WENDY ROSS, CNN HERO: As a developmentally pediatrician I do a lot of diagnosing of autism. When I heard that my families were afraid to go out, I felt like I needed to find a way to help them. Ever everyday experiences like going to a baseball game can be a challenge for kids with autism. Music, lights, the noise, there's a lot of unexpected sensory things happening.

How are you?

Good. How are you?

Are you ready to go?

I worked with the Phillies to train all 3,000 people that work at the ballpark.

Much of it is a social disability. So it needs to be addressed in the community. We prepare the families with story book of experiences that may happen at the park. And then we provide supported game experiences sort of like a safety net. If you start taking step outside of your door, your world gets bigger and bigger.

UNIDENTIFIED FEMALE: He's having fun one success means more success.

ROSS: It's about more than a game. It's about opportunity.

UNIDENTIFIED FEMALE: Hopefully there will be zoos in our future and aquariums. The world is our oyster.

ANA CABRERA, CNN ANCHOR: Hello, I'm Ana Cabrera, you're in the CNN NEWSROOM. Thanks for spending part of your weekend with me. In the U.S., New York City, of course, is now the Ebola epicenter and we have some new reaction from the New York City officials as well as federal officials responding to this new mandatory quarantine imposed by New York and New Jersey for those health care workers now flying into JFK and Newark.

I want to get right out to Elizabeth Cohen with more information on this. Elizabeth, what are you hearing?

ELIZABETH COHEN, CNN SENIOR MEDICAL CORRESPONDENT: Ana, what I'm hearing from federal and New York City officials is that they were stunned, completely surprised, when the New York and New Jersey governors Christie and Cuomo said that they're going to start quarantining health care workers when they return from West Africa.

They said there was no consultation, public health experts weren't consulted. One of them said they fear it's being done more for political reasons than for scientific reasons and, you know, Dr. Mary Bassett who is the health commissioner here in New York City through a spokesperson she said, "Look, I am worried that this is going to discourage health care workers from going to Africa and helping that completely reverses everything we've been trying to do to help this outbreak. Ana?

CABRERA: We already heard from one of these health care workers returning being quarantined. Some good news about that, by the way, this New Jersey health care worker, we now know has tested negative for the Ebola virus. She faced a mandatory quarantine after arriving in Newark from West Africa where she helped treat Ebola patients. But the story doesn't end there.

In fact, according to her new op-ed in the "Dallas News" today. Kasi Hickox (ph) knew nothing about the quarantine and she hasn't happy about it. Here's an excerpt from this. She said "I have been quarantined in New Jersey. This is not a situation I would wish on anyone and I am scared for those who will follow me. I am scared about how health care workers will be treated in airports when they declare that. And that have been fighting Ebola in West Africa. I am scared that like me they will arrive and see a frenzy of disorganization, fear and most frightening quarantine."

So, Elizabeth, you know, you've been following all of these developments. We're hearing now from the health care worker. This is certainly a fear that we're hearing from doctors that it could discourage other health care workers from even going into West Africa if they know they're facing this quarantine and this seems to be maybe backing that fear up.

COHEN: That's right, Ana. This Kasi Hickox, a nurse, is now stuck in a New Jersey hospital against her will, based on some pretty thin evidence that she was even sick. You've seen these - these scanners. They kind of look like big white guns. They're put to the forehead and they read out a temperature. Well, study have shown that those are not as reliable as an oral thermometer and she had one high reading and then she had lots of normal readings with a much more reliable thermometer though she was sent to the hospital. And then she wrote this in her op-ed piece.

She said when she got to the hospital "the infectious disease and emergency department doctors took my temperature and other vitals and hooked puzzled." Your temperature is 98.6, they said. You don't have a fever. But we were told you have a fever so this woman who is not sick. Who has now tested for negative Ebola is stuck in this New Jersey hospital. I've reached out to Governor Christie's office and I've gotten no response to explain why are you holding this woman. All she did was go try to help save lives in Africa.

CABRERA: Are you hearing anything from either governor's office, Governor Cuomo's or Governor Christie, about this new quarantine and the reaction from the health care workers about it?

COHEN: No, I'm not hearing anything. I've reached out to both governors' offices as well as other spokespeople for them and haven't gotten any calls back.

CABRERA: What's the latest on the condition of the New York Ebola patient, the doctor, who we now know is also fighting for his life?

COHEN: Right. So Dr. Spencer who's in the hospital behind me, we're told that he's in stable condition. He's in isolation. We're told that he's in pretty good shape. He's able to talk. He's been on his cell phone. So it seems that hopefully this is yet another Ebola patient in the United States who will survive, you know, Ana as you know there have been many U.S.-Ebola patients who have survived. Only one has passed away Thomas Eric Duncan and he got his care very late in the game, unfortunately.

CABRERA: Right. These latest cases they caught early and that is good news. Elizabeth Cohen, thanks. And we appreciate you staying on top of it for us.

And now another big story, the school shooting near Seattle, a homecoming prince opening fire in a high school cafeteria. We now know his targets were not random. Freshman Jaylen Fryberg reportedly shot two of his own cousins. He also shot two 14-year-old girls, both in the head. The mystery of a motive still not completely solved.

Classmates say Fryberg was a popular football player. Just a week ago, he was just elected homecoming prince for his freshman class. Days ago, Fryberg was smiling, even dancing at football practice we are told. What lurked underneath that sunny demeanor, did Fryberg signal his apparent rage in tweets leading up to Friday's rampage? We'll read some of the disturbing new messages.

And we're also learning more about the victims, fighting to stay alive. Doctors tell CNN things are very touch and go for the two injured girls. Listen.

(BEGIN VIDEO CLIP)

DR. JOANNE ROBERTS, CHIEF MEDICAL OFFICER, PROVIDENCE REGIONAL MEDICAL CENTER: We've seen tears. We've seen anger. They are just - just grieving. Right now I think they are just settled in. Things are quiet. They know the circumstances. They're hoping for the best.

But the next three days are going to be crucial. These young people are being monitored moment by moment. They have a nurse at their bedside constantly. A doctor is very nearby constantly. All the neurosurgeons have rounded this morning and they'll be here rounding throughout the day. But this will be a process that take - we won't know a whole lot more for the next two or three days.

(END VIDEO CLIP)

CABRERA: We are covering every angle of this deadly school shooting.

I want to bring in national correspondent Susan Candiotti, live outside Providence Regional Medical Center where those two girls are still battling. Susan, I know you spoke to an acquaintance of Jaylen Fryberg, the gunman, about some recent trouble that Fryberg may have faced. Tell me about what you've learned.

SUSAN CANDIOTTI, CNN NATIONAL CORRESPONDENT: Right. The motive for all this is still a mystery and investigators if they know what it is, they haven't yet released it. But as you mentioned, I spoke to a schoolmate of the shooter in this case Jaylen Fryberg, and he's a junior and he speaks to this young man on occasion.

Coincidentally they had a brief conversation at the start of the school day on Friday. And one of the things he said they talked about was his recent suspension from school. Fryberg had just come back. He was punished for apparently being involved according to students in a fight that happened at a football practice after some students allegedly made some derogatory comments about him. And here's what the student said of their conversation -

(BEGIN VIDEO CLIP)

NATHAN HECKENDORF, KNEW JAYLEN FRYBERG: It was a moment just a kind of - just a follow-up on what was going on in his life, you know, you know, like I said, I wasn't - I haven't ever been that close to him but, you know, I've spoken with him and talked to him like I do to other people that I see around school and I just told him, like I said, to talk to me, come talk to me if he ever needs anything and, you know, and his final words that he said to me about what happened with the fight, you know, he said it was an act of anger. Or it was an act of aggression and he should have used his words and those were the last words that he had really spoken to me and it really kind of hit me pretty hard.

(END VIDEO CLIP)

CANDIOTTI: And so investigators we can tell you have now cleared the scene at the school. They were working there until close to 11:00 last night gathering evidence. And wrapping up interviews they conducted with students and teachers and staff earlier in the day on Friday. This morning the school back open again only to allow students and staff to come back in and pick up any belongings that they left behind. The school is closed for this coming week. And we do expect, Ana, some new information from the medical examiner as well as a statement from the tribe to which Jaylen Fryberg belonged, the Talaylo (ph) tribe, on the reservation later this day. Ana?

CABRERA: Susan, we mentioned these tweets and how social media is one of the areas investigators are now turning to, to try to figure out why he went on this attack. And one of those tweets from Tuesday reads, "It breaks me, it actually does. I know it seems like I'm sweating it off but I'm not. And I never will be able to." Are you learning any more about what prompted tweets like that?

CANDIOTTI: You know, it's really speculation at this point. Students are talking about it quite a bit, but there are different versions of what it might have been receiving to. Could it have been this fight he was involved in. Suspended from school? Might it have been from a possible break-up that he may have had with a girlfriend? It's really unclear or simply anger over something else.

So, these are the things that are becoming very important to investigators as well as, of course, hands-on interviews with the students who were with him that day and who are friends of his. Everyone trying to piece this together.

CABRERA: There are a lot of questions for sure. Susan Candiotti, thank you so much.

Coming up, the Marysville mayor is going to join us live.

(COMMERCIAL BREAK)

CABRERA: People in Marysville, Washington, are dealing with so much grief. So many questions after a homecoming prince went on a shooting rampage in his high school cafeteria. My next guest is the mayor of this town where the tragedy occurred. Marysville mayor Jon Nehring tried to soothe his community yesterday when he said this -

(BEGIN VIDEO CLIP)

MAYOR JON NEHRING, MARYSVILLE, WASHINGTON: My heart right now goes out to the community. Our thoughts and prayers are with primarily those who have lost loved ones today. Also those who have injured loved ones right now and everybody involved at Marysville Pilchuck High School and also we want to extend that. We've got kids all over this community that know the kids involved and our hearts are with them and their families. This is a true community tragedy for the Marysville Tulalip community.

(END VIDEO CLIP)

CABRERA: No doubt about it. Joining me now is Marysville mayor Jon Nehring. Mayor, thanks for making time for us. We know you are very busy especially during this difficult time. Tell me, how did you find out about yesterday's tragedy? Where were you at the time?

NEHRING: I was at city hall. I had just finished up a transportation meeting that I was involved in and then at about 10:42, 10:43 our chief administrator officer came in and told me about it and we grabbed everything and headed right over to the command center immediately.

CABRERA: Now that you've allowed things to kind of sink in, I imagine initially it's all just shock and whatever reaction you can get out there. What is the plan in terms of now coping with this tragedy?

NEHRING: Yes, you know, one thing I can tell you about Marysville, we're a tight-knit community and this community has bounced back from things before. This is probably the most significant thing that we've faced at least in a real long time. But Marysville will bounce back and that will what defines us. It really started yesterday with the response of our EMS and police personnel, the professionalism right on through the evening with the candlelight vigils and just thousands of people coming out and crying together and hugging and taking the very initial steps to recovery from this and of course, right now, as you played at the outset, our main concern and our thoughts and prayers are with these kids fighting in the hospital and with all the families who have lost injured loves ones.

CABRERA: When something like this happens, everybody tries to make sense of it. I know you, mayor, are a father of three children yourself. How did you talk to your kids about this shooting?

NEHRING: You know, it is tough. And the first thing I did is just hugged my kids, you know, and I mentioned last night that sometimes I think this is - it's needed for us to re-evaluate our priorities. We were rushing around yesterday morning. I don't even think I said good- bye to my kids before they left for school.

So, that reoriented me a little bit. But particularly my youngest son who is at the other high school in our community but went to middle school just last year with pretty much all of these kids and was close friends with a couple of the girls. And so, you know, it's a tough thing for him. It's a tough thing for all the kids in our community not just my kids but all of them. Yes, it was good to get home and hug them late last night and spend a little bit of time talking it through.

CABRERA: We heard that Marysville police did S.W.A.T. training. Took place at the school district center just days before this shooting. Is that a regular occurrence? Do you think that helped police in terms of responding to this incident?

NEHRING: Absolutely. Our police have over the past couple of years, over the past several years, have held regular training on these type of incidents with all of our schools and I have no doubt that that is what helped with the rapid response and the ability to evacuate and complete two full sweeps of the school and find additional kids that were still on lockdown and even a couple who had minor injuries and so that training paid off and I can't say enough about our EMS and our police personnel and the professionalism and that will continue in the days and weeks ahead and the partner agencies.

I don't want to forget all the partner agencies that came in and helped us. Surrounding communities. The sheriff's office. We just received so much support on this. Even got e-mails from as far away as Norway and Uganda. But it's great for our community.

CABRERA: That is great to hear that you're getting that outpouring of support. One last question for you. We've heard that perhaps a staff member or an employee in that school tried to stop the gunman, approach the gunman? What can you tell us about that? What have you learned?

NEHRING: Yes. We've heard the same thing. Apparently there was - I believe a first-year teacher who did step in and in some way contribute to ending this event. And so I would just say, you know, that just shows us once again there's all these heroes in this type of a thing even though it's a horrendous tragedy and she appears to be one of those heroes as I'm sure we'll find out more, too, about some of the students and what happened. But, yes, it's something that we have - we're really proud of.

