Since Ebola arrived on American soil, the public has been bombarded with a series of facts and fictions about the virus. As a result, people are on edge, not knowing what to believe. Many are worried.

But are these concerns rational?

To help answer these questions, ABC News Chief Health and Medical Editor Dr. Richard Besser moderated a Twitter chat this week. The goal was to help spread awareness about what's true about Ebola - and what isn't. Infectious disease experts from the Centers for Disease Control and Prevention as well as the Nebraska Medical Center joined the discussion, along with other doctors and members of general public.

Scroll through these eight tweets to learn the truth about Ebola:
