Tonight, we have some extraordinary reporting from inside the hot zone. ABC's chief medical editor Dr. Richard veser managed to gain access to the heard of the fight to stop the ebola virus. What they found is truly shocking. He's witnessed all manner of medical emergencies, but this one he's calling "The Gates of hell." Reporter: I'm on my way to one of the most dangerous places on Earth. We're headed straight into the heart of an ebola outbreak, the worst the world has seen. A virus that kills up to 90% of those it infects. Reporter: This is JFK hospital, one of only a handful of ebola clinics in Liberia. We're going into the triage unit here where they sort out whether a patient has ebola or somethings else. It's a grim purgatory for sick patients. They wait here to find out if they test positive for ebola. Some will be moved into the isolation ward. Others have to wait. In the fight to contain the virus, health care workers face great risk every day. Two doctors in this hospital have already died. So many health care workers have gotten ebola. Does that worry you? Yes, it worries me. Reporter: In this dangerous battle, doctors here have shockingly few resources. Some are forced to rely on makeshift contamination suits. So we're going into the ebola ward. The final part is put thing hood on, but they don't have hoods ready made, so they're making them out of other equipment. The protective hoods that would keep them safe, this would cost $1.50, but supplies are scarce. Simple bleach is a lifesaver. This is where they're getting sprayed down after leaving the unit. If it isn't done properly, this is where they can get contaminated. Ebola is spread through bodily fluids. Symptoms begin with fever and body aches. In some, severe blood loss and organ failure. Death can come quickly, often with days. Patients in here are the lucky ones. They have doctors and medical care. Occasionally, a survival story. How are you doing? Is she doing well? This woman is one of the few who recovered from ebola. How long has she been at the hospital? How many days? One week, one day? How do you feel today? I'm jumping. Reporter: But the JFK clinic is overcrowded and overwhelmed. Doctors must turn away potentially infected people every day. Outside the unit, patients are waiting. They think they may have ebola. They watch as ten bodies are removed from the ebola ward. This is incredible. Seeing the truck cart away ten bodies of people who died from ebola. I can't imagine what someone is thinking, who has arrived there for treatment. You know, it's the Gates of hell, going into that treatment ward and knowing the odds are you're going to come out in a body bag. For the past five months, ebola has ravaged western Africa. 1400 have been reported dead. 2600 infected. The outbreak has struck several countries. The worst of it here in Liberia. A ground zero for the epidemic. Here, a haunting question -- is it too late? In the capital, chaos and panic is leading to desperate measures. Unable to control ebola's spread, last week the government quarantined an entire slum, home to 75,000 people. As the quarantine orders sparked riots, residents were unable to leave, forced to rely on the government for food and water. ABC news has been reporting from the center of the outbreak since it began. They're checking who can come in and out. Only people with medical supplies can come in and out. Reporter: This is the part of the city that's been quarantined. It's where there's been the most ebola and they're not letting people in and out of the area. Fences keep thousands inside the slum. They've been in this compound for seven days? Eight days. Reporter: Why? We are quarantined. Reporter: It's like you're in prison? Inside the isolation zone, we spy a young man she had met before the quarantine. Steven, I'm Dr. Richard, ABC news. How are you doing? Steven is a 30-year-old man from west point. His father, sister and two brothers all contracted ebola. Normally you got somebody sick you can go to the hospital and visit them. How do you feel knowing you can't see them? Reporter: Although Steven lives in west point, he had taken to sleeping in a Taylor shot to avoid getting the virus. But in a stroke of bad luck, he was inside the slum when the quarantine took effect. We got special permission for Steven to cross the barrier to speak with us. In this section, it's no more than a simple piece of rope. How many people have you lost from ebola? What's the solution? How will ebola end? I don't see we are doing enough. The best solution now I think for me is to get a way out. Reporter: He's now forced to cross the rope line back into the ebola zone. I've seen outbreaks all over the world and I've never seen anything like this. It makes no sense in terms of disease control. This is just adding enormous pain and suffering. In this dark area, an influx of help from abroad is a rare ray of hope. A new center is set to open its doors as soon as tomorrow. Modern, clean and capable of holding up to 400. For so many people here, these effort also be too little, too late. And many people wonder what might have happened had the world acted sooner? I'm Dr. Richard Besser in Liberia. We want to thank Dr. Besser and our producers for their amazing and dangerous work tonight.
