The first person to be diagnosed with Ebola on American soil went to the emergency room last week, but was released from the hospital even though he told staff he had traveled from Liberia.
The patient identified as Thomas Eric Duncan, a 42-year-old Liberian national, went to Texas Health Presbyterian hospital with a fever and told hospital workers he had just arrived from West Africa, the center of the Ebola outbreak, but somehow doctors gave him an antibiotic and pain reliever and sent him home.
Duncan was not in isolation for three days. He was finally diagnosed five days after his first symptoms developed.
Doctors tell CNN he is now listed in serious condition.
In an interview with CNN's Erin Burnett, Dallas Mayor Mike Rawlings says the patient may have come into contact with up to 20 individuals.
Health officials in Dallas are monitoring at least five children who came into contact with Thomas Eric Duncan while he was contagious with Ebola.
Investigators at the Centers for Disease Control are scrambling to locate any individuals in Dallas who came into contact with Duncan once he became ill and are now at risk for infection.
This is not the first time the U.S. has responded to an outbreak of a lethal virus like Ebola.

Mortars were heard in Baghdad's green zone Wednesday, as U.S. forces continued to pound ISIS targets in both Iraq and Syria. The crucial nation of Turkey, which shares a border with both Iraq and Syria, has finally agreed to join the fight.
The man tapped by the Obama administration to coordinate the international effort against ISIS tells CNN's Elise Labott exclusively that the war won't be swift.
General John Allen says training Syrian rebels, who are key to fighting the terror group on the ground, is going to take a long time.
"Over the long-term, the intent is to build credible forces, vetted forces," Allen told Labott. "We have been saying that all along, it is going to take a while. It could take years actually... and so we have to manage our expectations."
As for Iraq, it doesn't look like the fight against ISIS there will end anytime soon either.

Atlanta (CNN) - It's a lapse that has Americans concerned and health officials asking how it could happen.
A man who had Ebola but didn't know it walked into a Dallas emergency room September 26. Although his symptoms could have indicated Ebola among other things, no one at the hospital asked him if he had recently traveled, a source close to the case told CNN.
The man, who had just flown from Liberia to the States didn't offer the information either, the source said, and the man left the hospital. A spokesman for Texas Health Presbyterian Hospital says it's investigating whether he was questioned.
Regardless, two days passed between the time the man left and then returned to the facility September 28 where it was determined he likely had Ebola and was isolated. He tested positive Tuesday, health officials said.
The CDC advises that all medical facilities should ask for patients with symptoms consistent with Ebola for their travel history. It's possible others were infected because of the lapse.
Virginia authorities are investigating a possible link between the man accused of abducting Hannah Graham and at least three other cases of young women either murdered or missing.
The investigations include a cold case that involves a 23-year-old, who vanished near Liberty University in 2009. It's the same school where Jesse Matthew was once a student and accused of sexually assaulting another student 12 years ago.
