>> rose: it's very scary. i know about ebola, and the only reason i do, it's because i've been just researching it on my own. since january, i kept hearing the word popping up in the news, and i just wanted to find out about it. >> richard townsend: when our supervisor said that we had a potential ebola case, i don't want to call it calamitous but there was a lot of concern. people became very vocal, understandably. it's the boogie man virus. >> pelley: emergency room nurses richard townsend and krista schaefer made sure that rose was suited up properly. as per the hospital's protocol, she worked with duncan alone, with townsend watching over her. when you went to approach mr. duncan for the first time, what did you do? how did you prepare for that? >> rose: i gathered myself together. i put on my protective wear, and i went in and introduced myself to him and, you know, just let him know that i would be the nurse helping him tonight. >> pelley: what were you telling yourself? >> rose: i was very frightened. i was. but and i just dried my tears, rolled down my sleeves, so to speak, and went on about my night. >> pelley: but why do you go in there? why don't you say, "you know, this one's not for me"? >> rose: as a nurse, i understand the risk that i take every day i come to work, and he's no different than any other patient that i've provided care for. so, i wasn't going to say, "no, i'm not going to care for him." >> pelley: but you were risking your life to take care of this patient. >> rose: oh, i know that. and that's why i... as frightened as i was, i didn't allow fear to paralyze me. i got myself together. i'd done what i needed to get myself prepared mentally, emotionally, and physically, and went in there and did what i was supposed to. >> pelley: though duncan's test results wouldn't be known for two days, she was certain she was witnessing ebola. >> rose: the first time when i went in and he vomited, i was standing in front of him, he was sitting on the commode, and there was just so much, it went over the bag, it was on the walls, on the floors. i had two pairs of gloves on and shoe covers. and i had my face shield on. i didn't have two masks on at the time, i had just one. no, we didn't have any head covers. but i wiped down the walls, wiped down the floor with some bleach wipes. >> townsend: he was having so much diarrhea and vomiting that he... you know, she was constantly having to give him the little bags that we have for... for people to vomit into. all of that was hazardous waste, and it had to be bagged and then double-bagged, and then put into a separate container that could then be disposed of later. because anything that has any of his bodily fluids on it has the potential to... to be lethal to somebody else. >> pelley: eric duncan was 42 years old, from liberia, which is ground zero for this outbreak. half of all the cases in the world are in liberia. he flew to dallas to visit family, became sick a few days later, and then made his first visit to the dallas hospital. it was the night of september 25 when duncan first came into this emergency room. according to the hospital records, he had a temperature of 100.1. over the course of the four hours or so that he was here, his temperature spiked to 103, but then it dropped back down-- again, according to the hospital records. he told the staff that he had come from africa, but did not specify west africa or liberia. about 3:00 in the morning, with his symptoms not very severe, the staff decided to send him home with antibiotics. but three days later, he was back in the e.r., gravely ill and about as contagious as he would ever be. the virus is not transmitted though the air, but physical contact with a single viral particle can cause infection. the hospital notified state health authorities immediately, and they wanted sidia rose to ask several urgent questions of duncan. >> rose: i explained to him, "we are under the impression that you may have been exposed to ebola. and i said, "where are you from?" and he told me liberia. and i asked, "have you been in contact with anyone who's been sick?" >> pelley: he said? >> rose: no. he said no. >> pelley: state and federal health officials wanted to know if duncan had been with anyone who had died in liberia. >> rose: and that's when he said to me his family had suffered a loss, that he had buried his daughter who had died in childbirth. >> pelley: but nurse rose says duncan told her it wasn't ebola that killed his daughter. rose told us that she reported this to the texas department of health, but then duncan denied his own story when he spoke to those officials. what information was it that he denied to the health officials? >> rose: about his travels, about his... him burying his pregnant daughter who had died in childbirth. he denied that. he said that's not true. >> pelley: so he wasn't honest with them. >> rose: yeah. >> pelley: this is nurse richard townsend, who dressed