dr. besser joining us from washington. good morning, dr. besser. this case, as we mentioned, has to be confirmed. if it is how big of a net do you cast regarding those affected and who will health officials be looking at? >> just like with mr. duncan where they looked at casual contacts and close contacts, you want anyone who's had contact with this individual while they were sick. so you cast a very wide net and then you narrow that down as you really explore what kind of contact they had. >> now, this would be the first transmitted case of ebola ever here in the u.s., so what are the next steps of containment? >> well, this is very disturbing if this turns out to be true and they're going to need to look and see what happened in the hospital to allow this to occur. if it were someone who met him when he first came in the hospital, that's one thing, but if he was part of the care team of the patient while he was in the hospital, it really throws in the question the cdc recommendations that any hospital can take care of a patient with ebola. they j

dr. richard besser. with us from liberia tonight. dr. besser will have much more first thing in the morning on "good morning america." >>> in the meantime, we turn to the other breaking story we're following tonight. stunning new revelations about that white house intruder. sprinting across the white house lawn, armed with a knife, getting through the front door. and we now know getting much further than we all knew. only tackled once he reached the east room. well, tonight, we have learned he was brought down by an offduty agent who wasn't even on the clock. tonight, the new details and the new questions here. did the secret service mislead the president? how much did the president know? abc's senior justice correspondent pierre thomas now. >> reporter: the criticism about how this man defeated the secret service security machine was blistering. >> this was a stunning, outrageous, disgraceful breach. >> reporter: bipartisan. >> don't let somebody get close to the president. don't let them get in the white house. ever. >> reporter: and th

dr. besser is standing by, answering your questions again. but first, abc's cecilia vega live in dallas and leading us off. >> reporter: david, good evening to you. that ebola patient fighting for his life right here behind me. i spoke with his wife, who is in quarantine right now. she told me today, i just want my husband to be well. inside this apartment in dallas, a family in quarantine. relatives of the first person ever diagnosed with ebola in the united states ordered by law not to leave and we know they've tried. a police officer now posted outside. food and supplies delivered. even the walkways hosed down. >> nobody's supposed to go inside the apartment. they are in their apartment. they cannot come out. >> reporter: disease detectives now in a race to answer one question. how many people could one person have infected? their investigate starts here. with thomas eric duncan in isolation at this dallas hospital, he is patient zero. the cdc now tracking 100 people he may have come into contact with. first, the doctors and nurmss who tre

dr. richard besser is here. dr. besser, the cdc has been saying all along that there are protocols in place to prevent exactly this. are hospitals ready for this epidemic? >> reporter: i don't really think that are. it's not so easy to do this correctly. take a look and see what was involved when i went into the ebola ward in liberia. several people suited me up. they made sure that every spot of skin was covered. and then coming out, the critical point. they made sure that they sprayed me down as i took off every layer of clothing. you need to be able to train, to practice and be supervised. it's not easy. >> you've seen it there firsthand. what should hospitals, if anything, be doing differently here at home? >> reporter: well, every hospital has to be ready to receive someone who may have ebola. so, they have to ask about travel. if they're suspicious, they need to isolate and test. but at that point, if they have ebola, they need to think about transferring to one of the four hospitals in america who are trained

dr. besser discovered. >> reporter: the stour story of in america starts here. i'm in a small courtyard. this is where thomas eric duncan lived. he's the man that brought ebola to texas. in the late afternoon, he walks a quarter mile to this local health clinic. she's checking in on his neighbor, 19 and pregnant. she's very sick. nurses there showing us her chart. she had weakness, poor appetite. yeah. she fainted. when duncan arrives, the situation is grim. she was not getting better. her pressure was low. she was anemic. she had malaria. they called for a car. duncan helps put her into the taxi and climbs in with her. 20 minutes later, they arrive at the ebola treatment center at jfk hospital. a place where patients wait, degs pratt to get in. no room. they strive to the elwa 2 clinic, a half hour away. no room there, either. they turn back home, returning

