>> thank you. good to be here. good to be here. >> roots, our journeys home. the two-hour special premieres tuesday, 9:00 p.m. eastern. right here on cnn. make sure you tune in. make sure you stay tuned for the breaking news coverage of the latest in the ebola outbreak continues right now with cnn's anderson cooper. he is live in dallas. anderson. >> as don said, we are live. don, thank you very much. good evening. don said we are live in dallas tonight with fast moving developments in the ebola crisis. a short time ago. the latest nurse diagnosed arrived in atlanta for treatment at emory hospital. able to walk with assistance. breaking news tonight. we are learning that at least part of the reason sunny was moved. concern that health care worker at this hospital may walk out. more on that in a moment. 29-year-old amber vincent tested positive as you know after caring for thomas eric duncan who died last week here at texas presbyterian hospital. more breaking news as well. a top hospital official is now apologizing for the fact that

duncan was sent home with a prescription for antibiotics. and was told to take tylenol. in a written statement delivered at a hearing on capitol hill, the chief clinical officer and senior executive vice president for texas health resources writes, i quote, unfortunately, in our initial treatment of mr. duncan, despite our best intentions and highly skilled medical team, we made mistakes. we did not correctly diagnose his symptoms of those of ebola. we are deeply sorry. tonight a lot of concern. vincent took a commercial flight from cliff to dallas just two days ago. concern that she may have exposed hundred of people to ebola. she had elevated temperature at the time she boarded the flight. ahead of the cdc, says that never should have happened. never should have gotten on the flight. we have learned tonight. dr. gupta learned that vincent actually called the cdc before she got on the flight. and no one said, don't fly. not only that, there have been changes to the cdc guidelines of what constitutes a fever. so there is a lot to get to in

this hour. sanjay joins me live. explain what happened here. she called some one at the cdc to report her temperature. but she was still able to get on the flight. they said, okay. >> well that's what it sounds like, andersen. that is very surprising. obviously given all that we have know about ebola. and some of the concerns about flights coming out of west africa for example. here is the scenario. flew from dallas to cleveland on october 10th. october 13th. she is flying back. mind you after she has taken care of mr. duncan. by this point, they, everyone knew had, had, ebola. she is taking her temperature. that's what she is told to do. self-monitor. the morning of the 13th. she takes her temperature. 99.5. she calls the centers for disease control. says she is in cleveland. going to get on a flight. temperature is 99.5. she is not told to, not, take

the flight. there is no guidance given to her. so that's why she got on the flight. flew back to dallas. very different from what we heard from dr. frieden. she fell into the category of, of controlled movement. meaning that, that, having been somebody who took care of a patient with ebola should not have been on commercial flight. going to travel at all. should have been on a charter flight or by car. but she should never have been able to get on a commercial flight in the first place. we know she did despite reporting an elevation in temperature, andersen. >> good for her. for calling the cdc. i mean, as you pointed out earlier when we talked about this. had she been in west africa. gone to the airport. they wouldn't have let her on the flight. that's what i find so surprising. frankly, startling.

my colleague. elizabeth cohen returned from line beer yeah. they take your temperature first of all. would have been found to have an elevated temperature. give you've a questionnaire. one of the primary questions you have been asking. have you been around any body with ebola. she clearly had. if she had answered yes. that would have been flagged. likely would not have taken the flight. would have gotten more questions. would not have been able to board a commercial flight. that's west africa. here in the united states, despite the fact she fit the criteria she was able to get on a commercial flight. temperature was 99.5. she had contact. caring for a sick patient with ebola. >> why is this significant about the cdc, changing the guidelines on what constitutes a fever with, with ebola. why is that important for people to understand. >> well, you know. we place aid lot of faith in the fact that what is kidded symptomatic from ebola. fever is one of the first signs.

