We start with the nurse in australia who is now in medical isolation amid fears she too could have ebola. Officials say the 57yearold woman from the city of cairns returned last weekend from treating ebola patients in sierra leone. Now she became concerned after developing whats described as a low grade fever when she returned. She went to an area hospital, test results are expected back friday morning. I just spoke with a reporter there who describes her condition as stable. Officials right now are trying to keep the public calm as well. See came back into the country. Did not have a fever so its only since this morning shes had a low grade fever. She has not been out in the community in cairns. Shes been at home isolated in her own home testing herself. Well keep an eye on that situation. But the first person diagnosed with ebola in the United States has died. Thomas eric duncan got sick last month after arriving from liberia. Meanwhile, a texas Health Official says there is no risk of ebola for a sheriffs deputy hospitalized wednesday. The deputy had responded to the apartment where duncan was staying but says he had no direct contact with duncan. And meantime, thomas duncans partner wants an investigation now into how his care was handled before and after his diagnosis. Yeah, David Mattingly looks at how duncans case differs dramatically from other ebola patients sent to the United States for treatment. Reporter Thomas Eric Duncans death leaves behind a trail of questions about ebola treatment and prevention that is more than 5,000 miles long. Liberian Health Officials didnt expect the sick woman he assisted was infected with ebola until after duncan was already in the United States. Five days after his arrival, an ailing duncan goes to the hospital in dallas and tells them of his recent travel from africa. But they just give him antibiotics and send him home. Regretfully that information was not fully communicated throughout the full team. And as a result, the full import of that information wasnt factored into the clinical decisionmaking. Reporter duncan spends three days potentially exposing others before hes back even sicker this time in the hospital. It takes two days to confer. Hes infected with ebola. Duncans case is a sharp contrast to doctor kent brantly and missionary nancy writebol. Both were diagnosed in africa and given an experimental drug zmapp and flown to the United States and quarantined. The drug seemed to work. What a great, great nursing staff and what great doctors. You treated me with expertise, yet with such tenderness and compassion. Reporter duncan was in the hospital for nine days when his girlfriend speaks from quarantine begging he get the same experimental drug. Im just asking god and asking the American Government the same medicine they gave to the people that came from liberia, the ebola people that came, the people with ebola that came please help save his life hes too young to die. Reporter but supplies are depleted. He was given a different e. Peerptal drug already in serious condition. His status doesnt improve. Blood transfusions from ebola survivors are also believed to provide antibiotics to patients still fighting the disease. Dr. Kent brantly today gave blood to one ebola patient, an nbc cameraman. He also gave blood to an infected doctor who has since recovered. Both writebol and brantly agreed to give blood to duncan but only works in their blood types match. Now it no longer matters. Today we are deeply saddened by the death of the patient in dallas. Reporter duncans case ends with the worst possible outcome. Brantly was out of the hospital in 19 days, writebol out in 14. After finally being admitted, Thomas Eric Duncan died in 11. David mattingly, cnn, atlanta. Well, meanwhile, there is a lot of anger, and anxiety in spain. Thats where a nurses assistant has contracted ebola and five others are under hospital observation to see if they have the deadly virus, as well. So lets go live now to madrid where our al goodman has the very latest and, al, what new information we learning on how this nurses assistant contracted the ebola virus and whats been learned from this as medical facilities across the globe struggle with just how to cope with the threat of ebola . Reporter hi, rosemary, well, all of these people that you mentioned are in this hospital, now the nurses assistant Teresa Romero apparently maybe according to a doctor who has talked with her who came out and spoke with the media yesterday right here said that she says that when she was taking off her protective suit and gloves, remember she was part of the medical team that was treating two other ebola patients, spanish missionaries who got it in africa, came back here, both of them died. That when she was taking off her protective gear after treating one of them, that she may have touched her face either with a glove or some or party of the gear. Her exposed face so thats what theyre Say Something a potential cause of this but in the broader sense, theyre talking about the protocols. Now, the official line when this story broke was all the procedures and protocols