there is a disease outbreak that is advancing in an exponential fashion.o be precise, that means it is doubling at a time interval and when you look at it as a graph, it is a picture of rapid upward acceleration. you heard from the general that most believe that the doubling speed is about every three weeks. this means that the outbreakers double. the response is increasing. not only are the governments themselves doing a great deal, but also many excellent intergovernmental and nongovernmental organizations are putting in additional resources. the increasing response is more like a linear speed. it would look like a straight line. what that means is that the outbreak is accelerating away from the control effort. and the longer it does that, the harder it is to get it under control and most importantly to enable the people of the affected countries for the prosperity and development that they have been enjoying so much in the last ten years. with an acceleration of the outbreak and the difficulty taxing, there is an increased likely hood of societal and ec

in west africa we are dealing with a situation where we are seeing an exponential case with 1500 plus deaths and the projections of going to 10,000 cases is not hyperbole because now the curve is exponential. the reason it is happening is because of the disparity in health care capability. that is the only reason it is happening because you cannot have infection control, no infrastructure for isolation. no infrastructure for quarantines and properly and no infrastructure for contact tracing. if there were the first two or three cases that were in the united states, it would be very frightening to everyone, all over the newspapers but it would stop. so i was adding prepared to get my three minutes of what i think the granite -- greatest challenge is is just that. there would not be be ebola academic if there were not absolutely does an -- stunning disparities upheld in the west african countries compared to our country. >> great. this is going to be a bit of a repetitive theme. there may be selection bias at work. let me first apologize for being late. it was something called ebola con

it was a growth, and it remains an exponential growth, for the reproduction rate of 1 to 2.o it is like this, it is still in that tomorrow, and so it has the possibility of migranting into ten or 12 of the neighbors or nearby states. many of which are quite vulnerable. so that is capturing people. i do not -- what sara was saying elier about the resolve of the commutes that are emerging. absolutely critical that that happened. i think it is also absolutely critical to emphasize when the defense minister, when brownie was here ten days ago, and in new york, it was a message of utter desperation. when the president sent the letter to president -- to our president obama, the letter was one of existential. it was we need to take extraordinary measures to rescue this situation from an existential threat. >> and that is something i will put you on pause, because we will get into that conversation right after the break, you just mentioned the spread to other countries the recent oxford study actually predicted it. say they ebola virus could hit 15 additional countries. coming up ne

yesterday cdc outlined in our report what would happen if the exponential growth were to continue at the rate it was going a few weeks ago. we do not think that will happen because of the response of the u.s. and others. but the worst-case scenario tops 1 million cases within a relatively short time, and not only would affect west africa, but would inevitably spread to other countries. we had two disease exportation events with the first couple thousand cases. how many events are we going to have if there are tens, or as the president said, potentially hundreds of thousands of cases? and whatever we may think, it is not possible to seal borders. it just does not happen in today's world. if it did, control of drugs and diamonds and people would be much easier, but it does not, and it is not going to here. and what that means is that we really are all connected. so while we do not think that if ebola continues to spread, as we believe it has been spreading all along, it will present a significant health risk to people in the u.s. it could absolutely change the way we work here and it c

--terday cdc outlined in our what would happen if the exponential growth were to continue at the rate it was going a few weeks ago. we do not think that will happen because of the response of the u.s. and others. but the worst-case scenario tops 1 million cases within a relatively short time, and not only would affect west africa, but would inevitably spread to other countries. disease exportation events with the first couple thousand cases. how many events are we going to have if there are tens, or as the president said, potentially hundreds of thousands of cases? think, it iswe may not possible to seal borders. it just does not happen in today's world. if it did, control of drugs and diamonds and people would be much easier, but it does not, and it is not going to here. and what that means is that we really are all connected. so while we do not think that if ebola continues to spread, as we believe it has been spreading all along, it will present a significant health risk to people in the u.s.. it could absolutely change the way we work here and it could change the economy of the wo

and that kind of thing is the example of what it is to have an exponentially increasing outbreak.t's doubling in 20-30 day ins the region. that facility had had 60 bodies removed that day. so the situation right now in west africa is an absolute crisis. it is moving faster than is easy to understand, particularly in liberia. we now have a field team looking at the possibility of cases in another country. if i were to just summarize for a minute, what we need is an immediate response that is sustained and then make sure that this doesn't happen again. and if i can just outline those three concepts for a moment, i've never seen a public health situation with this much need for immediacy. as i've explained to people, an adequate response today is much greater than a response in a week. that's the case in all three countries that are affected. even though liberia has, by far, the most out-of-control situation. but there are districts in liberia that are having relatively few cases. they have the opportunity to stop it before it spreads widely there. and where there are many cases, we'