and it is one of the things that they use ford screening tests. as a sort of a precursor. this is going to be one of the first symptoms of ebola. you can catch it early. 101.5 has been the number. look at the cdc guidelines. recently, 101.5. now they lowered it to 100.4. that means that, people who have a lower temperature could still be at risk of getting ebola. you may have felt, you know, pretty comfortable saying, lack my fever is not 101.5. my chances are pretty low. now they're saying if it is 100.4. you are still potentially going to be some one at risk. what drove this, anderson. i find this fascinating is the first nurse, nina, when she got sick, and had the symptoms of ebola. her temperature was lower than that. they got the doctors and everyone thinking. was she developed symptoms of ebola without a, without a true fever as we have defined it. maybe we should revise our

guidelines. >> so, what to me, stand out about this. correct me if i am wrong. all along. based on what the cdc said. until you have the fever of 101.5. it seems what the cdc is saying. that wasn't true. now, we think it's -- 100.4 that you'll, that you are actually. and that you are able to tran mitt it to others. is that correct. are they essentially kind of, correcting themselves after, after kind offing sure people that they knew the parameters on this thing. >> they're clearly revising their guidelines. because, now they have evidence of this, this patient. the nurse, first nurse. who clearly had, all of the, many of the other symptoms of ebola. the nausea, vomiting, perhaps. things very concerning. but did not have the fever of 101.5.

just placing so much faith in the, if some one doesn't have a 101.5 temperature. we don't worry about that. seems to be, poor thinking. now we are saying. even, lower than that. you could still develop the symptoms of ebola. it is fair to say if you don't have other symptoms. if you are not vomiting, don't have some of the symptoms in your, that are associated with bodily fluids. you will be low risk. spreading the virus. what is considered symptom attic. big question. that seems to be changing. steams to be getting, to, encompass a larger group of people. than we previously thought. >> i wondered, sanjay. bring in jeremy bole, of mount sinai health system. thank you for being with us. you say that nobody should ever work with ebola patients unless they're confident that they have been trained to use the protective equipment and that's within of the thing that nurses at the hospital here have apparently been protesting. they didn't have enough training. or even proper protocols to

follow. i talked to dr. mccormack who said he talked to nurses at another hospital in, in texas, who said that, basing lie they were told to watch videos on youtube. does that worry you? >> of it does. at the end of the day. every nurse. everybody who comes in contact with a patient at risk for ebola or has ebola has to be fully trained. and feel very con fi didn't not only that they know how to use the equipment. they're using it with a buddy watching and making sure they're putting it on the right way and removing it. donning and doffing correctly. because when patients with ebola are most infectious, sickest, having vomiting, diarrhea and the like, that, those stepdz become incredibly important in terms of preventing transmission. i think that is fine for general

education. when it comes down to treating a patient, there need to be serious attention and drilling of the staff. until they're compa tent and feel con fi didn't they know hows to use the equipment. >> i know, mount sinai. i tacked to one doctor on the program the other day. who said early in. there was a scare. early on when the cdc sent out, kind of a head-up bulletin to mount sinai and hospitals saying, you know be on the lookout. you started drilling. kind of preparing for this. that seems like it did not happen at this facility. >> how it seems. we don't have the facts on the ground in dallas. mount sinai health system. not something you can fix overnight. we are not satisfied with the work we have done yet. people say safety is a dynamic

nonevent. if the takes an enormous amount of energy and effort to create an environment where nobody gets hurt. >> san jay, i have been surprised by the lack of transparency from the hospital in dallas. not to bash or point fingers at them. i do think transparency is important to inform the public and other hospitals about what went right more importantly what went wrong. what didn't work. this hospital has not been transparent at all. we have heard nothing directly from the hospital really about, the problem that they faced. about what went wrong. what they didn't do right. now we have a health official tomorrow, apoll jogizing before congress. with no level of detail. what went wrong. >> the details are so important. sa anderson for the exact reasons.

look, incredibly uncomfortable for the officials in this hospital to, to, to, apologize. to admit their mistakes in the situation. as you point out. correctly. it is really not, that's not the most important point anymore. the most important point is that this is a good hospital. a great reputation. yet the mistakes were made. the same sorts of mistakes could be made at other hospitals. the other hospitals need to hear from them. what happened here in dallas because -- there are going to be other patients that arrive in the united states. they can be cared for. ebola has been contained. it has around the world. western, central africa for decade. it can be done here as well. what went wrong? my guess not going to be stuff that is particularly complicated or difficult to fix. but they've don't know what the problem is, then how are you going to fix it? they need to be transparent. i hope that we hear some of that

