It's no claim, if you doubt it you can confirm with the W.H.O.
My point is that it has gotten into Lagos and it was contained so if there is any doubt if they have the ability to contain it, I guess they have been able to prove that. The difference with Nigeria is that the citizens seem to understand how serious this is and they are cooperating with authorities and that is why it didn't get worse than this. Don't forget that what we are witnessing now with the other three countries started from just one case of Ebola.