CABRERA: Right. You said we're still trying to learn all the details about the facts of the case. Have you had a chance to talk to that first-year teacher?

NEHRING: I have not, no. That's the type of thing that, you know, we'll give them some room to recover from this and deal personally with some of these things, and follow-up with some of the families and whatnot at an appropriate time. But right now our priority is just getting everybody back home with their families and get some time to digest everything that's happened here over the last 24 hours.

CABRERA: Absolutely. Well, Mayor Jon Nehring, thank you so much for being here. Best of luck. Our hearts and our thoughts and prayers are with you and your community there.

NEHRING: We certainly appreciate that, Ana. Thank you.

CABRERA: Thank you.

In the midst of two lone wolf attacks in just one week, ISIS now ramping up efforts to recruit jihadis from Canada. The details right after this.

(COMMERCIAL BREAK)

CABRERA: We are now learning more about the gunman who opened fire on Canada's Parliament Hill killing a soldier and we now know Michael (INAUDIBLE) was a recent convert to Islam and had ties to other jihadists.

(BEGIN VIDEO CLIP)

BOB PAULSON, RCHP COMMISSIONER: We have learned through the current investigation that this individual has been in Ottawa since at least October 2nd, 2014. That he was in town to deal with a passport issue but that he was also hoping to leave for Syria.

(END VIDEO CLIP)

CABRERA: So this revelation and another deadly attack against a different soldier earlier in the week in Canada raising questions about ISIS and its seemingly successful recruiting tactics in the west. Randi Kaye takes a look at how this terrorist group is doing it.

(BEGIN VIDEOTAPE)

RANDI KAYE, CNN CORRESPONDENT (voice-over): You might think is a commercial from the Tourism Board of Canada. It's not. It's actually a recruiting video from ISIS. Aimed at convincing extremists to join jihad in Syria.

UNIDENTIFIED MALE: I'm your brother in Islam here in Syria. I originally come from Canada.

KAYE: He is the ultimate pitchman for ISIS. Andre Poline, a Canadian convert who changed his name to Abu Maslan (ph). Listen as he tells the camera in this 11-minute video before he joined ISIS he was just a normal Canadian teenager.

UNIDENTIFIED MALE: I watched hockey. I went to the cottage in the summertime. I loved to fish. I wanted to go hunting. I liked outdoors. I liked sports.

UNIDENTIFIED MALE: He moved during the battle like a man that did not know death.

PAUL CRUICKSHANK, CNN TERRORISM ANALYST: The message of the video is that you need to emigrate from western countries especially Canada to Syria because it's only there that you can live properly as a Muslim.

KAYE: That message is resonating. The Canadian government has identified 30 Canadians now fighting in Syria and Iraq. Another 100 fighting in places like Yemen, Pakistan and Afghanistan.

(on camera): The government claims to know the identification of all of those fighters. Already 80 of them have returned home and could pose a potential terrorist threat.

(voice-over): Why is ISIS targeting Canada? Because of its growing problem with radicalization.

CRUICKSHANK: Too many young Canadian Muslims have felt alienated from mainstream society and have looked to radical ideologies for a sense of identity and purpose. There's a clamor amongst people from these backgrounds, extremist backgrounds in Canada, extremist ideologies to go and travel to Syria and Iraq and join this Islamic caliphate as they see it.

KAYE: And it's not just fighters ISIS is hoping to recruit. On the video the pitch goes well beyond that.

UNIDENTIFIED MALE: We need the engineers. We need doctors. We need professionals. We need - we need - we need volunteers. We need fund- raising. We need everything, you know, there's a role for everybody. You can even come here and help rebuild the place.

KAYE: Or you can come here and die just like Andre Pouline, as he rushed into battle at a military airport, he was killed by explosives last year far from Canada and the country he once loved.

Randi Kaye, CNN, New York.

(END VIDEOTAPE)

CABRERA: The attack on Canada leading to some serious questions here in the U.S. about border security. (BEGIN VIDEO CLIP)

MIKE MORELL, FORMER CIA DEPUTY DIRECTOR: I'm much more concerned about the Canada border, Charlie, than I am the Mexican border because it's much easier to come across that border.

I am now more worried about a terrorist threat in the United States than I have been for a long, long time.

(END VIDEO CLIP)

(COMMERCIAL BREAK)

CABRERA: New concerns over U.S. border security in the wake of that attack in Ottawa this week.

And joining me now Bob Baer, CNN national security analyst and former CIA operative.

