University hospital, says it is preparing to receive a patient with the ebola virus airlifted to this country from africa while in isolation. This outbreak is now surging out of control. New numbers out today show over 1,300 cases, 729 deaths reported. In this country the cdc has issued what they call a level 3 travel warning, thats their highest level. So far it concerns those americans headed to the infection region in western africa. This while u. S. Hospitals have been put on notice, all of them, to be alert for patients who may have the symptoms after returning from that part of the world especially. Its where we begin again tonight here with our chief medical correspondent dr. Nancy snyderman. Nancy, good evening. Good evening, brian. The news today from Emory University hospital saying that it is preparing a special Isolation Unit to receive a patient with ebola within the next few days. Which patient will be treated . We are not sure. But in the meantime, two american lives are hanging in the balance. The relief agency, samaritans purse, said today the conditions of two of their american volunteers in liberia, dr. Kent brantly and Nancy Writebol are deteriorating. Yesterday an experimental serum arrived in liberia but only one dose. Dr. Brantly heard that, he asked that it would be given to nancy and not to be given to him. Reporter Franklin Graham is head of the relief organization. Hes a tremendous individual. Reporter however, dr. Brantly did get some help, a blood transfusion from a 14yearold ebola survivor, one of the many people dr. Brantly has saved. This is the toughest Ebola Outbreak weve ever had to face, and ebola itself is a dreadful and merciless virus. Reporter and to date the centers for Disease Control issued a level 3 travel alert for americans urging them to avoid all nonessential travel to guinea, sierra leone and liberia. So what was your Tipping Point to raise the travel advisory today . We were concerned that if you traveled there for a nonessential reason and had to go to the hospital, that might be a problem. Reporter in brooklyn park, minnesota, home to americas largest liberian community, officials are discussing added precautions because so many residents travel back and forth. Our community has a significant amount of concern and, quite frankly, fear over whats going on and the likelihood or possibility that the virus could be introduced into our community. Reporter the situation is so dire in western africa, the peace corps is bringing home 340 volunteers. Sharayan yun left guinea last week. Your first reaction is sort of to freak out, to be afraid. Weve all heard about ebola. We all know its a horrible way to die. I dont have to tell you that americans are worried. We should be able to be very rational about this. You cant catch ebola from someone who is not sick and very sick with it, and you cant catch it by casual contact. It requires really intense contact where theres exposure to body fluids. In the meantime, the World Health Organization has announced a 100 million response plan, and tonight there is a global call for doctors, nurses and epidemiologists to bring your expertise and supplies into the affected areas in western africa, brian. And the feds still believe well be able to avoid this process of taking people off planes who may be sick, checking people at our incoming airports . People are infectious if they are symptomatic. If you look at this outbreak right now in western africa think of it like a wildfire that is raging out of control. If there are isolated sparks of affected patients, those patients need to be isolated. Thats how you ultimately shut this down, but its going to be months, not weeks. And in the meantime, the patient thats coming to the United States is going to get the expertise and very sophisticated medical system and will not be putting other people at risk. All right. What a scary illness, however. Dr. Nancy snyderman starting us off. Thank you, as always. Overseas tonight, some hopeful news just late tonight between israel and hamas. Secretary of state john kerry traveling in indiana announced a 72hour ceasefire to begin friday morning and he said israeli and palestinian negotiators will head immediately to cairo for further talks. One thing that hasnt changed in this, earlier today, the israeli prime, minister benjamin netanyahu, vowed to destroy the network of tunnels that hamas uses to terrorize israel, something he said would be done with or without a ceasefire. Israelis living near the gaza border live in constant fear of tunnel attacks from beneath their homes and towns and farms. Our veteran middle east correspondent Martin Fletcher tonight gets a rare firsthand look.

Here, three days ago they surprised soldiers at an army post and killed five, dug through clay and sand, the tunnels are hard to find. 45 feet deep down here. Concrete arches, electricity, telephones, almost six feet high, more than two feet wide. Hamas has built dozens of them. The army wants time to destroy them all. 32 found so far. So this tunnel in this direction goes one mile, more than a mile into gaza. To the town of ha. Yunis. In this direction only a few more hundred yards israel, it comes up inside an israeli kibbutz in the farming land. Israel was this close to another tragedy. I feel sick really like wanting to throw up from anxiety. Reporter this woman lives a mile from gaza. People say okay we kcan live with the shelling but not with the threat of tunnels. [ speaking a Foreign Language ] reporter her friend came back last night after three weeks in the north sheltering from the rockets, terrified of the tunnels, but her kids missed home. Exciting with lots of fear. You know, its not easy. Reporter this morning trying to make it easy for the kids who stayed, but theres always fear of rockets. And now the tunnels, will hamas fighters suddenly pop out of the ground . And the boom of israeli guns firing into gaza. So people ask me how you raise your children here in that place. So i tell them, its my house. Oh, my god. Oh, see. To come back to this, i dont like. This is ah but we get used to it. Reporter but the guns may fall silent in the morning. Hamas spokespeople say that hamas has accepted the latest ceasefire proposal to last 72 hours from tomorrow 8 00 a. M. Local time and it appears that israel has accepted too. So the two sides should meet in cairo tomorrow. Brian. What an incredible scene during that interview. Martin fletcher from tel aviv for us tonight. Martin, thanks. Tonight, at least one u. S.
