Ebola isn't contagious until symptoms appear

"Individuals who are not symptomatic are not contagious."
 "I want to emphasize that Ebola isn't contagious until symptoms appear."
--http://www.cdc.gov/media/releases/2014/t0728-ebola.html

"Ebola symptoms can include fever, muscle pain, vomiting and bleeding and can appear as long as 21 days after exposure to the virus. The disease is not contagious until symptoms begin, and it takes close contact with bodily fluids to spread."
http://www.usatoday.com/story/news/nation/2014/10/01/texas-ebola-patient/16525649/

"The incubation period, or the time interval from infection to onset of symptoms, is from 2 to 21 days. The patients become contagious once they begin to show symptoms. They are not contagious during the incubation period."

"The only way that an individual can contract Ebola is by coming into contact with the bodily fluids of someone who is exhibiting symptoms."

"Authorities say people with Ebola are contagious but only through contact with infected bodily fluids when they are showing symptoms of the virus. Those symptoms include high fever, severe headache, diarrhea and vomiting, among others."

"People who have Ebola are contagious -- but only through contact with infected bodily fluids -- when they display active symptoms of the virus, such as a high fever, severe headache, diarrhea and vomiting, among others. It's not like a cold or the flu, which can be spread before symptoms show up, and it doesn't spread through the air. "

"Ebola isn't contagious until symptoms appear, and then it can spread only by close contact with a patient's bodily fluids."

If you repeat something enough times, it must be true right?  Has there been a study?  Where is a link to it? Who authored it? I just write a blog that no one ever reads but I always link to my sources.  I'm calling BS.  Ebola is extremely contagious and even health workers and doctors, who presumably know a thing or two about infection, have caught it and died.  If you can't point to a peer-reviewed study that makes that finding, then shut up and stop spreading disinformation.