dr. besser here tonight. dr. besser, thank you. >>> now, to the other developing story at this hour. the stunning new images of that moment of terror, just 60 miles north of the border. video now of the alleged gunman. watch this. a car approaches. the crowd sprinting away. and here's why. the gunman, jumping out of a car, carrying a rifle. running outside parliament there, as bystanders race for cover. what we're now learning tonight about the suspect. how many times he'd been to the u.s. and we have new images of the victim. a young father and soldier who loved dogs. he saved one. abc's dan harris is in ottawa again tonight with the incredible new footage. dan? >> reporter: david, good evening. tonight from the scene of the crime, we are just outside canada's parliament building. as you mentioned, we are now getting a vivid new look at the rampage that took place here. also tonight, we're getting a sense of just how close the gunman got to this country's prime minister. this is the moment the attack on parliament begins. the new video shows the suspect leaving his car and sprinting

dr. besser today. let's bring in rich from dallas now. and dr. besser, we know that kent brantly's blood, his anti-bodies were used to help some of these patients. but he's just one man here. so, where are we on that and on that experimental drug with now another nurse getting sick? >> reporter: yeah, at this point, we don't know whether his blood is the same type as amber's. if it is, he could donate for her, as well. other drugs are under development, but the main treatment she'll be receiving is fluid replacement and nutrition. many patients get better with that alone. >> but those drugs still in treatment and not ready to be administered to these patients. and rich, we know the second nurse infected flew from cleveland back home to dallas. not knowing she was sick. but that other nurse was already in the hospital, so, the question, why wasn't there an alert to everyone who worked with nurse number one not to get on a plane? >> reporter: yeah, david, at this point, we don't know that she even received a warning to not get on that plane. that's

dr. richard besser, back from that drill. this is a big question. we saw what happened in dallas, the patient turned away the first time he went. was there anything encouraging that you saw today? >> reporter: there was. i'll remember the look in the eyes of the doctor when he said it was a wakeup call. he said they're drilling to the next patient who walks in with ebola, they're not going to miss it. >> doctors and nurmss at the ready. rich, thank you. >>> we're going to turn now to alarming images and claims of excessive force tonight in indiana, erupting during a routine traffic stop over a seat belt. all of it caught on camera by children in the backseat. abc's steve osunsami on the case tonight. >> reporter: caught on tape. a family of four -- >> are you going to open the door? >> reporter: on their way to see a dying mother stopped by police. >> oh [ bleep ]. >> reporter: the officers with the heavy tool and the stun gun and today in a statement, admit this all started with an alleged seat belt violation. >> all of my windows is up. i feel lik

dr. richard besser inside a hospital drill. so many of you asking, what's being done after that breakdown in dallas, after that patient was sent home the first time he showed up. and what about that patient tonight? let's get right to cecilia vega, she's life live in dallas again for us. cecilia? >> reporter: david, good evening to you. thomas eric duncan is receiving that experimental drug that you mentioned. his family says he is showing some signs of improvement, including now having a normal body temperature. but he is still here, in critical condition. tonight, as thomas eric duncan fights for his life, outside this dallas hospital, his mother is speaking out. >> i just want to see my son to be all right, to be healthy. >> reporter: and now, new questions about whether western hospitals are ready to handle infected patients. >> the enemy here is a virus. the enemy is ebola. >> reporter: new concerns tonight after a nurse in a spanish hospital became infected while cleaning a missionary who died from ebola. she is the first