in the protective gear that was recommended by the c.d.c. at the time, just as sidia rose did. was any of your skin exposed? >> rose: at that time, it was just a gown that i was wearing, so yeah-- not my hands, not my legs, my face. i had my face shield on, the mask with the face shield. >> pelley: so your neck was exposed? >> rose: yes. >> pelley: so the c.d.c. protocols that you would've looked up the day he came into the emergency department were, in your estimation, deficient? >> yes. >> pelley: on september 29, duncan was carried from the emergency department to intensive care. nurse nina pham, who was involved in the transfer, would become the first person to catch the virus in the united states. it took 48 hours to get duncan's positive test results. and by then, the hospital, on its own, had equipped the staff with suits that allowed no skin to be exposed. it would be another three weeks before the c.d.c. made this its new standard. then, the hospital moved out all of the patients in medical intensive care and reconfigured the 24-bed unit for just one patient. it was a strange scene for icu nurse john mulligan. >> john mulligan: by the time i came in, they had already received the tyveks, the papers, so we had the full hazmat gear that people are used to seeing. >> pelley: is this the full suit? >> mulligan: this is the full suit, yes. there were always two of us in the room at all times, and we were designated two people to be in there. i've been in health care for nearly 20 years, and i've never emptied as much trash as just from the waste of his constant diarrhea that he was having was remarkable. and we had these longer surgical type gloves on. they were taped to the tyvek suit, full headgear with a circulator with a hepa filter that would plug into the back. and the first time i got out of that suit, it literally looked like someone had pushed me into a swimming pool. i was drenched. >> pelley: they were working 16- to 18-hour days, spending two hours at a time in duncan's room. >> mulligan: and we held his hand and talked to him and comforted him, because his family couldn't be there. >> pelley: you held his hand through the spacesuit? >> mulligan: i did. he was glad someone wasn't afraid to take care of him, and we weren't. >> townsend: i have nothing but respect and admiration for everyone that was involved in his... in his care, you know. everyone has someone in their lives that they love and they care about. i have a five-year-old and a three-year-old, and my wife is pregnant. and the mortality rate for pregnant women with ebola is... it's essentially 100%. >> pelley: but richard, why don't you go to the administration and say, "you know, i'm sorry, but my wife is pregnant." >> townsend: people were allowed to request not to be tasked with his care. >> krista schaefer: we asked for volunteers. everyone volunteered. >> pelley: everyone was a volunteer, everyone that was there wanted to be there? >> schaefer: every person-- housekeeping, respiratory, physicians, nurses. >> pelley: but despite all the volunteers, duncan grew worse. an experimental drug wasn't helping. >> mulligan: early saturday morning, he had become very critically ill and was placed on a respirator. >> pelley: he was intubated... >> mulligan: he was intubated. >> pelley: ...tube down his throat? >> mulligan: tube down his throat. he had a dialysis catheter placed, because his... he was not making any urine, but he needed to. he was heavily sedated and he had tears running down his eyes, rolling down his face, not just normal watering from a sedated person. they... this was in the form of tears. and i grabbed a tissue and i wiped his eyes and i said, "you're going to be okay. you just get the rest that you need. let us do the rest for you." and it wasn't 15 minutes later, i couldn't find a pulse. and i lost him. and it was the worst day of my life. this man that we cared for, that fought just as hard with us, lost his fight. and his family couldn't be there. and we were the last three people to see him alive. and i was the last one to leave the room. and i held him in my arms. he was alone. >> pelley: sidia, you spent perhaps the most time talking with mr. duncan, and i wonder what you think people should know about him. >> rose: he was very kind and very appreciative. even something as simple as me just giving him a cold washcloth to cool his face down, because his fever wasn't breaking-- even that he was grateful for. he told me thanks. >> pelley: within days of duncan's death, nurse nina pham was admitted to the hospital with ebola. when nina became sick, that must've sent a lightning bolt through the staff because, now, it's one of you. >> mulligan: i thought someone was playing a cruel joke until i finally looked at my phone, and saw the missed text messages and the voicemails and turned the news on and went, "oh my goodness." >> pelley: then four days later, nurse amber vinson fell ill. both nurses