still have a cough. i still am taking breathing treatments to relieve the tightness in my chest. the fatigue is still lingering. and i tested negative on my retest. >> angela, you, too? and i'll just say to people, too, just before we started this interview, you were both coughing. angela, real quick, how are you? >> you know, i thought i was getting better and yesterday,

the cough came back full force. probably feeling the worst today than i have in the last month. i retested a week ago, came back positive again, so next week, i will go back and get tested again, hopefully this time it's negative and that we can push through this. >> you're both remarkable ladies, our hearts go out to you for the loss of your friend and what you've gone through. thank you for your courage, thank you for talking to us. jenna, angela, thank you so much. >> thank you. >> thank you. now, the principle of the school where byrd taught released a statement to cnn. in it, pamela gonzalez says this, quote, losing mrs. byrd in our small rural community was devastating. she was an excellent educator with a huge heart. we find comfort in knowing her story may bring awareness to the importance of keeping our school employees safe and our precious students safe in this pandemic.

we are as eager to be able to see our students in person. it has been a long wait. however, we will wait as long as we have to until we can provide the safest environment possible for our students and staff. it is our responsibility to do so. coming up here on "cnn newsroom," an update from the hard-hit state of florida. find out which way the numbers are going and what the governor has to say. also, why some tourists are still willing to book a ticket to arizona for a vacation in the middle of a pandemic hot spot. we'll be right back.

welcome back to our viewers here in the u.s. and all around the world. i'm michael holmes. you're watching "cnn newsroom." there is a new estimate of how many people may have coronavirus while showing in symptoms at all. the cdc says it could be as much as 40%. it's one of the reasons why this virus has been so hard to contain. the number of confirmed covid-19 cases worldwide is now beyond 12.6 million, according to johns hopkins university. the u.s. continues to be number one for confirmed cases and deaths. a quarter of cases and deaths. the cases in the u.s. now exceeds the population of 21 states. this week, 29 states are reporting a rise in cases, with south carolina, texas, florida and georgia all reporting record or near record daily case numbers on saturday. and the governor of hard-hit

florida says the state will not be moving onto the next phase of reopening for now. and he says he's working with the white house to get more testing capability. saturday, florida reported its third-highest daily increase in cases, more than 10,000 new infections. and officials say nearly 4,200 deaths have been recorded since the beginning of the pandemic in that one state. cnn's randi kaye has an update from florida for us. >> reporter: here in the state of florida, we are getting word that the numbers just keep going up. more than 10,360 new cases in the last 24 hours and 95 deaths in the last 24 hours here in the state of florida. we also know, finally, the number of hospitalizations here in florida, reporters have been pressing the governor's office for weeks to release those numbers of those that have covid-19 and are in the hospital. we now more than 7,200 people are hospitalized with covid here in florida. more than 560 of them are in

orange county, where orlando is, where disney world is. and more than 1,600 in hard-hit miami-dade. and the news just keeps getting worse for that miami-dade county in southern florida. that is the hardest hit county. we're getting word that 44 county bus drivers have tested positive for the coronavirus. one of them has died. it's unclear if that driver was symptomatic or what route that driver had taken. the others are quarantining at home. but the numbers just continue to jump since the state reopened on may 4th. we've seen a -- more than a 1,200% increase in the average number of daily new cases here in the state. back on may 4th, the average number was about 680. it's now more than 9,000. but the governor speaking today did say that he's going to try and get more self-swab testing in place to try and get faster results of those who may have this virus. he said that would be about 36 to 72 hours instead of several days that it's taking right now. i'm randi kaye on singer island,

florida. back to you. >> arizona's health care system now buckling under the pressure of its coronavirus surge. officials reporting more than 3,000 new cases on saturday. the state now has fewer than 1,000 hospital beds available for in-patients. and more than half of its ventilators have been in use this week. arizona has led the nation for a month with the highest seven-dale average of new cases per 100,000 people. now, despite it all, evan mcmorris santoro finds some people still see arizona as a holiday destination where they can leave their cares behind. >> reporter: this is the grand canyon. nearly a mile deep and eight to ten miles wide, depends on where you're standing. should be a great place to socially distance. but it's also the south rim of the grand canyon. one of the most important tourist destinations in all of arizona. hotels, gift shops, gathering

places. other places that officials are worried the pandemic could spread. there are new rules here about masks and socially distancing that they're hoping will keep things controlled. vacationers say it's worth the risk. >> basically because it's the safest thing to do right now during covid-19. you can still enjoy a good vacation. you're out with family, friends, still outside, great view. good times. >> reporter: what is it like to go on a vacation in the middle of this? you're coming from one hot spot to another one? >> basically everything is different, you know, normally on vacations, you're looking for the ability to go out and sit down and eat. now it's kind of like getting everything, bringing it back to your rooms and you have to wear a mask everywhere. and in this heat, that can be difficult. >> reporter: let me ask you about that mask thing. your mask is prekt direction. if you can wear this, you're too close, right? >> yes. >> reporter: i walk around here, i see some people not wearing them. what do you say about that, what do you think about what you're

seeing in terms of people doing the mask requirement? >> i mean, to each his own. i mean, me personally, i believe we have to think beyond ourselves. i'm not just wearing a mask for myself, i'm wearing it for the next person. and i don't want them to take anything back to their house and infect their family. >> reporter: the story in arizona remains one of the governor, who wants to keep things open, versus local ele elected officials wanting to keep more things closed. last week, the governor capped indoor dining capacity at 50%, which he said was enough to curb the pandemic. local officials said they want more. evan mcmorris santoro, cnn, the grand canyon. when we come back here on "cnn newsroom," covid-19 cases in the u.s. soaring. other countries have managed to stop the spread, though. just ahead, a shocking comparison, the u.s. versus other places around the world.

welcome back. covid-19 continues to spiral out of control in the u.s., as we have been reporting, but around the world, many other countries have successfully managed this virus, or avoided it altogether. cnn's max foster has a look at how they got it right. >> they need help. because this horrible virus has hit 188 countries. >> reporter: president trump is fond of reminding us that plenty of others have struggled with covid-19. but here's the reality. for every 100,000 americans, at least 40 are dead. and the number of new cases is soaring. meanwhile, many parts of the world have either recovered or avoided the brunt of the pandemic altogether. no two strategies were the same, but public health experts tell us that around the world, there was some commonality to the places that got it right. they took the virus seriously and they acted quickly. >> when we shut down as a

nation, in reality, only about 50% of the nation shut down with regard to other things that were allowed. and many of the european countries, 90%, 95% of all activities were shut down. >> reporter: one strategy? quick and total lockdown. there's a lot we don't know about when covid-19 first surfac surfaced. the chinese government suppressed the earliest report of the virus, silencing whistleblowers, like this doctor, who would eventually succumb to the disease. but when the scale came clear, china led the way with the lockdown strategy. they ordered 11 million residents to stay home. then, more and more. 62 million by early february. there was a high toll at the epicenter, but the official nationwide death rate per 100,000 is less than one. its curve of new cases, way

down. new zealand was one of the first democracies to shut down. just two weeks after their first case was discovered at the end of february, prime minister jacinda ardern announced mandatory quarantine for anyone entering the country. that was followed by a ban on almost all noncitizens entering at all. and after that, total lockdown. the government reports that just over 20 people total have died. less than one per 100,000. its curve, down. italy was the first european country to be hit hard by the coronavirus and proof that covid-19 wouldn't stay in east asia. infections and deaths spiraled. cemeteries filled. and italy's hospitals, especially in the hard-hit lombardi region, were overwhelmed and overrun. more than 100 doctors died in less than two months of the initial outbreak there. but the government knew when to change tack. eventually, locking down the

entire country. the reported death toll in italy was high. 58 per 100,000, higher than the u.s., but is not climbing much anymore. the covid curve is now down. denmark also adopted the early lockdown. the second european country after italy and before it had a single confirmed death. its strategy stood in stark contrast to sweden, which refused to lock down to pursue herd immunity. masks have never been widely adopted in denmark. mass testing is only just taking off. but extreme social distancing allowed danes to become one of the first european countries to reopen. it has reported 10 deaths per 100,000. their curve, way down. >> when you do testing to that extent, you're going to find more people, you're going to find more cases. so, i said to my people, slow the testing down, please. >> reporter: another common technique? mass testing for the virus and tracing its spread.

vietnam had the potential to be a covid-19 hot spot, but they knew a lot about fighting disease. they also had an aggressive and innovative communication strategy. the government says, not a single person has died from covid-19 there. their curve, down. south korea also made its own test. just weeks after chinese scientists published the virus' rna sequence. they hadn't even had a single confirmed case at the time, just the genetic code. they quickly ramped up testing, setting up drive-through testing way before it would become commonplace around the world. south korea has a reported total confirmed death rate of 1 per 100,000 and their curve is down. iceland, i saw first-hand last month. it is home to one of the leading genetics labs in the world. they use that scientific know-how to trace the contacts of anyone who had covid-19. i met this woman who was told to quarantine after being in

contact with a waiter who had covid-19. days later, quarantined at home, she also got sick. the government reports 3 per 100,000 have died. iceland's curve is down. >> i just don't want to wear one myself. it's a recommendation. >> reporter: it took months for president trump to say he was all for masks. but for many places around the world, they simply weren't controversial. while the west endlessly debated face coverings, east asia drew on years of standard practice. japan long declined to lock down, but masks already popular became near universal. official death rate, 1. the covid kefsh curve is now do. america's northern neighbor has had its struggles with coronavirus, especially in elderly care homes. but the canadian government was able to keep its response free of political bickering. masks aren't controversial in canada. >> just respectable to other

people. >> reporter: canada has a reported 24 deaths per 100,000. its curve, down. turkey may not have had the mask culture of east asia, but face coverings became mandatory in public places way back in april. just 6 people per 100,000 are reported to have died there and their curve is down. american doctors know this as well as their counterparts abroad. covid-19 is new and it requires innovation. here at the university of oxford, for example, scientists have discovered the power of the steroid dexamethasone, at least according to preliminary results. germany helped avoid the wos of the up 2keepidemic by increasin icu capacity. they have so many extra beds that patients were flown in from strapped hospitals in frantz and italy. like the u.s., germany is a federal system, but chancellor angela merkel avoided the
