i'm arthel neville time now for "sunday housecall." >> and i'm eric shawn. joining us dr. marc siegel. and author of the interpulse unlocking the secret code of sickness and health. >> and dr. david samadi, from lennox hill hospital. we're going to begin with this breaking news this morning that another person this morning happening another person in the united states has tested positive in preliminary testing for ebola. dr. siegel, hello to you, sir, and tell me, they they're reporting that there's a possible breach in protocol.

what could have happened here? >> well, first of all, we have to understand that this was a health care worker. this was a nurse that was caring for duncan. so this is somebody directly involved with ebola. ebola secretions, and she was wearing the proper suiting, but the problem is, that she may not have put it on properly. she may not have taken it off properly. up until this point, arthel, the dallas health officials have been directly involved with overseeing this. and i'm one of the people now saying i think the centers for disease control just has to take this over. because, this can happen. and you have to understand if you're putting on a suit that you're not familiar with, and we don't know all the facts yet, and you have secretions all over the place, blood, vomit, diarrhea, all the things we've been talking about on the show, if you don't follow the protocol 100% of the time you can come in contact with those secretions and catch ebola. now the test that was done is a preliminary test but it's about 95% sensitive. the cdc will confirm it.

it's causing a lot of panic but i want people out there to know this is someone that was in direct contact with an ebola patient and ebola see kregss. >> we're of all we're not blaming this health worker. it's not her fault. she's doing her job there trying to work on. dr. samadi bringing you into this. people are wondering sure this lady is a health worker, she has a family that she's in contact with. we're not trying to incite panic. you tell me your take on this. >> my take is totally different. and i think someone said that you are the only doctor so far that has talked about closing the flights out. i have no problem with america saving the world. i have no problem with us sending humanitarian, our soldiers, building all these ebola treatment centers over there. but there are a lot of rituals and burial rituals, there's a lot of things that are coming out of this, and we don't completely understand ebola. you have to tell me, how exactly the nbc cameraman got ebola just from shooting the video. you have to tell me how the nurse -- >> excuse me one minute.

>> -- how she was able to put the gloves on her face and got ebola. >> we're not talking about that case. we're talking about the nurse in the hospital here. you're going to incite panic here. >> no, no, no. -- >> on national tv. >> we don't know how this nbc camera person got it. how can you speculate. you weren't there. we don't have direct information on that. we're talking about vomit -- >> you know what concerns me? >> this is what -- >> you don't want to incite a panic. >> -- panic marc. >> dr. -- >> what concerns me is that first we're told it's body fluids. you know, vomit, blood, this sort of thing. then we're told well maybe the virus can survive on door knobs or countertops for a few hours. then the nurse in spain has the glove touches it to the musa maybe on the eyes and now sadly this nurse in texas may have not followed protocol. so the deeper question i think our viewers want to know about is, do we know exactly, dr. siegel, how is it spread? should we worry. if we're not a health care worker is it confined just to

that? can you sit on a bus or an airplane and pick up even la? is it overblown? what do we need to know? the facts, not the fears. >> well here's the facts. the facts is we've known this virus since 1976 and health care workers are always the ones most at risk and the people most in contact. what i'm concerned about the reaction out there is that when if i say to you you could get it sitting on a bus everyone out there thinks that's how are you getting it. the way you generally get it, 99.9.9% of the time is being in direct contact with the secretions of ebola. there's no evidence that that's changed. and i'm not surprised to find a health care worker getting it. someone -- you know we saw that with brantly and writebol it's the same thing. they were taking care of even la patients. they were wearing protective clothing. but they probably didn't use it exactly right. >> i want to bring dr. samadi back in. i understand dr. siegel's concern about not inciting fear. but to your point dr. samadi i think there are people out there who have that same question, why aren't we at cutting off these

