No, I am not about to embark on a paean in praise of the Nigerian state health system. That would be both dull to read, and an insult to the millions of Nigerian who have to suffer it every day. For the main credit goes to a single doctor working in a private health clinic, Stella Adadevoh, who effectively saved the country from disaster by spotting that its first Ebola patient was lying about his condition, and then stopped him leaving her clinic. Dr Adadevoh is now dead, having acquired Ebola herself in the process. But more on her later. First, let me explain why Nigeria was quite such a "perfect storm" for Ebola in the first place.