have since recovered. this is nina pham leaving a hospital on friday. but many on the staff still wonder whether they could be next. are any of you, all of you, still self-monitoring for signs of infection? >> rose: i am. >> pelley: you are? you're still within the 21-day window? >> rose: for mr. duncan, i'm passed my 21-day period. but for nina pham, i'm still being monitored. i've been asymptomatic. my temperature has been rock solid. >> pelley: those who contract the virus are not infectious until they actually become sick. members of the medical staff must take their temperature now twice a day and show the reading to a state health official. but, in at least one other way, the effect of fighting this virus could linger. >> mulligan: i would have nightmares, and still do, of my co-workers being infected and not being able to get to a hospital and treatment and dying. and so its like any traumatic event-- this too shall pass; it's just going to take a little time. >> subs must be wach update sponsored by: >> good evening, 13 euro zone banks have failed their latest stress test. parties favoring closer economic ties to the west have claimed victory in ukraine's election. and 772 americans gave up their citizenship last quarter to avoid tougher international tax rules. i'm jeff glor, cbs news.

>> mark hughes: no, but that's the fun of science, it's constantly surprising you. wow, look at that! >> o'donnell: dr. mark hughes is one of the scientists leading the way in a rapidly growing field known as reproductive genetics. he pioneered a technique called pre-implantation genetic diagnosis, or p.g.d... >> hughes: this one's got a minus-two. >> o'donnell: ...an embryo screening procedure that can identify deadly gene mutations and alter a child's genetic destiny. >> hughes: we all throw genetic dice when we have children, but when you know the dice are loaded and that there's a really reasonable chance that your baby will have an incurable, dreadful condition, you're looking for an alternative. >> o'donnell: dr. hughes helped develop p.g.d. two decades ago to screen embryos for one disease, cystic fibrosis. today, because of advances in the mapping of the human genome, he says it can be used to root out virtually any disease caused by a single defective gene. let me do a rapid fire yes or no. can you use p.g.d. for tay- sachs? >> hughes: yes. o'donnell: muscular dystrophy? >> hughes: yes. o'donnell: sickle cell anemia? >> hughes: yes. o'donnell: hemophilia? >> hughes: yes. o'donnell: huntington's disease? >> hughes: it's one of the most common disorders we test for, yes. o'donnell: alzheimer's disease? >> hughes: if it's a mutation in a particular gene that causes early onset, we can test for it, yes. >> o'donnell: so you can test for alzheimer's. >> hughes: this is a small subset of a particular kind of alzheimer's that attacks very early in life. o'donnell: colon cancer? >> hughes: if we know which of the colon cancer genes, yes. o'donnell: breast cancer? >> hughes: we do it regularly. >> o'donnell: dr. hughes' lab is one of a handful in the country that provides this genetic testing, which is why 3,000 couples turn to him each year, among them, matt and melinda, who asked that we not use their last name. if they hadn't done the embryo screening procedure, their four- year-old son mason and his baby sister marian might very well have been born with a genetic mutation that increases the risk of breast, ovarian, prostate, and pancreatic cancer. it wasn't until melinda herself was diagnosed with an aggressive form of breast cancer seven years ago that she found out she carried that gene mutation known as brca1. did you know what brca1 was? >> melinda: not a clue. >> o'donnell: but as it turned out, it had haunted her family for generations. at age 29, facing chemotherapy and a double mastectomy, melinda was afraid that if she had children one day, they would also be cursed with that potentially deadly mutation. what did doctors tell you about the risk of passing on this brca mutation? >> melinda: 50%, so flip a coin. >> o'donnell: and i bet that weighed on you even heavier. >> melinda: yes. it's a lifetime of having to worry about it, and i just didn't... i didn't want my kids to have to do that. >> o'donnell: the best way to ensure that was to do embryo screening for the brca1 gene mutation, which dr. hughes says is among the fastest-growing parts of his business. >> hughes: this takes the risk... for example, in breast cancer, it takes the risk if you have this mutation from 50/50 of passing it to the next generation down to less than 1%. >> o'donnell: but the screening isn't easy. all couples, even fertile ones, must first go through in-vitro fertilization, the process in which a man's sperm is injected into a woman's eggs under a microscope to create embryos. then, five days later, a tiny tube just one 20th the diameter of a human hair is used to extract from each embryo one single cell to