dr. rich besser, thanks. great to have you back. let's take this now to dr. tom frieden, the director for the centers for disease control. you just heard dr. besser right there. is he correct? >> well, absolutely. the virus is moving so fast but our response is moving very fast, as well. the defense department is on the ground. they're working with 135 of the cdc staff who are there and working with usaid and others and the challenge of putting up a treatment unit isn't easy. it's not a question about construction. it's about training, supervision, supply chains and all of that is moving, but we wish it would move faster but it's moving faster than it was a week or two ago. >> i want to get back to that in a minute but let's talk about the situation in the united states now. we heard that a patient treated in nebraska for ebola, dr. rich sacra, is back in the hospital in massachusetts. what can you tell us about that? >> it's extraordinarily unlikely that it would be a recurrence of ebola. we've never seen that. but we're not going to take chances so we'll te

dr. besser with us from dallas. rich, thank you. president obama speaking shortly before we came on the air and i want to bring in jonathan karl, and jon, what did the president say we will do from this point forward? >> reporter: david, the president said he has ordered the formation of a rapid response team, essentially a medical s.w.a.t. team that would go into action immediately if there are any further cases of ebola. and after meeting with his team for more than two hours tonight, he said that he is absolutely confident that we can prevent a serious outbreak in the united states. >> all right, jon karl live at the white house. jon, thank you. and one more note on this tonight. wall street. ebola fears rat. ing the markets today. among the concerns. the dow closing down 170 points. at one point, swinging more than 600 points during trading. >>> but we do move on tonight. powerful storms in the east sweeping through the m mid-atlant mid-atlantic. this is time lapse video of the hail in washington, d.c. the capital suddenly hidde

dr. besser is standing by. but first, abc's linsey davis leading us off. >> reporter: inside this ambulance rushing to bellevue hospital today, 33-year-old craig spencer, a doctor without borders physician, suffering from fever and gastrointestinal symptoms. a suspected case of ebola, right in the heart of new york city. dr. spencer had been treating ebola patients in guinea, one of three hotzone countries. last thursday, he flew home, connecting through brussels, before arriving at new york's jfk airport. he had been monitoring his temperature, and reported his fever this morning. today, police officers in masks. neighbors anxious. a local councilman trying to calm fears. >> frankly, people in the neighborhood are scared. and some of them are panicked. in fact, i had one gentleman who shouldn't even shake my hand because he was scared. >> reporter: the health department says a team of disease detectives immediately began to actively trace all of the patient's contacts to identify anyone who may be at potential

dr. richard besser with us again tonight. rich, thank you. and he'll have much more on "gma" in the morning. >>> to the other breaking story we're following tonight. fallout now from that intruder at the white house. the man sprinting across the white house lawn, through the front door. finally tackled by a secret service agent who wasn't on the clock. tonight, the head of the secret service, out. that suspect in court. and new revelations about that other security breach we first reported on last night here. the president in that elevator. abc's senior justice correspondent pierre thomas back on the story now. >> reporter: in the end, secret service director julia pierson could not protect her own job. >> over the last several days we've seen recent and accumulating reports raising questions about the performance of the agency and the president concluded that new leadership of that agency was required. >> reporter: pierson could not survive the devastating september 19th white house security breach when an intruder with a knife jumped the fe

dr. richard besser has been in the ebola hot zone covering the story for us. he just returned to the u.s. this weekend. he spoke to rebecca jarvis about whether the precautions being taken are enough. >> i had my temperature taken three times before i got on the plane in liberia. someone looked me in the eye to see if i looked sick. i had a detailed questionnaire. that makes me more comfortable that people that are sick are not getting on the plane. if i were taking tylenol, those symptoms wouldn't show up. or if i was not honest on the questionnaire. we have to knock it out in africa so we're safer here. >> we'll have much more from dr. besser later on "good morning america." >>> a second new jersey preschooler is being monitored for enterovirus. eli waller's death is the first linked to enterovirus 68. he went to bed with pink eye and no other symptoms and never woke up. there have been confirmed and suspected cases in 46 states. >>> in pennsylvania, search teams looking for accused cop killer eric frein are focusing on a small area after a possible sighting

dr. richard besser is back here. great to have you back. >> good to be back. >> the question, is it safe for to you be here? >> yeah, i think anyone who saw the reporting out of africa is asking that question. the answer is, yes, it is safe. for a number of reasons. first, i was taking incredible precautions to not be exposed. but ebola is transferred if you're sick. any sign of fever, i wouldn't be here. i would be getting evaluated. i can't spread the disease unless i'm sick. >> let's take a look at the picture. this is a man from brussels to newark. he appeared to have symptoms of ebola. tum turns out, he didn't have thes did. is it going to be a concern going forward? >> here is the thing. ebola has a long incubation period. it's possible to develop a fever in the air. you only get the infection if you are exposed to someone's body fluids. and that happens later, usually the second or third danchts you have now traveled the exact ruth. do you believe we can stop the disease at the border? >> the amount of screeni

dr. besser, let's start with you. what should happen next with the lab technician that's on board of that cruise ship? is the caution warranted? >> i think that what they should do is leave that person alone. and here's the reason. she never had contact with eric duncan. she never had physical contact with any of his body fluids. i'm not sure why they were watching her. and i'm not sure why they tested her blood because for ebola your blood test is only positive if you have symptoms. she's 21 days out. let her go, let her alone. she's not a risk. >> 21 days is that incubation period and speaking of, as of today, family members of thomas eric duncan, the ebola patient who died, are no longer under quarantine. what does that tell us about this disease? >> this is good news and hopefully for a lot of people it's reassuring. these are the people that had the closest contact. some of these people were living with him in the house. his fiancee who was in the house for four days after he was in the hospital, negative. this s

dr. richard besser who is in williamstown, massachusetts. good morning, dr. besser.irst and foremost, these mandatory quarantines for medical workers returning from the ebola hot zone now in several states. why don't you support these measures? >> you know, when i hear this story of how she was treated, it's actually chilling. what's going to make it safer for us here in america is to get as many doctors, nurses, health care workers to go to west africa to knock it out there, and anything like this, it creates a disincentive. you know, when someone is treated this poorly when they return, why would anyone go over there to help? >> deter us from the really important work that needs to be done on the ground right now. so, let's talk about the public fear we're seeing over ebola. you say elected officials are creating an unnecessary sense of panic with these quarantines. >> i think they are. what people need to realize is that no one can spread this disease until they have symptoms, until they're losing body fluid, so having health care workers and others monitor themse

dr. richard besser who has made two trips to liberia covering the ebola outbreak for us and dr. anthony fauci from the national institute of allergy and infectious diseases. let me start with you, dr. fauci. how could this happen with someone in protective gear? that's what's so alarming about this. >> well, certainly there has to have been an inadvertent innocent breach of the protocol of taking care of a patient within the personal protective equipment. that extremely rarely happens. we been taking care of ebola patients since 1976. groups like doctors without borders who do that almost never have an infection because of the experience of doing this, so this happened certainly because there was and the cdc is trying to find out now just what that breach was but this was a breach in protocol, unfortunate for this very courageous health care worker. >> do you know anything about this health care worker, what the job was? >> we know that the person did have direct contact in taking care of the patient. >> was it a nurse? was it -- >> i'm not sure. i'm hearing it's a nurse but i d

dr. richard besser. back with us tonight. in this case, rich, this nurse was wearing protective gear. so, if there was an opening on the skin, with the gear, how would she catch ebola on the skin? >> reporter: a couple ways. if there was a cut, it could be a direct infection. otherwise, if she touched her eye, her nose, her mouth with that hand, she could get infacted. >> a lot of people are going to wonder if she had ebola on the skin, how long is it contagious, dangerous on the skin without you knowing about it? >> reporter: it could be several hours. >> now in the meantime, this patient is in dallas tonight, that nurse,ed and with the breakdown there, where are hospitals that are absolutely ready for this in this country? >> reporter: well, there are four special bio containment hospitals, facilities around the country. look at this map. montana, nebraska, georgia, maryland. what i like about those places, for years, they've been practicing for just this kind of event. >> but there are only four hospitals. some people wonder, why not get the patient there or get the teams from one

