Infowars...
Two words, Bull and Sh*t
In this day and age, it would be impossible to cover it up. People would be running to Facebook, Twitter, and the local media to report their family had Ebola. While it would be possible to make one or two people "disappear," especially if they had no real contacts, it would be impossible to cover up dozens if not hundreds.
And "Ebola-like" does not mean Ebola. There are dozens if not hundreds of diseases which cause similar symptoms but are not Ebola or anywhere close to it.