be genetically tested for disease. it's just one cell? >> hughes: yes. >> o'donnell: you can tell that much from one cell? >> hughes: you can tell an awful lot in one cell. >> o'donnell: that cell is packed up at fertility clinics across the country and shipped overnight in ordinary-looking boxes like these to screening labs. we followed the process at dr. hughes' lab, called genesis genetics, just outside detroit, where a team of scientists took over. so what do you do with that one cell when it arrives here? >> hughes: well, we're busy. we have to break the cell open. they have to pull out this enormous encyclopedia of genetic information. >> o'donnell: he's talking about the cell's dna, our genetic code that scientists represent with four letters-- a, c, t and g. for a gene to work properly, the letters have to be strung together in the right order. if they're not, that could spell trouble. it's dr. hughes job to find the mutation, or "typo," in a gene that could cause disease. >> hughes: so you have to find that typo in, effectively, six billion letters. >> o'donnell: a typo in six billion letters? >> hughes: yeah. >> o'donnell: so how do you do that? >> hughes: technology is amazing. >> o'donnell: dr. hughes used the technology to screen matt and melinda's embryos in 2010, ruling out the ones that carried the brca1 mutation, which would have given their children a reasonable chance of getting breast or other cancers. about how many of them tested positive for the brca1 gene? >> hughes: about half and, indeed, if you look at her embryos, here is an affected, an affected, an affected, an affected-- that's four. it's about half. it is just what you'd expect. it's just what you'd expect in nature. >> o'donnell: but with the powerful intervention of science, embryos that carry a harmful mutation are often discarded, which is one reason the decision to go ahead with the screening was a difficult one for matt and melinda. >> melinda: we prayed a lot about it. it's a hard decision to make. >> o'donnell: what did you struggle with? >> melinda: was it right? was it the right thing to do? is that... is it playing god? is it ethical? and the more we learned about it and got comfortable with the idea, it was like, "yes, absolutely." >> o'donnell: you have said, "the breast cancerstops with me"? >> melinda: yes. it's not just my children-- it's their children and my grandchildren and great grandchildren, forever and for all time, in my bloodline, yeah. >> o'donnell: the entire process cost them around $16,000, a small price to pay, melinda says, for her children's health. >> anne morriss: oh, let's try that one again. >> o'donnell: but anne morriss didn't get to change the odds for her child. by the time she learned she carried a dangerous mutation, she had already passed it on to her son, who's now seven. at birth, alec seemed the picture of health, but then came an unexpected call from a doctor. >> morriss: he started by saying, "can you please go check and make sure that your child is still alive, and then come back and we can continue this discussion." >> o'donnell: so a doctor calls you and says, "i need to tell you something but can you go check that your son is still alive." >> morriss: that's how the conversation started. >> o'donnell: what was your reaction? >> morriss: you know, your... your heart just falls out of you. >> o'donnell: a newborn screening test revealed alec had a rare and sometimes fatal metabolic disorder called m-cad deficiency. he had to be fed every few hours just to stay alive. >> morriss: let's see what you got, buddy. >> o'donnell: unlike breast cancer, m-cad deficiency is a recessive disorder, meaning a child must inherit a copy of the faulty gene from both parents. anne morriss had used an anonymous sperm donor to conceive, but in an incredible case of bad luck, he just happened to carry the same mutation she did. >> morriss: every human being walking the planet is a carrier for a rare disease. but what matters is who we choose to partner with reproductively. like, that's where the risk shows up. >> o'donnell: now, she wants to reduce the risk of a bad genetic match for others well before they start the reproductive process. she just started a company called genepeeks with lee silver, a princeton university professor who's also a molecular biologist, though his latest idea doesn't take place in a lab. it's entirely virtual. >> lee silver: we are creating digital babies. >> o'donnell: digital babies? >> silver: yes. >> o'donnell: so you're simulating the process of reproduction, but on a computer. >> silver: exactly. >> o'donnell: silver says all it takes is a saliva sample to obtain dna. he then combines the genetic information from both prospective parents in a computer to make a thousand digital babies. this is a digital baby. >> silver: this is a digital baby. >> o'donnell: it contains virtual dna, which, like real dna, is represented by those same four