tomorrow during the hearings. >> doctor, do you guys, as a hospital. do you have some sort of, even private communications with other hospitals like, does this hospital contact you and say, you know what, here is what we did wrong? i am not saying that they need to tell the media about it. but it would give me a level of confidence. of at least they were communicating with other hospitals. does it work like that at all? my sense is it doesdoesn't? we haven't had a communication with the hospital per se. we have been in close contact. with emory, with other hospitals in new york. with the department of health. leadership here in new york. and what they're trying to do is share best practice. what can we learn from our colleagues and peers. so that we don't, we don't repeat mistakes. >> that are avoidable. >> yeah, doctor, more with you and sanjay. stick around. more in this hour. including answers to viewer question as but ebola. flooded with questions. fears, concerns about the

disease that spread beyond dallas, obviously. the latest nurse to be infected traveled via commercial airline before she was diagnosed. amber vincent is her name. went on a trip to ohio. returned to dallas. two days ago. now that trip has affected kent state university. where her parents and another ro relative work. i am joined live with the latest houf how did vincent spend her week end. a statement from kent. she did not come on campus. no ris tubik to anybody on camp. >> hi, anderson. we don't know much about how she spent her weekend here. flew here friday. went back to dallas monday. we don't know with whom she met. other than being at home. did she go some place else? meet with other friend? we don't have the details now. as you said kent state university did make the point that she did not visit the campus here. she graduated here, got her nursing degree, bachelor of science big from here as

recently as 2008. >> her parent and another relative did visit the campus as i understand. but, i mean there is no way they could have, even if they, they had become infected by her, they wouldn't have, gotten, dumb down with down -- come down with it so quickly to pass it to others. correct? >> very unlikely. her parents and one relative do work here on the campus. kent state said that they're not faculty member. they have other jobs here that they won't characterize or define in any way. they said they came here to work here, they normally do, monday, tuesday. they think even on wednesday, today. once they found out, from the nurse, from their daughter, from vincent, that she had become ill. the parents contacted kent state university. told them about it. they were told to just go home and stay at home for the next 21 days. as a precaution. it's not clear whether they're

there, in a mandatory basis or, it is voluntary. but, they, they haven't been back to work here. and, there is no major concern here on campus. susan. good information. thank you. started to become a refrain in the story. concerns of ebola spreading throughout the neighborhood. where the patients live. it happened at thomas duncan's apartment. and the nurse's neighborhood. now the dallas area where amber vincent calls home. gary tuchman was there. >> reporter: amber vincent's home in the village apartment complex. a few minutes from the hospital where she works as a nurse. sadly there is a routine we are getting used to when a case of ebola is diagnosed in dallas. the police arrive. their crime tape goes up. hazmat workers arrive. trucks pull in. news choppers fly overhead. all of the cameras focus on the victim's home. the ritual also includes authorities texting, calling and knocking on the doors of neighbors. >> they told me there was an

ebola patient in my apartment complex. >> we were -- woken up by 6:15 in the morning with a notification that a third ebola case had been verified. >> i have some friend that are, that i thought were a little overly paranoid. now it is right across the street from me it is scary. >> the worst thing you can do is panic. >> i agree? are you anxious? >> little anxious. i want to know where is it sghoeg what going to lead to. >> i had a bad stomach virus. four days ago. it went away. if i would be sick right now i would be scared. >> and also a neighbor. what she tells us about a part time skjob she has also tells u about the times we are living in. >> this morning i was babysitting a woman with a 3-year-old, newborn, had multiple baby silters some of them have nurse jobs. told the ones who are nurses she

didn't want their services any more. understandable. from my view i was like wow that is a pretty major decision to cancel someone's job. >> you are saying she canceled the nurses because there are two nurses that have come down with ebola, afraid to have nurses? >> exactly. >> this man says he and his wife have vowed not to change their lifestyle. but to stay aware. >> we keep informed. what is going on. and now that it is here, more so. >> that's the way so many people feel in this neighborhood. and this city. gary tuchman joins me. do you fiend people are frustrated? expressing frustration, lack of transparency from the hospital. do you find people expressing that to you as well? >> all over the city, people are bewildered, the lack of communication from the hospital. this hospital is a very respected institution in this community. i have a buddy, i went to high school with in new jersey. moved to dallas. he had retina surgery.