flights from these countries at the moment from people coming in from those countries who where it it it it is just an outbreak there. outbreak -- okay. >> well you have to let me speak. because if i can't get the words out, then there is no issue to do this. >> yes. >> you don't have any vaccine right now. right? the vaccines are going to come in the next few months. you're not prepared to have the zmapp antibodies, all i'm saying is. until we get our emergency rooms ready. until we get our acts ready. until we understand exactly how this virus is going to spread i would tell you, mr. president, bring up those walls. control the flights out. you have to protect americans. this whole thing about, we're going to be okay. we're going to be okay. there will be no more number of ebolas. this is not to create panic in america. listen, they did a great job. cdc did a great job with sars. they had everything online, wear your mask. the airlines were ready. >> they stopped flights from

toronto. from canada. >> right. so if cdc is not worried they should not say 1.4 million people are going to be affected by this. in january. and you know how they're counting these numbers? 8,000 people diagnosed, 4,000 people dead. you tell me how they're counting these people when you have dead bodies in liberia with -- >> let me just get back to the airplane for just a second. >> we have to protect americans. >> can someone infected with ebola take tylenol, keep the temperature down, fly on a plane, get here, have tylenol, keep the temperature down, have ebola and sneak through the system. >> somebody comes through jfk and vomits, who is going to clean this up? we don't have the suits running around. i'm with him, but you have to understand, until we get our act ready, until we are prepared, keep the world away. america is a beautiful country. we're not saying ignore them. we are saying send in troops. we're sending our health care. these people our own troops can come back. we're building ebola treatment centers. we don't want people to panic. but i also as a doctor have to

take care of my patients and families. you're right this nurse probably exposed other doctors, other nurses, and this can have potential, have potential to become epidemic. we need to educate people. that's all i said. >> the issue of, i want to talk about the issue of plane flights for a second because i really want people to understand this scientifically. if the fear quotient goes high enough and the money quotient follows we're going to have to do this. we're going to have to close off the flights. we've got one patient, one person that slipped in. one person. the second one got it from him. and that person's being isolated. one person. did you know that 2,000 cases of malaria come in every year because there's 20 million new cases of malaria every year. most of them in west africa. we could close the airports for malaria, because it's getting a lot of -- it's causing $43 billion to take care of malaria patients here in the united states. $43 billion last year. >> yeah, but there's -- >> we can close flights because of malaria, there's 2,000 patients a year coming from west africa with malaria and we have

to take care of them. ebola is a very difficult virus to catch. we're going to have to close air travel off because of the fear. and the panic. not because of one case. because of the fear and the panic. and if we do that i predict and others -- >> flights -- >> fear and panic doesn't cause ebola. >> one case. >> everything starts with one case. now we have two cases. >> it's a heated debate you can tell right now between these two medical professionals how contentious this issue of ebola can be in terms of facts and fear and things going on. there's a lot of other stuff going on. we're going to get to that in a minute. we're going to deal with something that claims a million lives every year and some people don't even know if they have it until it's too late. we'll look at the fight against lung cancer. and why they say it's one of the most important issues that we can face. "sunday housecall" when we come back. i have the worst cold with this runny nose.

i better take something. dayquill cold and flu doesn't treat your runny nose. seriously? alka-seltzer plus cold and cough fights your worst cold symptoms plus your runny nose. oh, what a relief it is.

. .

back now sunday housecall. the media attention and 9 concern about ebola, it's easy to lose track of the perspective that a lot of other diseases kill a lot of more people than ebola so far. for example, lung cancer. doctors are now finding that the disease can lie hidden in a body for as long as 20 years. and that by the time a patient is diagnosed, they say, sadly it is too late. dr. samadi, what is this? you can have lung cancer and not know it? >> yes, so lung cancer, obvio obviously the deadliest cancer in the world, 1.5 million people die from this. the way we detect this today is if you have symptoms, if somebody is coughing blood or having pain, weight loss, et cetera, we would be getting the chest x-ray and c.a.t. scan. this is traditional medicine

that we have today. think about the fact this san article that came into science, british and american scientists looked at the fact if you're a smoker and you quit smoking 20 years ago, once you have the smoke attack those lung cells, you know, there are some mutations, some changes in your dna that can carry you for the next 10, 15 years and you may not have any symptoms. so now what they're suggesting which is a very exciting actually medical news is that something called liquid biopsy. what if we can find your dna, what if they find the secret of this in all those mutations and stop the disease before it becomes even apparent on our clinical data on our c.a.t. scan and chest x-rays. so i think this is a very exciting message coming in from hung cancer. it's not in the clinical stage yet but we're getting to really deep of exactly the creator of our human body, and how the secret codes are holding our dna. it's very interesting. >> what do you do now if a patient comes, can you test for lung cancer besides screening and how do you do that?