letters-- a, c, t and g. >> silver: this baby has a mutation. >> o'donnell: he says that by analyzing the dna in all those digital babies, he is able to calculate the risk of two people conceiving a child with any one of 500 severe recessive pediatric disorders. now, genepeeks is available for $2,000 to clients using sperm banks and egg donors to conceive, though its founders say the goal is to expand it to all couples who want to have a baby. you think everyone who's going to have a baby should go and have a digital baby first? >> silver: i see a future in which people will not use sex to reproduce. that's a very dangerous thing to do. >> o'donnell: that may sound far-fetched, but the way lee silver sees it, there will come a time when couples will no longer want to conceive naturally because it's too risky. >> silver: it's safer to have a baby with this pre-knowledge, this genetic information that might help them avoid disease. but with the promise of this technology also comes the fear that some parents would want to use it to select genetic traits in their children that have nothing to do with disease, a debate lee silver himself stoked when he wrote the patent for genepeeks. we read your patent and it says your technology could be used to assess whether a child could have other traits like eye color hair color, social intelligence, even whether a child will have a widow's peak? if your company is so focused on preventing disease, why would you include those traits? >> silver: the purpose of the list of traits is simply to demonstrate that our technology can be used to study anything that's genetically influenced. that doesn't mean we're going to actually do that. >> o'donnell: okay, but you're running a company? that could be big business? >> silver: we are the... the ones who invented this technology, and we're going to use it to study pediatric disease. at the moment, we will... we will make sure the technology is used only for that purpose. >> o'donnell: and at the moment, you'll have to take his word for it because there are no real rules in this country limiting what this kind of technology can be used to screen for, leaving those decisions up to scientists like lee silver and mark hughes. so, we should trust you to set the boundaries? >> hughes: if i'm setting a boundary, saying, "i'm not willing to do that," that's no different from any other field of medicine, so sure. >> o'donnell: but do you wrestle with this, at all? i mean, who is the gatekeeper? >> hughes: that's the question. should it be some group sitting around a mahogany table, or should it be all left up to the patient. if it would get to the point where it was like cosmetic surgery, that would be downright awful. but i'd think those are all straw men arguments, and people asked me these very questions that you're asking me right now, 25 years ago. and it hasn't happened. that's in part because researchers still only fully understand traits and diseases caused by a single flawed gene. there's a lot left to learn about the interaction of multiple genes. but when that happens, mark hughes and lee silver believe their technologies will be able to screen for a host of genetically complex dseases that they say could include schizophrenia, and some types of diabetes and heart disease. >> silver: i think it's going to be used by society in the 21st century, just like we used antibiotics and other advances in the 20th century to drastically reduce the risk of infectious disease. we're going to be able to drastically reduce the risk of genetic disease. >> o'donnell: you're comparing this ability with reproductive genetics to antibiotics and vaccinations? >> silver: i am. and in some ways, this is more powerful. >> o'donnell: earlier this month, because of how quickly the industry is growing, the fda proposed guidelines to review certain genetic testing to ensure the technology used in the diagnosis of serious diseases is accurate and safe. >> welcome to the cbs sports update presented by pacific life. i'm james brown with scores from around the n.f.l. detroit scores 22 unanswered to beat atlanta in london. seattle snaps a two-game skid with a late come yam win over atlanta. cincy regains the top spot in the a.f.c. north. big ben's team record six touches sinks indy. the bills score six turnovers to ground the jets. tom brady throws for five touchdowns in the pats' win. for more sports news and information, go to cbssports.com. it on the long journey to their feeding grounds. one of the most important things you can do is help the next generation. at pacific life, we offer financial solutions to accomplish just that. ask a financial advisor about pacific life. the power to help you succeed. campbell's® fiesta chicken sausage and pepper rigatoni. southwest style bean & barley. tuscany style chicken and pasta. if you think campbell's® 33 new soups sound good... imagine how they taste! m'm m'm good!® [cat thinking] yyou smell... nothing.
