If they have actually seen these 3 drugs work, why spend a lot of time setting up prolonged trials (mentioned in article)? If you have an epidemic with no "known" cure why would you not start using a know med in mass if it showed some early signs of success? I'm sure there are a lot of folks in Italy that would gladly take any of the 3.