dr. richard besser has been in the ebola hot zone covering the story for us. he just returned to the u.s. this weekend. he spoke to rebecca jarvis about whether the precautions being taken are enough. >> i had my temperature taken three times before i got on the plane in liberia. someone looked me in the eye to see if i looked sick. i had a detailed questionnaire. that makes me more comfortable that people that are sick are not getting on the plane. if i were if i didn't tell honestly like mr. duncan about exposures to ebola, that would be another slip in the system. that's why we have to knock it out in west africa so we're safer here. >> we'll have much more from dr. besser later on "good morning america." >>> a second new jersey preschooler is being monitored for enterovirus. after a boy in a different class died of the respiratory illness. eli waller's death is the first linked to enterovirus 68. he went to bed with no apparent symptoms other than pink eye and never woke up. his school district is now tracking all children who are sick. there have been con

dr. besser standing by in the hot zone, answering your questions tonight. >>> also this evening, the newars surrounding that other mystery illness, striking american children. and tonight, the new cases of paralysis. we are with the doctors witnessing it, what they're telling every parent to look for. >>> the danger on the field. three high school football players dying in just the last week. the stunning view from inside a helmet. >>> and, look at this tonight. the break-in caught on tape and the mistake so many of us are making. and the one thi

dr. rich besser joins us now. you opposed the quaun teen. why? >> well, the health care workers don't pose a risk. there are been hundreds and hundreds of workers in the region and returned to the countries. and you cannot share the infection unless you are sick. monitoring for fever works. we need to celebrate them as heroes so more people will go over. >> we heard from a lot of people out there, the viewers who support the quaun teen on the nurse. is there a middle ground? >> i understand the fear. we need the leaders to lead, not follow the pack. we are getting mixed messages. we hear the doctor pose nod risk but they want to the every place he visited and cleaned it up. they are moving from self-monitoring sof fever and every health care worker that returns will be monitored by a health department. >> dr. besser, thank you very much. >>> we move on to the high scol shooting in washington. students, the families and the community trying to understand how a boy just crowned homecoming prince could launch such a violent attack on his best friend

dr. besser and another doctor -- everybody get an the same page, please. >> dr. besser is busy with ebola right now. >>> we've got a surprising admission to tell you about. a story we've been keeping up with here. a special type of highway guard rail. and the makers of that guard rail now speaking ot. those rails don't perform properly. >> the company that makes them has always denied that. as abc's brian ross reports. >> oh, my god! >> reporter: despite a growing number of hourific accidents in which guard rails have speared through cars. the company that makes the guard rails, trinity industries of texas, has maintained there's no safety problem. what's called the end terminal of the guard rail is supposed to absorb the impact, curling or peeling the railing off to the side. trinity has used this crash test video to persuade government officials the guard rails work as designed, even after modifications to the original design. in a federal glous marshall, texas, the company reveals for the first time the existence of five crash tests where the modified guard rai

dr. besser went through the same screening that duncan did when he left the country.his temperature taken. normal. >> fever, no, headache, no. >> reporter: and filled out the same questionnaire, but to the question, have you been in contact with an ebola patient, duncan said "no." and then, he boarded. while in the past few months, 77 other passengers in the region have not been allowed to take their flights. the tsa announcing stepped up screenings at five airports starting saturday. passengers at these airports, where 94% of travel earls from west africa land in america, will experience screenings just like what duncan went through in liberia. >> right now, the bottom line of what we're talking about today is that we're stepping up protection for people coming into this country and for americans related to travel. >> reporter: travelers from countries like sierra leone and liberia will have their temperature taken and fill out a questionnaire. but for airline workers, this screening apparently not enough. just hours ago, air serve cabin cleaners nationwide walked of
