So this second American as I understand it is common in. Set to return tomorrow with the Ebola Virus and I just thought with all of the talk of it I think a lot of us know of it we don't know about it so. We invited Steve Morse on his -- professor doctor Steve Morse professor of epidemiology. Columbia. Global co director -- predict. You said emerging pandemic threats program -- Columbia university and institutional bio safety committee and doctor I think -- should tell you at this point I'm nowhere nears intelligent issue. And are not so so you might want to in my -- ago it was slow. Let's talk about the -- where does this come from and I think people have gotten texts that are confusing it with E. Coli. And maybe it well now on just on his so maybe you can explain give us the good 101 course owners. -- sure absolutely well Ebola is the buyer. Eco light courts that are famous bacteria. That have a lot of Scotland. Very common cause of gastrointestinal. Problems. But and some other things that Ebola is higher. Mr. discovered by western -- at least in 1970. And I'm sure they were cases that we know about it and it'd -- stronger parts of Africa. But there were two outbreaks and Obama the same time in 1976. In look whose ankles -- ear now of the Democratic Republic of the Congo. And Sudan. And -- there are about 200. -- cases in each of those outbreaks and of course at that it's very scary and during this year is neat because nobody knew. How people caught -- and also belong to such a rather unusual -- water. So. Called the killer virus has become a thing they have kind of the -- like appearance. On the scene. Pictures -- them under its. Very high magnification. Thing that you can look like. But of course they're they're very gently. Band since then there has been that bad debt so -- well outbreaks in various places. Put the first time we've seen it in West Africa. That is the virus has probably been there for some time there have been occasional case that escaped people's notice because they didn't get quite. Far out of control. Ebola causes so we color hemorrhagic fever. That means that that people come -- interest for the -- candidate. I think you really stick it so it sort of like -- buried Lou but then they get much worse. With -- -- units of blood vessels often bloody diarrhea and so on being here. And occasionally in a little less than half the patient Q do you see that the same. Bleeding from your source -- -- than and so on that is that same. In the media movies that the student be most of the time. Either you don't see anything quite so obvious but there's a lot of internal. Blah blah and eventually. The patient will go into shock it's not properly. Treated. And unfortunately. It is fatal. It's -- entry in about 90%. With this particular. Art that -- scared. And understandably people were scared when. Pacers came to investigate it now and it's very Arctic catchy little -- -- and spread like. The flu or something like that it it really requires very close contact. -- is. The infected bodily fluids or tissues. Of patients with the ball so it's really out here work here. And family members who are taking care of these victims who. Really are in line -- higher and in danger catching the disease and that's how. It's been happening in the outbreak. So the you know I don't guess all of taxer and pardon me but the people -- have contracted this in West Africa. That's because the methods are you so much different than they are here in the United States. It's spread a lot easier alluded to explain it to me -- Well initially. Actually mr. To outbreak especially in Sudan. The many -- week. Where in fact people who were in the hospital the same time it's something else that. This is such resource limited play you know they just didn't have much. In the way it supplies that that particular. Hospital at least it's and so at needles and syringes. Show. You know they had to re use them over and over again without having to sterilize them. And that someone wondered -- people came in with Ebola. Today. Injected. Period perhaps you know medications. To blood samples. And they rent them. These syringes. And use them. The regular patients and many am contracted at -- as you'd expect would say HR in your appetite. -- The importance of infection control -- -- really -- measures to separate people patients. -- There. The people in the hospital to make sure that. You used there are men and that you properly dispose. Properly dispose. The waste. -- -- -- -- -- -- That that people who -- taking care of the sanctions. Really answer. In the right precautions for infection control that means wearing. Written a protective equipment that your doctor or near the -- Making sure that she only masks gloves and another thing. That prevent you from accidentally. Getting this done and I think yours and your five. And basically you know that's really the major thing that needs to -- It in the country we have. Infection control procedures. That are followed rigorous and that the patient -- -- It can be done. But obviously. People. Are not used to use such high consequent. If you make. And some people are very tired where they're not highly trained in -- I think they accidentally. Infect themselves when they're taking their protective gear or accidentally it. Themselves that needle taking blood active or something like. We're almost out of time donation is collection in terms of common. Did traveled Manson's airlines center of somebody hands as they don't know it incubation periods how long can it live on a surface and if if they have it and they touch headphones whenever airlines Seton and -- touch that. Can you contracted knowing concerning live for a long time it at room temperatures. -- the the greater risk is is probably you know the fact that they're. That person the sick with the ball and until later critics they're not going to. Be danger infectious to others. The bloody diarrhea or vomiting you know. Are obviously. A possible source citizens action. We did jets have double the patient who died after he landed on applying and I think it will be -- interest. Just fine. You know what happened to the other people on the plane I'd be surprised it's it's sending them that they -- credible themselves. Get had gotten infected the groups and you know know more about that incubation period is anywhere from 221 days. So you really do have to watch for awhile and you and they -- Take people's temperature and if you have a high temperatures they keep keeping an isolation. Thank you doctor which -- have more time we got to go the doctor Stephen Moore is professor of epidemiology Columbia local global gold director. Predict. The pandemic threats program.