Bob, we know there are more than 18,000 Border Patrol agents on the border with Mexico, but just over 2,000 on the significantly larger border with Canada. What's your opinion? Is the U.S. focusing on the wrong border?

BOB BAER, CNN NATIONAL SECURITY ANALYST: Well, I think really both borders are a problem. There are a lot of smuggling, of course, going back and forth, a lot of drugs going back and forth. There are connections in the Middle East you can make, arrangements to get somebody to take you across the border, both Canada and the United States. Nonetheless, nothing has come from either border so far in the last decade. So, it's really very much an aspirational thing at this point but I think we should worry about those borders and we should worry about who's coming into Canada and who's coming into Mexico. We need to share databases with those countries and to do traces on them, frankly.

CABRERA: Why isn't that happening already?

BAER: You know, the databases aren't unitized. The Mexicans and the Canadians are reluctant to give the FBI access to them at this point which I think is unfortunate. In the same way with reservations, we can track anybody coming to this country on the two reservation systems but the same doesn't go for Mexico and Canada. And unless you get a heads-up on these people traveling, you really can't do a full investigation on them.

CABRERA: We learned earlier this week that U.S. military folks that are in Canada will not be wearing their uniforms anymore. Just out of safety concerns after these two attacks in one week against soldiers. Isn't this giving the bad guys what they want?

BAER: Well, it's a precaution and they have to take it. Because is can't hit Americans anymore in their area in the so-called caliphate so they're going to move abroad. And I do think, and there's no firm evidence on this, they're going to come after American targets wherever they can get to them and the closer they are to the United States itself, the more fear it's going to cause and concern and in as much as you can make predictions on this I think it's where it's going.

CABRERA: Better safe than sorry as you just said. Thank you so much for being here and we appreciate you sticking with us over a couple of hours.

BAER: Thank you.

CABRERA: It's one of the biggest academic scandals to hit college sports in a decade. A cheating scheme at the University of North Carolina. Now, one of the coaches is speaking out. We'll hear from him next.

(COMMERCIAL BREAK)

CABRERA: OK. Imagine being able to head off to college. You enroll in certain classes that you never even attend and still get good grades? Well, that's exactly what investigators claim student athletes did at the University of North Carolina for 18 years.

Sara Ganim is joining us now to discuss this.

Really stunning revelation that was revealed during the course of a long investigation. Why does this even happen to begin with?

SARA GANIM, CNN CORRESPONDENT: Yes, so what they found was that this all started with one professor's assistant who was sympathetic basically who students who weren't the best and the brightest. That's a quote from her. She was also a huge fan of UNC basketball. She would sometimes miss work if they lost.

And the athletic advisers and academics -- yes, academic advisers in athletics began to take advantage of this, pushing athletes into these classes when they were on the brink of eligibility so that even if they couldn't compete in the classroom, they could still compete on the field.

CABRERA: I can't imagine what would necessitate that. I mean, I was a student athlete in college. I know what kind of resources student athletes are given -- tutors, computer labs, to be able to succeed academically. I mean, what are coaches saying about this?

GANIM: Well, it's interesting. So everyone is asking, do the coaches know if the advisers knew, do the coaches know? And some of them did. What the report found was that former head football coach John Bunting, he admitted he was very honest, he knew about it. His successor Butch Davis, he admitted some knowledge of the paper classes. He was fired in 2011 after this was all revealed.

Now, I wanted to know, Dean Smith, he is a legendary basketball coach in that state. He was at UNC for 36 years. He's an icon.

Anyone who follows basketball, college basketball knows of Dean Smith. The report found no findings on him and his staff so no evidence that he knew about this. He retired in 1997. These classes started in 1993 which coincidentally is also a year they had a basketball championship.

But the current head basketball coach Roy Williams, he is adamant that he knew nothing about this. And he actually just spoke about this just reacted to this report and I want you to hear what he had to say.

(BEGIN VIDEO CLIP)

ROY WILLIAMS, UNC BASKETBALL COACH: I didn't like the fact that we had so many guys in the same major. I didn't think it was -- made sense. People have different things that they like. We'd go in had home at that time even more strong and say what would you like to major in and we allowed kids to choose any major.

After our second year, I think the rest of that time kids that we recruited had one guy majored in African-American studies because I didn't like the clustering. And, yes, they made very good grades. But I want our guys to be able to choose what they wanted to choose. Things that have happened for a long time, it's very disappointing.