>> i think the key here is and i want to stay scientific, not political. here's the key when it comes to lung cancer. lung cancer is a big killer. it's the number two killer in the united states of men and women. and the reason is, because if you harbor it for years and by the time we diagnose it it's too late to do anything about it. now, what can we do to change that? we know smoking is a huge part of this and smoking activates you against it. you get more and more lung cancer if you smoke. but it's early in the campaign. you have some genetic abnormalities. your jeanetgenetic abnormalitie you to develop lung cancer, we can't find it. eric what the study does is it looks earlier at the genetic changes. and looks to see what your genetic abnormalities are earlier and if we can find them, we can isolate you and say, you're at high risk. you may develop lung cancer. then maybe we can get proteins to reverse the genetic changes. in the mean time, we can do c.a.t. scans of the lungs on all smokers. >> what worries me about people who have lung cancer, dana reeve, christopher reeve's wife

didn't smoke, comes down with lung cancer and dies. >> that's an important point. they talk about the genetic component of this. also there could be some other smoke like ray done in the basement that can be doing this. they also talk about secondhand smoking. but the genes are probably the start of this problem. then there are also enzymes that over the years, turn those genes into a real cancer. the whole point of this is that if you can detect those genetic markers, that causes we may not even need any kind of chest x-ray or c.a.t. scan. >> there's always -- >> there's already a gene out there called egfr that causes 15% to 20% of certain kinds of lung cancers. there's a miraculous treatment called egfr. we look for it if you have it we can give you a drug called tarsiva that mir ack russly strings your lung cancer. you get a lot of resistance to it going down. lung cancer is based on many

genetic abnormalities not just one. even if we correct that one then you develop other problems. >> look for that genetic marker. that's important. >> and the treatment. >> okay well it can be unsightly and sometimes lead to more serious problems. so what exactly is the cause of toenail fungus and what can you do to get rid of it? our doctors are back with the answer and you don't want to miss that one coming up next. i make a lot of purchases for my business. and i get a lot in return with ink plus from chase. like 70,000 bonus points when i spent $5,000 in the first 3 months after i opened my account. and i earn 5 times the rewards on internet, phone services and at office supply stores. with ink plus i can choose how to redeem my points. travel, gift cards even cash back. and my rewards points won't expire. so you can make owning a business even more rewarding. ink from chase. so you can.

now for our should i worry segment. it is our weekly segment about everything that worries us. i have toenail fungus that won't go away. should i worry. dr. siegel usually the body tells you that something else is wrong. is toenail fungus a sign of

something else going on in the body? >> i came up with this question because i get asked every single week in my office. the answer is there's different treatments for this. first people want to know can they put a cream to know can they put a cream on, can they put some kind of anti-fungal cream on or paint their nails with an anti-fungal. answer is that doesn't work that well. i've never found that to cure the problem. i found that orals work well. something called lamosil and something called sporonax. if i give it to you cyclicly for a month, stop it, another month, stop it, i have to check your liver but i find it has a big impact on toenail fungal. now they're using laser treatments in the office to offset this fungus. where does the fungus come from?

moist, areas. gyms. diabetics get it. people with slow growing nails get it. it is a big problem. >> does it mean that something else is going on somewhere else in my body? >> obviously diabetics, that's a good point, diabetic patient may be more susceptible to this and immuno compromised. typically when people walk around barefoot around swimming pool, locker rooms, fungus gets in. it's interesting, it is not the fungus of the nail. it is the fungus of the skin that gets under the nail and now because it is covering it we have a very difficult time to get to it. that's why a lot of these creams may not work because it can get under. oral medications work well but you have to be on them for six months and they cause liver toxicity. i like herbal medication, oils. this tea treated oil, or argan

oil. >> why would the tea tree/and oregano oil work if doctor siegel is saying they don't work. >> you have to keep the nail short and keep it flat on top. oil twice a day you really take a q-tip and you run around all those nails and it takes care of it. >> get rid of the bacteria. >> is it like athlete's foot? >> well, with athlete's foot it is in between the skin so you can use those sprays. those work well. laser actually is a good treatment but it is quite expensive. it costs about $1,000 a trip. but it works in about 50% to 60%. >> my mom said keep your socks on in the hotel rool. that's what i do. >> throw out those old shoes. that's where fungus usually -- >> really? >> yes. they love humidity, they love old stuff. so get rid of it. >> okay. that's interesting. haven't heard that one before. shoes and where the socks. coming up here on "sunday

house call," is there a possible cure for type 1 diabetes. researchers at harvard -- so i guess it's got to be true, it's ha harvard -- are drescribing a ne treatment. ♪ "here i am. rock you like a hurricane." ♪ fiber one now makes cookies. find them in the cookie aisle. ok, if you're up there, i coulsmart sarah.elp. seeking guidance. just like with your investments. that sets you apart. it does? it does. you're type e*. and seeking another perspective is what type e*s do. oh, and your next handhold... is there. you don't have to go it alone. e*trade gives you the support and guidance to make informed decisions. are you type e*?

i have a cold. i took nyquil but i'm still stuffed up. nyquil cold and flu liquid gels don't unstuff your nose. really? alka-seltzer plus night rushes relief to eight symptoms of a full blown cold including your stuffy nose. (breath of relief) oh, what a relief it is. thanks. anytime.

there's some good news for diabetics. researchers at harvard coming up with a powerful weapon in the fight against type 1 diabetes. they say it is a breakthrough new treatment that could end up and replace all those insulin injections or pumps. doctor, this is really a relief especially if you've got to use insulin every single day. >> if it pans out the way we foresee it, this really has potential to be a huge breakthrough. we are talking about type 1 diabetes which is auto immune disease. type 2 diabetes which we see in industrial countries consists of 90%. this is a about 10%. it is a juvenile diabetes where pancreas doesn't make those beta cells, increasing cells. this is published in the "journal of cell." harvard researchers have used a stem cell to develop billions of these insulin secreting cells. they use them in mice to see if it really works and it has

actually done a great job. six months after the shoot something completely under control and they have a positive result. now they have to protect those because how do you protect these cells from immune system? that's what they're working on. this is coming to human clinical trial over the next few years. but i think in this pans out, no more insulin shots and we will be able to put in almost a pseudo pancreas for you. >> how -- type 2 more people have? >> type 2 is where most people are obese. they don't have enough insulin receptors. your engine, your pancreas is chugging along but not making enough insulin. type is where you have an immune reaction. your own body is destroying your o own pancreas that helps you get rid of your glucose. they've tried transplants.

eyelet cell transplants, the bo insulin. now finally in a laboratory they're making the cells themselves using stem cells. 150 million cells is what they need. they put them in mice and mice were controlling their glucose. >> if you have diabetes, how do you stop it or not get it? >> for type 1, you can't. it's really genetic. it's the antibodies attacking you. for type 2 you can prevent it by exercising and losing weight. >> everything we've spoken on "sunday house call" has always been about type 2 diabetes. everything. including reducing obesity which goes hand in hand with diabetes. diet. sleeping. antioxidants. that's helped out tremendously. that's type 2. this would be a revolution change when it comes to type 1 diabetes. i hope -- we have three to five years before we really see it in human clinical trials. >> it is an epidemic around the country. hopefully people exercise --

>> 3 million people. >> take care of ourselves. >> thank you, doctors, for a lively debate. we respect both of your opinions. that does it for us. join us every sunday, please. we begin with a fox news alert. brand-new video from the white house. these images on the left shot minutes ago showing president obama speaking with hhs secretary sylvia burwell updating the president on the newest ebola diagnosis in dallas. cdc's tom frieden spoke out this morning. >> at some point there was a breach in protocol and that breach in protocol resulted if this infection. >> top officials now dealing with what appears to be the first case of ebola contracted here in the u.s. i'm shannon bream here in washington. despite wearing full protective gear, we're being told a news who had
