know more than 200 people have been injured by the tornado. Now we'll take you inside the hospitals treating them. Doctors working around the clock. Abc's alex perez shows us why the doctors are saying this tornado is one of the worst disasters they have seen. Reporter: I am at integris southwest medical center here in oklahoma city, and it has been a manic 24 hours for doctors and staff here in the emergency room. They are racing to keep up with the tornado victims. They've seen 91 patients here alone. Dr. David hogan has treated the majority of the 91 patients who began streaming in here yesterday evening. What's the most severe you've seen? People having things blown into them, or them being picked up and thrown. Rter: Hogan is used to crises. He treated victims of the oklahoma city bombing, and the deadly 1999 tornado. He says in many ways this tornado is worse. R.. We are commonly seeing our populations injured by much more powerful tornadoes than in the past. Reporter: Jackie raper is among those who was rushed to the hospital. She didn't think she would live to tell her story. Ribs are cracked, my sternum is fractured. Reporter: She and her two neighbors huddle in the bathroom, the safest room in the house. But, within seconds the entire the roof was gone and debris was flying everywhere. I'm sure it didn't last as long as we thought, but it was quick. Reporter: Raper lost everything she owns, but says seeing those neighborhood schools, where she's spent so much time over the years, flattened, that's the part she can't accept. Hey, I am alive, and there were little children that aren't. And I just can't imagine people having to go and not find their child at school. Reporter: And jackie raper says she still has a lot of fight left in her. The good news is that doctors here say the majority of the injuries they're seeing are not life-threatening. Thank you so much, alex.