We're all really extremely sad about it. I'll always be sad about the image that we have right now around the country. We've had one of the greatest images we can possibly have, and we're going to work as hard as we can possibly work to have that image be back to where it was. There's not been a day in my life that I haven't tried to do the right thing academically and get my kids to be concerned about the academic side.

(END VIDEO CLIP)

CABRERA: All this being said, 18 years this was going on, what are the repercussions?

GANIM: So, the NCAA is taking another look. It previously said it was an athletic scandal. But now, they are coming back with a full copy of this report, 131 pages and almost 900 pages of supplement documents, e-mails, they could very easily come back and say some of the wins were not legitimate.

I think at least two basketball championships, men's basketball championships, are definitely in jeopardy in 2005 and 2009. That was the height of the scandal when most of the students enrolled from these classes were taking them.

CABRERA: Crazy. Sara Ganim, thanks.

GANIM: Of course.

CABRERA: In New York, health officials are now putting a time line together that traces and retraces the footsteps of Ebola patient Craig Spencer. We'll show you how they are putting this timeline together next.

(COMMERCIAL BREAK)

CABRERA: New York City doctor, Craig Spencer, brought the Ebola virus back with him from West Africa from treating patients there. Well, now, health care officials are trying to find out exactly where Dr. Spencer's been and who he may have exposed.

Here's CNN's Jason Carroll.

(BEGIN VIDEOTAPE)

JASON CARROLL, CNN NATIONAL CORRESPONDENT: Dr. Craig Spencer's apartment in Harlem is sealed, off limits to all except health department officials who sent in experts to decontaminate his unit and its content, all of this as so-called medical detectives piece together Spencer's whereabouts prior to being diagnosed with Ebola.

DR. MARY BASSETT, NYC MEDICAL COMMISSIONER: We've been tracking down and seeking to account for every minute since 7:00 a.m. on October 21st.

CARROLL: Spencer returned to the United States on October 17th, after treating Ebola patients in Guinea. Feeling fine, he was checking his temperature twice a day.

On Tuesday, October 21st, 7:00 a.m., again, no fever, but Spencer tells investigators that morning he was feeling fatigue and exhaustion. Still, around 3:00 p.m. on Tuesday --

(on camera): Spencer stops here in the Greenwich Village at the meatball shop, it's a popular chain here in New York City. As of Thursday afternoon, the meatball shop, but there is a sign on their front door that says, by tonight, they will be back open.

(voice-over): At 4:30 p.m. Tuesday, he heads to the High Line, a popular elevated walkway on the Manhattan's West Side. He stops here at High Line's Blue Bottle coffee stand.

FELIPE SAINT MARTIN, MANAGER, BLUE BOTTLE COFFEE: The Health Department came here this morning and just to make sure that we were safe. I don't think anyone is feeling unhealthy. Everybody is healthy and happy.

CARROLL: Fifty-thirty p.m., Spencer takes the one train back to the 145th Street station near his home.

Wednesday, October 22nd, still no fever. One o'clock that afternoon, he goes for a three-mile-run along Manhattan's Riverside Drive and West Side Highway.

Fifty-thirty early Wednesday evening, he hops on the subway. Destination: Williamsburg, Brooklyn.

(on camera): Spencer took the A-train and then the L-train to Williamsburg. Medical detectives know that. They also know at that point, he was feeling fatigued but he still was not running a high temperature.

Well, the A-train, like most trains in New York City, can get pretty crowded, but health officials say when Spencer took the train, he was not exhibiting any symptoms, and therefore, they say, he was not contagious. (voice-over): Two of Spencer's friends join for the subway ride to

The Gutter bowling alley in Williamsburg. The Gutter now temporarily closed for cleaning.

UNIDENTIFIED FEMALE: I definitely would not voluntarily go there right now.

CARROLL: Wednesday, 8:30 p.m., health officials say Spencer left the bowling alley and took the taxi service Uber.

Ten-fifteen a.m. Thursday, Spencer reports a temperature of 100.3 to Doctors Without Borders and the city health department was notified. He's immediately transferred to Bellevue hospital and isolated. City officials confident Spencer was not widely contagious.

MAYOR BILL DE BLASIO (D), NEW YORK: Casual contacts cannot lead to acquiring this disease. The only threat is if one has come in contact directly with the bodily fluids of someone who has this disease.

CARROLL: Jason Carroll, CNN, New York.

(END VIDEOTAPE)

CABRERA: Our thanks to Jason.

Just a quick update to Jason's story there. After a thorough cleaning, The Gutter bowling alley in Brooklyn has indeed reopened.