were correctly followed, so says the government but at a meeting in with the European Union officials from the 28 European Countries talking about what to do with this crisis yesterday in brussels, the note that came out of that says that spain says it doesnt know exactly how it happened but possibly there was some protocols that were relaxed in handling the corpse of one of the ebola patients that died or in handling the disposal of the medical waste. So there are beginning to be the first sort of admissions possibly that it wasnt just the nurses assistant, rosemary, that there may have been a procedural error or maybe they werent in place in the first place. Yeah, cant be too careful in these instances, clearly. And, al, the fallout from the euthanizing of this womans dog, we saw the pictures of her with her dog. That fallout has generated a lot of anger on the streets of spain. Talk to us about the effort to save at dogs life and why authorities decided that they had to do this . Reporter well, the authorities are trying to contain this serious issue, so in addition to the people who are in here, shes the only confirmed case, the five others under observation monitoring 50 other people. The husband of the nurses assistant from the hospital started a campaign a couple days ago to try to save their dog whose name was excaliber. And that built up a Huge Campaign and there were protests outside their home in a southern madrid suburb but the authorities said theyre going to go ahead and euthanize the dog. There were medical experts say it might be better to isolates dotting see what happens. Does the dog get ebola . Hasnt been a known case of that but out of extreme precaution theyll go ahead and euthanize the dog which happened yesterday. Other protests, as well, against the government by medical workers talking about lack of transparency alleging that the procedures and equipment was not adequate to confront this crisis, rosemary. All right. Al goodman hopefully lessons have been learned in this and they can be useful right across the globe at this stage. Al goodman reporting there live from madrid. Many thanks to you, errol. Rosemary, the fatality rate in west africa is so high because of a Health System thats been overwhelmed by this epidemic and some would argue wasnt even prepared for it before it began. Conditions are dire especially in liberia where patients often dont even have a bed. Nima elbagir takes us inside. Reporter blood spattered and limp, too weak to hold up his head. A nurse struggles under the weight of a desperately ill patient. The nurse agreeing to wear a camera to give us a glimpse of the bleak reality he witnesses daily. Here at this governmentrun Treatment Center today, the nurse managed to get this patient to drink water. Its a small victory. For the last two months, dr. Moses and his team have worn their protective suits in unbearable heat walking the high risk wards to tend to the patients in their care. Life is rough and then you die. What else can we do if we dont do it, who will do it for us . So we have to take the risk and care for the patients or else our country will be wiped away. Dont leave some behind. Bring the whole thing. Working in arisk zone is dangerous and you hvae so many patients in agony. Some patients are dying. Some patients need help. Some patients cannot move any longer and you see some patients you cannot do anything for them. They are guying dying and all you do is watch them die. Sometimes you pray for them and do the little, you do and just hope that something miraculous happens. Reporter dr. Moses got one days training before going into these wards and says thats typical here in a Health Care System struggling to cope. You do what you need here to survive. The nurse forgets the camera for a moment and begins to hum a hymm to himself. A comfort amidst the grimness. An ambulance has arrived bringing more patients. It begins again. There is no room so the stretcher goes on the floor for now. Next to a mattress where another critical patient lies. Here there are two patients for every bed. More patients. It is unimaginably unrelenting. But there are the success stories, and thats what sustains the staff. Around the back of the ebola ward patients spot the camera and begin to wave. Theyre recovering, maybe even going home soon. But for the staff, there is no end in sight. What happens when you go home at the end of the day . I get prepared for another day. Reporter and another day and another day until their prayers are finally answered. Nima al bagger, cnn, monrovia. Just extraordinary watching these nurses in action. The nurses and the doctors have just been extraordinary. That point of view, i mean this is what theyre experiencing each and every day and as we keep reporting these are the folks on the front Line Contracting the virus, they are literally putting their lives on the line to help so many others so well continue to track all developments as it relates to this ongoing epidemic. Yeah, of course, well have much more including a look at the new option being taken at some of the u. S. busiest airports to try to prevent the virus from spreading further. Also ahead. No, im not making it right now. Im scared for my life. Because he just pulled a gun on us. We dont have a gun. Some new accusations of Excessive Force against Police Officers in the u. S. Well show you what led up to this violent confrontation. The mother of an american man threatened about beheading is looking for news. Paula kassigs who son goes by the game abdulrahman appeared at a vij until indianapolis and sent a tweet meant for isis leader abu bakr al baghdadi. Now, abdulrahman is a u. S. Military veteran kidnapped last year while doing aid work in syria. Isis militants threatened to kill him in a video last friday. A Syrian Rights Group says isis now controls onethird of the Turkish Border town of kobani. That comes as the u. S. Military says it launched eight air strikes against isis targets near the town on wednesday. But the pentagon says air str e strikes alone will not save the town from falling to isis. Jim sciutto reports. Reporter a u. S. B1 bomber in disguise over kobani. The rescue that kurdish fighters batting isis there have been desperately hoping for. Military commanders say Coalition Air strikes have helped push isis back. Today pentagon spokesman admiral john kirby bluntly warned that the u. S. Led air campaign will not save kobani or for that matter any number of other syrian towns under isis assault. Are you preparing the public in effect for the fact that not just kobani but other syrian towns may fall over the long haul of this air campaign until you have those competent forces on the ground . I think we all should be stealing ourselves for that eventuality, yes. How do you deny isil the safe haven without taking back that territory . The longterm fix is and we recognize that is going to be competent Ground Forces that can retake territory from them. Weve been nothing if not brutally honest about the fact as to what military power can do here. Reporter without those competent Ground Forces the goal says u. S. Officials in unison is not taking back territory, but destroying isis command and control, heavy weapons and oil depots. Targets that secretary of state john kerry said take precedence over protecting a besieged population. Were trying to deprive isil of the overall ability to wage this, not just in kobani, but throughout syria and into iraq. Reporter in iraq where the u. S. Does has partners on the ground in the iraqi and Kurdish Security forces, u. S. Officials say that territory does matter and they claim victories in retaking the mosul dam, the haditha dam and protecting irbil and baghdad from further isis advances. Still, the map of isis controlled territory in iraq looks. The same today 61 days into the air campaign as it did before the bombing started. President obama came to the pentagon wednesday to meet with his commanders to discuss the strategy against isis. Its a rare visit and the last three years hes come here before for only a 9 11 commemoration ceremonies and for a personal health checkup.

Now the biggest storm of the year is aimed at the region. We turn to our meteorologist Pedram Javaheri who joins us now with more on that. Pedram. You know, this storm system, japan dealing with this in a similar way we saw across the philippines this time last year, a multitude of typhoons impact that region an now seems like the weather turn in the direction of japan in recent week answer this particular storm with those 207 kpr winds, it would be a category 5 equivalent with 50foot wave heights. A couple good thing happens, weakening taking place and another thing you cant see cooler water temperatures ahead of the storm system so you put it together you expect the storm system to weaken inside the next three days before it makes landfall across mainland areas of japan but okinawa and all 1. 4 Million People across the island going to be in the direct path of what still could be a super typhoon on friday night into saturday morning when the storm system makes landfall and that region, again, about 50,000, about half of the 50,000 u. S. Troops stationed in japan are stationed in okinawa. Three u. S. Airmen lost their days with the typhoon that made landfall. This is going to take a similar track and eventually as we head on into sunday and monday, around portions of kyushu prefecture with the storm weakening from the 230 kph to 160, category 1 once it makes landfall. But got to share this with you, hazardous air quality across beijing, just a few hours ago, being shared with us of whats happening across beijing. Take a look at this. The air quality index up to 400 which is nine times higher than what the w. H. O. Would consider healthy breathing air. Curious watching us from the western end of the United States, of course, los angeles has a dubious distinction of the dirtiest air in the United States but on their dirtiest days they get down to about, say, 80, 90 on that scale so typically it would be moderate on the scale. A very routine pattern for beijing is roughly around 300 air quality index and some video as well coming out of this region kind of images i should say to sha
