Two patients in Kentucky with Ebola-like symptoms have been quarantined for examination.

After the first case of Ebola was diagnosed in the US, doctors say they don't want to take any risks even though the two patients in Kentucky tested negative for the infection.

"The business of detecting it and finding out what it is, we're in good shape. If we get cases we need to be working more closely with the hospitals to see how we will manage individual cases," said Dr. Rice Leach, commissioner of health at the Fayette County Health Department. " But where did you get it, what is it, and who did you give it to? So far we're in great shape because we've practiced this thing three times going back as far as Anthrax, H1N1 and vaccine shortage 10 years ago."

Doctors will be taking every precaution necessary when it comes to patients who suffer Ebola-like symptoms.

Officials confirm the man diagnosed with Ebola in Texas Wednesday went to a Dallas ER in last week and, despite telling the hospital that he had been in disease-ravaged West Africa, they sent him home with antibiotics exposing him to dozens of people before he was brought back in, tested and diagnosed.

The hospital in Dallas released a statement saying it shows how easily an infection could be missed.

Now, about 80 people are being monitored for symptoms, that includes the 12 to 18 people who first came into contact with the infected man, as well as others those initial people had contact with.

The United Nations said Wednesday a staff member in Liberia died from "probable Ebola."