he had topnotch care. we are seeing now in the community, a lot of people saying -- maybe there is a person or persons in this hospital, more concerned with, covering their behind than giving out relevant information. >> circling the wagons. protect themselves. hopefully change. in a couple days. gaesh appreciate the reporting. quick reminder, always set your dvr, watch 360 when you like. just ahead in this hour. how medical groups, treating ebola patients in west africa how they're managing to keep most if not all workers safe. this is really interesting. they don't have the same high-tech equipment as a lot of the hospitals do. they're working very tough conditions. but what they say they need to keep battling the outbreak. going to interest you. plus the litany of missteps here in dallas. that began with misdiagnosing with thomas duncan. seemed to keep getting worse. more on allegations from nurses that cared about him from the nurses union. we'll beef right back.

protecting its employees. and the public at large. the statement read in part. texas health dallas is offering a room to any of our impacted employees who would look to stay here to avoid the remote possibility of any potential exposure to family, friend and the broader public. we are doing this for employees' peace of mind and comfort. not a medical recommendation. we will make available employees who treated mr. duncan, a room in a separate part of the hospital throughout their monitoring period. that is after a second nurse, amber vint ecent contracted ebo. she arrived in atlanta for treatment. vincent and her co-worker the first u.s. health care workers infected with ebola inside american hospital. part of a much larger story to the day the world health organization said that nearly 9,000 people have been infected with ebola, mostly in guinea, liberia, sierra leon.

the numbers include 427 health care workers ill in africa, 246 have died. and groups, doctors without borders have lost workers in this epidemic. for most part they're able to keep their workers safe because of their safety protocols. sean casey ebola emergency response team director for international medical core which opened in liberia a month ago. i spoke to him earlier. sean talk to me about the protocols you use through imc and your clinics. is there, the protection health care workers, is it about the kind of gear, the protocols that are in place, the simplicity of the training, what? >> it is important to have the right gear. we use the same standard, doctors without borders. tie chem suits. separate hoods. three pairs of gloves.

most important thing is how you take it off really. that is up to 20 steps that have to be followed in sequence, supervised. we have safety inspectors who watch our staff doff their personal protective equipment. they call out every motion. >> those protocols were not in place clearly early on at this hospital here in dallas. the protective gear they were using it not as advanced as protective gear you were using. your clinic has been open for a month. none of your health care workers has been infected. it isn't the most sophisticated medical facilities. people assume a hospital in the united states, treating ebola patient, extremely sophisticated facility, but that's not, necessarily, what's going to make the difference. >> no. >> our yoebola treatment unit i in the forest down a dirt road next to a leper colony. over 100 patients in the last month since we opened.

staffers say, not really sophistication of the equipment that we have. following simple protocol. how the equipment is put on. how it is taken off. and how we move within the ebola treatment unit to not contaminate ourselves and to keep our hands clean. >> so does it surprise you've the problems medical workers are having in the united states at least at this hospital? >> well, it's not entirely surprising because i think our staff have had more training than some staff in -- would have in the united states. because we are trained to dupe what we are doing. all that we do here. >> there has been talk here in the united states. of travel bans, of stopping commercial flights. do you have a problem keeping staff, getting staff in and out. because that's one of the arguments against some sort of, an all-out ban. it would make it more difficult for aid workers to come back and forth? >> yeah. the international air connections are critical for our staff. our volunteers and supplies to get here.

there is a physical issue and a psychologicaler to. the physical issue is that we need to move bodies and supplies to get here. and if we don't have those flight connections that becomes much more complicated. psychological barriers, we need people to feel confident coming here. if they're not sure they're going to come home. it's harder to recruit and retain. >> i heard aid workers say there need to be a greater footprint on the ground. more personnel from more organizations, from more countries. from governments involved, money that is being donated. there just need to be more on the ground. in these countries. is that what you are seeing as well? >> yeah. we need more of everything. actually. you have been in the philippines, haiti after disasters. a rush of organizations and aid workers. within days. here it has been months of trickle. we we just don't have enough hand on deck. there aren't enough organizations. some of the resources are starting to come in. this is an enormous task that covers multiple countries.