And joining me now is CNN medical analyst, Dr. Xand Van Tulleken.

Dr. Van Tulleken, you know, a lot of people are concerned because New York is such a big, busy city. We mentioned in that report that he was feeling fatigue prior to feeling -- or reporting that fever.

So, if he's feeling fatigue, does that make him potentially infectious, and contagious?

DR. VAN TULLEKEN, CNN MEDICAL ANALYST: Well, what we know is the virus will have been slowly replicating in his bloodstream and in his body through the whole period since he acquired it and developed a fever and that means that potentially his bodily fluids would have virus which could be contagious but I think it's really important to say that the viral levels are so low that I think the chance of him infecting anyone are as close to zero as you can reasonably say. I'd never say there's no chance at all, but I would say there's about as much chance of catching Ebola from him on the subway, there would be from catching HIV from someone who was HIV positive, as possible. If they cut themselves, if you had a big exposure, but I think it is incredibly unlikely.

So, that's -- the contact tracing is partly to make sure there was no big instant, he didn't cut himself open. He didn't get drunk and vomit, anything like that. And we -- as far as we can tell nothing like that has happened.

So, I think no one in New York City other than his very close contacts and particularly his fiance are likely to have been exposed and even they, I think, are fairly safe.

CABRERA: And none of them are showing any symptoms at this point.

VAN TULLEKEN: And we know that from other exposures. Thomas Eric Duncan and Patrick Sawyer both had fevers, exposed their families, other peoples on airplanes, and actually in the early stages didn't infect anyone.

CABRERA: Doctor, say with me. We're going to talk to you on the other side of this break.

New York and New Jersey now imposing new mandatory quarantines for anyone traveling from a country in West Africa, been treating patients with Ebola. Will this prevent health care workers from wanting to travel to West Africa and help eradicate the virus?

We'll speak with a doctor who is about to go there, as well as Dr. Van Tulleken, when we come back.

(COMMERCIAL BREAK)

CABRERA: They're risking their lives, sacrificing their livelihoods. Doctors who are traveling to West Africa to provide much-needed help there in the Ebola hot zones.

Our CNN's Nick Valencia spoke to one man who we're going to talk to just on the other side of this story who has been preparing to go to Liberia. He leaves in just ten days.

But, first, meet about how he's training to go there and we'll talk to him about the mandatory quarantine now imposed in New York and New Jersey, and see if it changes anything in his plans.

(BEGIN VIDEOTAPE)

NICK VALENCIA, CNN NATIONAL REPORTER (voice-over): In an abandoned building in Aniston, Alabama, healthcare workers are getting a crash course on treating Ebola patients in the hot zone. This group of American doctors and nurses will soon head to the three countries in West Africa affected by the Ebola outbreak. Dr. Phuoc Le will go to the Liberia. He says the training he gets today will mean the difference between life and death.

(on camera): We saw you struggle a little bit as you took out --

PHUOC LE, ASSISTANT PROFESSOR, UNIVERSITY OF CALIFORNIA SAN FRANCISCO: Yes it's not easy. It's not easy. And I'm -- that was a large size and I'm not a large guy, but still I could not get those coveralls over my shoulders without really touching the outside, which is the contaminated side. I was supposed to only touch the inside, which is the clean side. And I just couldn't do it. So, that's -- I'm going to practice again and again.

VALENCIA: The training is modeled after procedures used by Doctors Without Borders. Three days of intense practice in dealing with drawing blood, cleaning vomiting, and even patient burial. A lot of it is trying to limit the inevitable human error says CDC trainer Dr. Patricia Griffin.

DR. PATRICIA GRIFFIN, INTERIM COURSE DIRECTOR, EBOLA TREATMENT UNIT TRAINING COURSE: The first thing you want to do is get rid of all that bulky gear. But you have to have the muscle memory of having done it before, of knowing that you can do it, safely and knowing that it has to take a little longer than you would like it to. And you have someone there guiding you through it so you stay calm and just get it all off and then you walk out knowing that you are safe.

VALENCIA: Dr. Le thinks a lot about safety with a wife and two-year- old child back at home in Northern California. He says he's anxious about his impending trip, but for him his concern is outweighed by compassion.

LE: Whoever tells you that they're not anxious about going to Liberia and working in an Ebola unit I think is delusional. I'm very nervous.

VALENCIA (on camera): Then why do it?

LE: Like I said, it goes back to this idea of the solidarity and equity. It's kind of like if you are a fighter and you signed up to fight fires and there's a fire, you should go fight that fire.

