"His symptoms included fever, vomiting and diarrhea, the sources said. "
This being flu season it paves the way to lock up half the Country. Same symptoms after all.

This man has been given the all-clear, even though he just got to the hospital today. There's no way they can say for certain whether or not he has Ebola, given that reliable tests for that disease takes several days.
What are they trying to hide?

I certainly won't be going to any airports. If I needed to I wouldn't go home to my children.

No he would have been under the impression Nigeria was ebola free.
Or are you saying no one should go to airports?

NYC is also running ebola drills having people walk into hospitals with Ebola-like symptoms and claiming to have returned from West Africa.
Thomas Ksiazek, a professor at the University of Texas Medical Branch at Galveston who has done extensive research on Ebola, says that testing is done using a process called real-time RT-PCR, or reverse transcription polymerase chain reaction. In this technique, doctors or medical personnel take samples of blood from a patient. They then add an enzyme to convert RNA found in the blood into DNA (RNA is a chemical messenger that helps turn DNA’s “instructions” into proteins). Next, a “primer” is added that targets a string of genetic code unique to the Ebola virus. The concoction is then run through a PCR machine, wherein that strand of Ebola genetic material is amplified, or copied, many times (if it’s there, that is. If it’s not, nothing happens and the test returns a negative.)
Finally, a chemical probe is added that binds to these snippets of DNA and alerts the scientists to the presence of the Ebola virus, Ksiazek tells Newsweek. The whole process can take as little as three to four hours.
A technique called ELISA can also be used to diagnose Ebola, but it takes longer and also requires at least 100 times more individual viruses for an accurate result to be obtained than RT-PCR—meaning it is less sensitive, and doesn’t catch the virus as soon as the latter technique, Ksiazek says. The PCR technique was first widely used to diagnose Ebola in 2000. Several groups of researchers are working on even faster, more portable tests, using disposable materials resembling home pregnancy tests, Science magazine reported last week. Two of the diagnostics will be tested in the coming weeks.