it requires technical expertise. infrastructure. all kind of thing that have to happen simultaneously. and, we are not moving fast enough. appreciate all you and your organization are doing. thank you so much. >> thank you, anderson. >> just want to underline something sean said at the end. they're not moving fast enough. just not enough personnel on the ground. there is not enough government donating money, governments donating, sending medical personnel over there, groups, sending medical personnel over there. it, this thing is not under control. and until it is under control in, in liberia, in sierra leon, in guinea it will continue to be a problem everywhere else in the world. chief medical correspondent, sanjay gupta, joins me, and an infectious disease researcher at harvard university joins me. sanjay, sean was saying there, his treatment center. as i said, in a forest down a dirt road. next to a, a, you know treatment

center for people who have leperocy. to keep the staff safe. craw don you don't need a high tech sophisticated hospital. this high tech hospital in dallas couldn't handle it the way they should have. >> there was a great interview. and it made some important points. i hope everyone hear the point. the idea of keeping the health care workers safe is something that can be done. is being done. when it is booing doeing done i tough spots around the word i you are asking yourself, watching this. if they can do it in western central africa without hardly any resources. why couldn't they do it in dallas. and itch yf you are asking the question you, are asking the right question. this isn't challenging. in terms of what need to be done.

it spreads through bodily fluids. if they get on your skin. you have breaks in your skin. a source of infection. so cover your skin. hate to sound simplistic. that sounds basic. and then, you, we know the protocols at the, that the ebola, protocols from the cdc there in dallas did not always allow the skin to be covered. sean made some really good points. and genetic research. trace the origins of this strain of ebola. and the zaire strain. back to a single infection last december. what have you learned about it. how concerned are you about the ability of this virus, to, to, to transmit. that this is, who, the world health organization. they're warning of 10,000 new cases a week. currently 1,000 case is a week. 10,000 cases a week by this december. if things continue down this

path. >> absolutely. anderson. that's a major concern. a concern for a long time. what's going on in liberia. the important thing to note. this is something that we can contain. this is a virus. actually, even though a lot of people have been talking about the transmission. the transmission is trackable. we know who contacted who. these are, airdroplets that may be, people with close connection with each other. we can with good diagnostic, contact tracing pursue this in other countries. then focus our attention on liberia, sierra lee yoeone, and guinea. we have the tools to do it. >> when did you trace it. this outbreak, do you know where it started and how the? >> well right now we have limited, we have limited samples we are able to sequence. sequencing technology is available that as we have samples we can analyze them. we can see what is going on.

what we see, a few strains, sequenced in guinea, a number in sierra leone, likely a child in guinea. we are seeing these, individual transmissions. we can actually trace the transmissions through the sequence of the virus. we can see who is likely to have transmitted to who. >> fast cinating work. >> there is word the cdc might add ebola patients to, not only patients, people who have had connection with ebola patients to a no fly list. is that a good idea? does that make sense? >> i think it probably does make sense. i think dr. frieden eluded to that in his comments. he said patients who are being monitored, either self-monitoring, taking their own temperature thousands, or being actively monitored. some one comes in and takes their temperatures.

record that. he said they shouldn't be flying. shouldn't beep getting on xher sthal flights. get on charter flights. they could get in their cars. drive around. but they should not be on commercial flights. so, the way he describes it, andersen. it sound like that was already, their recommendation. so, enforcing it. giving it teeth through a no fly list. it does seem to make some sense. >> doctor, always a fear amongst some people that a virus can mutate. and some how in this case become airborne. is that a real possibility with ebola? >> so there has been a lot of discussion about this idea of airborne or not airborne. ebola can be transmitted in particles, droplets. that's why health care workers are at great risk. we have to focus on individuals with singular contacts. airborne is a different thing. usually with respiratory viruses, usually with virus that can be dried into drop lets and go, sort of in the air.

that's obviously a frightening idea. something where you wouldn't know who infected you. that is likely many mutational steps away for this virus. so that is not the main thing we should be concerned about. nonetheless, we know the virus does change over time. and it is having a lot of human to human transmissions. most important thing we should do is regardless stop the virus. so we need to set up diagnostic capacity across the countries, all countries to make sure we can detect it thevenlt . then focus attention on countries that need our help. >> doctor. appreciate you being on. sanjay stay with us as well. the crucial missteps in the dallas hospital. how we got to this point? i want to get to sanjay's take on all that. and answer questions from you, our viewer, we'll be right back. jobs all over america. engineering and innovation jobs. advanced safety systems & technology. shipping and manufacturing. across the united states, bp supports more than a quarter million jobs.