we're truly watching exponential growth which is why we need to have an exponential acceleration in ourfforts to combat ebola, particularly in liberia and sierra leone and guinea. to build a little bit on what paul was saying, if we look at the historical and the contemporary examples, and with we see that that pace of ebola case growth doesn't have to be. i mean, uganda has had five ebola outbreaks in last 14 years, and none of which have become epidemic, because there is a strong the health care system in place. and there's a reason that there has been one isolated case in sen gal, and it is contained in the geographic area because of the robust health care system. our collective hope is this is a call to action not only to combat ebola but to help these countries build their health care systems to better prevent the next ebola case from becoming an epidemic and to better serve the needs of their populations more broadly. >> mr. ngafuan, please explain to us what is happening on the ground. you know, with the health care in the developing country, a poor country with a rudimentary hea

ebola is now an exponential crisis.ntain there is little risk of ebola spreading across the globe because ebola is not very easy to spread. the rapid acceleration of the virus in western africa can be understood by taking into extreme poverty and health care systems that plague africa. joining me is ceo of the global poverty project. so i want to start with you about the vaccine piece because i think americans have a sort of medicinal or pharmaceutical approach to thinking about public health. what is the vaccine possibly? is it on a timeline that makes sense given the exponential growth. >> we don't know how fast that will go up. we don't have good surveillance systems. for every case we know about there are more. how we bend the curve and get the data to understand what is happening on the ground is an important priority. we have invested more than $15 million in improving health systems in those countries but it obviously isn't enough to get the resilient health systems we want. traditionally we haven't thought about

it is a different strategy when you are on the exponential growth phase in an urban area. we need to look at this as a multifaceted epidemic and identify the major drivers and engage the understanding, public trust, community support to help break the chain of transmission. as many have said repeatedly, it is not that we do not know how to control a disease like ebola. we know how it spreads, and we know if you can reduce contact and you can use personal protective equipment and safe means of interacting with one another for those who care for sick patients, we know that war, and we need to engage it and engage community-level involvement in building that support. >> kevin, did you have one -- >> you were talking about the drivers, and you're absolutely right. one of the things we have not emphasized very much is the fact that one of the drivers is the population's response to ebola epidemic. the reason it is spreading in fact in some of these areas is because people who suspected they were infected fled the treatment centers and brought the infection elsewhere. and that w

there's an exponential rise in infections in the west african nation. free beds for ebola treatment have run out. that's forced untreated patients to return home where they infect others. a new area will be fully stocked and handed over to liberian authorities. you may wonder why this is so small. the facility is designed to treat health care workers who contract the disease. the brave men and women on the front lines of this battle. an american who contracted the disease is being flown to atlanta, bound for an isolation unit there. >>> and in a separate story, but also in the u.s., health officials are trying to determine if there's a link between hundreds of children in at least 12 states who've fallen ill with a res pir store virus. the symptoms start out like a cold, but many of the children end up critically ill, in hospital, and needing intensive care. anna cabrera has the latest. >> reporter: a child struggling to breathe. >> it's a parent's worst nightmare. >>. >> caller: this 9-year-old is hooked to oxygen tethered by tubes. >> she went from a

not linear, but exponential and how quickly can we get it done?lso, they have noticed that the u.s. government is not sending in doctors and nurses to directly take care of the general population of ebola patients, and that is what the world health organization says they need and that is what do doctors without borders says they need, doctor and nurse, and boots on the ground the take care of the general population of ebola patients, and there is a concern that is not what the u.s. government is doing. >> and why wouldn't the u.s. government want to do that? >> well, what they are doing is to send people in to train the health care workers, and i don't know why they have chosen not to do this, but an obvious sort of guess would be that they don't want people to get ebola. more than 250 health care wo workers have contracted ebola working in west africa and they don't want it to happen to the u.s. troops, but the administration has not been clear about why they chose not to go that route. >> all right. elizabeth cohen reporting live for us this mor

medical structure, and the cultural unfamiliarity of the virus lead to what was referred to as the exponentiald, and the outbreak is growing, so the public health containment measures, is going to be intended to bring that number down to less than 1, and i hear some optimism that the community there is beginning to accept that that's the behavioral issues about how you come in to close contact with persons who are infected or who have died of virus needs to be reversed. vaccines and therapies have an important role in all of this, especially in protecting medical workers and contacts of those who have been infected, but the main prevention, the way to bend that curve is going to be isolation and quarantine, and identification of cases. >> alan how much risk is there to the general population when infected individuals are brought into the u.s. for treatment? >> when the virus has not changed from the virus we have always known as ebola virus, the risk is just negligible. so close to zero -- because the person is brought in known to be infected, all protected measures are in place. everybody in