VALENCIA (voice-over): Nick Valencia, CNN, Aniston, Alabama.

CABRERA: What a guy.

Let's talk more about this and the news that more stringent airport procedures will begin in New York and New Jersey.

I'm joined by assistant professor at UC-San Francisco, Dr. Phuoc Le in Los Angeles, the doctor you saw there in Nick Valencia's story.

Also here with me in New York is CNN medical analyst, Dr. Alexander Van Tulleken.

Dr. Phuoc Le, I want to start with you.

We mentioned those procedures, the mandatory quarantines that go into effect for those returning to New Jersey and New York. What do you make of that?

LE: Well, Ana, you know, we as health care professionals and scientists, we know the science behind it. And as the other doctor mentioned, the risk to the general public is infinitesimally small.

However, we are also not governors and mayors of large populations. So, their considerations are much broader than ours. And so, with the input of the CDC and other health professionals, if their decision that for the best of California -- of New York and New York City is to impose that quarantine on returning health care workers, then I have no opposition to it.

However, I do want to say that, like you mentioned, people are giving up their livelihoods to go and volunteer to serve on the front lines. When they come back and are quarantined for those 21 days, I urge the hospitals and their employers to do as much as they can to support them so that they don't lose health benefits or salary because they went out and did that volunteer work.

CABRERA: That is such a great point, and we really do salute your bravery and dedication to helping the people in West Africa. We know you leave in just 10 days from now and you telling us you are still planning to go despite these new mandatory quarantines is really a valiant thing I think.

Dr. Van Tulleken, I want to ask you in terms of people you are talking to in this medical industry, will this keep doctors from traveling to West Africa? I know that's one the criticisms to what New York and New Jersey governors have done with these quarantines.

VAN TULLEKEN: Yes, I think there are two issues. Firstly, it is a disincentive to go. I mean, I really do think that people doing the kind of work that Dr. Le are doing are absolute heroes because they are making us safer. It's not that they are just doing good work out there and responding to a humanitarian crisis. The only way we get less Ebola in New York is by having less in West Africa.

But the other thing is, it's not been thought through very carefully. We don't know where people are going to be quarantined, we don't know exactly how they're going to be supported and this encourages people not to tell the truth.

In the end and we've heard the governor say voluntary quarantine is not be enough. In the end, it will be voluntary. There's not going to be a man with a gun keeping people inside. We don't have the facilities to house a large numbers of people for 21 days at a time, at least in the kind of comfort that they deserve.

And so, the screening at the airport is going to be questions that you have to answer, and not all are going to be responsible doctors from Doctors Without Borders or other organizations. So, you have a real concern that people won't be telling the truth when they get back. And in the end, the imposition is going to be expensive and I would say completely pointless.

CABRERA: And it should be worth mentioning that that doctor, Dr. Craig Spencer, who is now battling Ebola here in New York City, he was with Doctors Without Borders an organization that has an extreme amount of experience in how to handle this whole situation with Ebola there in West Africa and doing things to the T, as we've heard our Dr. Sanjay Gupta talk about.

Let me ask you, Dr. Phuoc Le, since you're getting ready to go there, what do you make of the fact that this Dr. Spencer seems to be, being called both a hero and a villain to some degree because he came down with Ebola and he had been out in the general population prior to getting a fever? LE: Well, I don't know personally Dr. Spencer, but I do know that he

was following the protocols of Doctors Without Borders. And I have personal experience working with many physicians in that organization. I spent two months working in the cholera epidemic addressing that crisis in Haiti in 2010, and I can assure you that Doctors Without Borders as an organization is highly professional and highly committed to this work. And they are absolutely the best out there.

CABRERA: Dr. Phuoc Le, are you scared at all to go over there?

LE: Well, I just left a 2 1/2-year-old and an anxious wife to come and talk to you. So, you know, it's -- it's absolutely false if I say that I'm not anxious.

But just like I mentioned in that other story with Nick Valencia, a firefighter would be anxious to go in a raging fire that's not contained but, you know, he or she has had years of experience and training to protect him or herself and that's how I feel.

I've had many years of training. I've been in the field. I've had the CDC training. And I think I will go in with eyes wide open. It doesn't mean that I'll have no risk, but I've done everything I can to minimize that risk.

CABRERA: Well, we certainly wish you the best of luck and we hope that all goes well for you. Thank you for the work you're doing.

LE: Thank you, Ana.

CABRERA: Thank you both for joining me as well, Dr. Van Tulleken.