>> welcome back. hearing from a lot of you asking some important questions about ebola. we wanted to take team to night to answer some of them with dr. sanjay gupta, emory, university.

and the chief medical officer of the mount sinai health system in new york city. sanjay, one of our viewers, madeline posted on facebook, what happens when a sick person goes to emergency and diagnosed with ebola, entering the elevator, talking to nurses on check-in, all the people are exposed. how is that taken carry of for walk-ins, the protocol? >> well it is a very good question. and it's not going to be a, completely precise answer. here's how things should work. if there is a suspicion, so based on travel history, symptoms, based on the things, sus pe suspicion some one has ebola. the first step, some one should be put in isolation. you might away want to mitigate, minimize, the number of people the person comes in contact with. can't make that zer roiero. some one is going to evaluate, take a history all of that. reduce it as much as possible.

as you know doesn't sound look that is what happened in the case of mr. duncan the after the suspicion was raise add but him. he was in another room with some seven patients. shouldn't have happened. and took the patient in. and social number. would that person then have to just monitor themselves for the next 21 days. and considered potentially have come in contact with the patient. may not have been providing direct care, close enough to potentially be a contact. they would have to usually self monitor. taking their own temperature for 21 days. >> sanjay, we talked about this a little bit last night. appare tape around their necks early on. would that work as a preventative measure. >> i never heard of that either. i have some of the tape. wanted to show you. this is what they're talking

about. the concern was the nurses said their necks were not covered. that was a potential portal of entry. i am'goi they were told to put the tape around their neck. wrap it around. four, five pieces. wrap it around. it's permeable. wouldn't do the job if they did do this to. be clear. this wasn't a hospital policy. what it sound like, somebody who was frustrated. don't have a good answer in terms of how the nurses should protect their neck. said maybe just wrapping tape around it would be, an option. turns out that was a bad option. don't think that was hospital policy by any means. >> doctor, dee on facebook was wondering why are being being monitored not under quarantine? >> folks who are being monitored who don't have a fever and -- don't have any symptoms, they're not infectious. they're not at risk to anybody. the monitoring is, to catch -- somebody early on in the

process. so they can be put into a qua quarantine situation if infectious. if they have been exposed no fever and symptoms, they're not at risk. >> are you confident that we know enough about yb ebola to determine, talking temperature, 101.5, now 100.4. seems like that is shifting a little? >> you know i think what the cdc is trying to do is cast the broadest possible net. so nobody who is infectious slips through. a normal healthy immune system as vast majority of people do. they have no fever. no symptoms. that is a reasonable standard to say they're not infectious. whether they become infectious. at 100.4, 101.5 is debatable. the smart move. when we don't know to move that

back to 100, 100.4. really, rain evidence of fever at all. let's just be safe. and keep other people safe. >> right. >> doctor. appreciate you sticking around. answering questions. thak very much. sanjay, as well as always. my conversation with dr. kent brantly. remarkable man. ebola survivor. donating his own plaza. to other ebola patients here in the united states. we'll hear from him ahead. ♪searching with devotion ♪for a snack that isn't lame

nurse. and the doctor advocates passionately for patients in west africa. i spk to hoke to him. how are you feeling? >> i feel good. >> become to full strength? >> i don't know when i will say i feel back to normal. but my strength, my stamina energy are improving a lot. i feel a lot better than two weeks ago. >> when you heard about this latest case in the united states, i am wondering what want through your mind? >> my heart just sank. you know, health care workers go into this profession to serve people, to relieve suffering, to cure disease. to come alongside people in the worst times of their lives. here we have a second health scare worker in dallas. doing just that for a patient suffering greatly.

now she is sick. and it just, made my heart sink. and, praying all over again for the, for the staff. staff of the hospital there. >> obviously a lot of concern in the united states. about the spread of the disease here. and not only, what's happening in west africa. the spread of disease here. do you think the concern about ebola spreading to the united states is justified. do you worry about ebola spreading to the u.s.? >> a lot of irrational fear about ebola spreading in the united states. we think about what weave have seen so far. we had one man who came from liberia, contracted the disease there. came to america, got sick here. and now who else has the gotten sequester from h sick from him? two health care workers taking intimate care of him, cleaning up his bodily sfluids, the two who got sick. not 48 people being tracked bay the cdc. the 48 who had can taontact wit

in the community. none of them got sec. those taking close care of him in a hospital setting. >> do you know how you got it, a moment you look back on it and say that was it, that was the moment? >> i'm convinced that i did not get ebola in the isolation unit. >> really. our process there was safe. every time i went into the unit full of ebola patient. i was fully suited up. in the suit. >> covered? >> every centimeter. every inch. >> iaw >> there is a sentiment, let's stop flights. shut down west africa. until this is dealt with in west africa, until the jut break is controlled, and stopped in west africa, it is going to continue to come to the united states. going to come to western europe. going to continue to -- at least the possibility of spreading around the world? >> that's absolutely correct.

