A deadly superbug may have infected nearly 200 people at Ronald Reagan ucla Medical Center. Seven people known to have been exposed since october. Two of them died. This morning the hospital is offering a free athome testing kit to people who may have been infected. Carter evans is at the Medical Center in los angeles with how this bacteria started to spread. Carter, good morning. Reporter good morning. And good morning to our viewers here in the west. As more people return their test kits, the concern is that the number of infections will increase. Meanwhile, the cdc and the l. A. Department of Public Health is investigating to determine exactly how so many people were exposed to this deadly bacteria. The drugresistant superbug known at cre has been blamed for the death of two patients in Ronald Reagan ucla Medical Center. At least five others have been infected, and Health Officials are trying to determine just how much patients may be at risk are exposure. The outbreak which was discovered last month is tied to a set of specialized endoscopic procedures which took place at the hospital between october of last year and january of 2015. Officials are now in the process of notifying 179 patients who may have come in contact with the bacteria. The hospital cleaned the scopes according to guidelines established by the manufacturer but the type of endoscope used in the procedure, which some estimates say is performed half a million time as year in the u. S. , can accumulate bacteria in spots that are difficult to disinfect. In a statement, the ucla Health System said the two scopes involved with the infection were immediately removed and theyre using a decontamination process going awe bov and beyond national standards. Cre is resistant to commonly used antibiotics in the same family the e. Coli. According to the cdc, once it enters the blood stream the bacteria can kill up to 50 of infected patients. Since 2012 superbug infections related to dirty endoscopes appeared in cities across the country, including chicago, pittsburgh, philadelphia and most recently seattle. We reached out to olympus medical systems the company that makes the endscope in question and havent heard back. The fda is working to determine what more could be done to reduce infections but right now says the benefits of the endoscope outweigh risks. Carter thanks. Also in los angeles our dr. David. Good morning. Good morning, charlie. How serious and what should we be worried about . Serious. The fifth major infection over of the last the two to three years and keeps happening. In this particular one, 179 patients exposed and what scares me they announced this happened end of january three weeks later notifying patients and sending them an athome kit. Sounds a little strange to me. Why did it take them so long . I dont know. Certainly thats worrisome, because this is a bacteria that can be on your skin and not cause a problem until it gets in the blood stream but you can spread it. Certainly identify individuals colonized, when on your skin early to get rid of it. How in the world has this happen at one of the best hospitals in the country . Its certainly an issue and i think goes back to this scope. This is a particular scope used predominantly in gallbladder and pancreatic procedures and has to curve to get around corners in the body. And those little corners, bacteria can accumulate and it either it wasnt cleaned well or the criteria for cleaning it are wrong and we need to certainly address that and there should be a red flag because this is several outbreaks that happened over the last several years and we have to have that red flag to make a change here. And doctor, a step back, too, and look at the larger issue of superbugs in hospitals and how we are going to change the way we treat patients and how were going to deal with these. Yeah. Superbugs are a major problem that is growing. Ke did a story together a few months ago about for the first time now we have hope with new antibiotics that attack superbugs. Until theyre on the market its a major issue. Witness you have one of these particular bacteria it is very difficult to treat it. So we need to limit the antibiotics we use and obviously do simple things like washes the hands and washing these scopes and really taking caution so as not to spread it. All right, very scary stuff. Thank you very much. Much of the west can expect one more day of unusually high temperatures but the other twothirds of the country is waking up this morning to brutally cold weather.

This morning a white house summit on fighting violent extremism enters its third and final day. Yesterday president obama addressed dignitaries from 60 countries. He calmed on Muslim Leaders in particular to confront twisted ideologies that groups like isis use to radicalize young people. We are not at war with islam. [ applause ] we are at war with people who have perverted islam. No religion is responsible for terrorism. People are responsible for violence and terrorism. A new cbs news poll shows isis as a major threat. 6a 65 now compared to 58 in october. Most americans favor sending Ground Troops to iraq and syria to fight isis. That snub at 57 versus 47 four months ago. Senior contributor michael morale in washington good morning. Good morning. You heard people faulting president obama for failing to identify this as islamic extremism. Do you think this is a pseudocontroversy over semantics or is this a failure to properly identify the enemy . Norah, i understand what the president is saying and i agree with it. We do not want to create the perception that we are at war with a religion. But the reality is that al qaeda and isis believe they are religious warriors. They believe that they are fighting on behalf of their religion, for their religion. Its not rhetoric on their part. They really believe it. For the first time as norah just pointed out, the poll says the majority of americans are now in favor of Ground Troops. Youve said we really cant succeed without them. How likely is that to happen . I think we need Ground Troops fighting isis in both iraq and syria. The best outcome would be that the Iraqi Military would be that ground force. The second best outcome would than it would be a Regional Force of arab countries, and only as a last resort i think should we put american Ground Troops in, but we need Ground Troops. In the meantime how significant are isis gains in solidifying their position . So theyve solidified charlie, their position in two places. One is in iraq and syria. Their spread has been stopped but theyve solidified their position in the areas that they coal. There were some cities they did not control early on they control them now and the second is the spread of their brand across a number of countries now. Algeria, libya, egypt, yemen, afghanistan. And thats scary, because it makes those groups more dangerous. The group we saw in tripoli that killed an american. The group we saw in in Eastern Libya that did those terrible beheadings. It makes those groups more dangerous. Is it possible they could win the allegiance of all of these groups and therefore have a united front . I think thats one of the things we have to worry about and i think thats why we have to do two things here. Weve done a very very good job at defending ourselves against terrorist trying to kill us. We have not done a good job at the president s talked about, not done a good job at stopping the creation of new terrorists. We have to deal with that much bigger problem. Michael morale thank you so much. An american victim of isis remembered in her home town. Hundreds gathered by kandcandlelight to honor kayla mueller.