until the epidemic is stopped in west have ri ka west africa. there have been suspected confirmed cases in the united states, spain, brazil had a suspected case. three continents outside of africa that have been affected by this epidemic the this outbreak. and the answer is not simply close the borders and, and let them deal with it themselves. we have got to be proactive. we have to go, put an end to this epidemic. or it is going to keep coming back. to, to, cause problems and suffering in the global community. >> you have done something which is really struck a lot of people. you have repeat lead donated your own blood, your own plasma in order to, to help those who have been affected. you have -- you have, is the four times now that you have done this? >> three or four. >> three or four.

>> what's that process like? >> so i have donated my plasma which is not actually whole blood. the blood is made up of red blood cells and plasma. so they can take the blood out of my arm, and put it in a special machine that separates the red blood cells from the plasma and give me red blood cells back. they take the plasma. plasma is the part of the blood that contains the antibodies that, that will fight ebola. that's the part of my blood they're taking and giving, an x experimental drug to the patients. it is fortunate that the three patients i have been able to donate too. they and i share the same blood type. and that's why i have had the unique opportunity to help in that way. >> would you donate plasma again if you were the same blood type? >> i pray there is no more need for plasma donations in this

country. i will keep doing it as much as is needed as much as i can. if it will help, if it will potentially help save some body's life. >> up next, america's top general weighs in on the ebola crisis in the united states. is he as concerned as many americans, and satisfied with how federal health officials are handling the crisis. that's ahead.

been a fast-moving day for many here in dallas. a second nurse, treated thomas eric duncan is infected with ebola. the fact she flew on a commercial air lean with an elevated temperature has people worried. president obama promised a more aggressive approach to containing ebola in the united states. and we sat down with the chairman of the joint chiefs of staff for an exclusive interview. she asked him about the crisis and the response so far. >> are you, general dempsey, worried about ebola here in the u.s.? >> high have been worried about ebola globely 90 days. some on my staff were worried, a few weeks or months before that. >> why? >> i am worried about it. because we know so little about it. you will hear different people describe whether it could become airborne. if you bring two -- you know, two doctors who happen to have that specialty into a room. one will say no way it will

become airborne. but it could mutate so it would be harder to discover. it actually disguises itself in the body which makes itself dangerous and incubation period of 21 days. a doctor will say if it continues to mutate at the rate it is mutating and go from 20,000 infected to 100,000, the population might allow it the opportunity to mutate and become airborne. then it will be a extraordinarily serious problem. i don't know who is right. i don't want to take that chance. i am taking it seriously. >> with this ebola situation and all the major gaps in the system that we have seen, the cdc director said the agency should have taken control of that dallas hospital. what does that tell you about the u.s.'s capability to respond to a bioterror attack? >> we have a contingency plan for managing pandemics. that is things that would begin to exceed capability of a particular community or state even to deal with it. and we update it periodically.

one of the cases we are dusting it off. closely in contact with all of, national institute of health, world health organization, centers for disease control, u.s. agency for international development for the stuff going on overseas. >> so what do you say to all americans looking at this ebola situation and are in absolute panic? >> ebola is a -- to use a sports metaphor, this need to be an away game. that's why the united states military is involved. we want to keep this, we want to help international health organizations service organizations, nongovernmental organizations, we want to help them keep this in isolation inside of the three countries. but, i have studied this thing. there is risk that it, that the, that the rate of reproduction, the ability of one patient to affect, two, four, eight, it becomes exponential. we have really got to be aggressive about the isolation

and treatment matters that we are take inside the homeland. we are in support of those. but i can promise you that the united states military will do its part with civil authorities to cokeep this thing from comin to our homeland. that does it for us. we'll be here tomorrow. and "somebody's got to do it" starts now. >> i was moving that old steeple. anyway, i'm heading back to maryland. that's a whooping crane. they're not dirty at all. but to save them, you have to hide under a white sheet. didn't say it wasn't weird, somebody has got to do it. new show, new mission, somebody has got to do it. so i get e-mail all the time from people who say i must absolutely watch this.
