When I told people earlier this month that I was off to West Africa again to cover the Ebola outbreak, the resounding response was, "Isn't that over yet?
The short answer is no, but there is a lot more to it than that.
The outbreak has been "nearly over" for months. So while "Ebola fatigue" is understandable, it's also potentially extremely dangerous.
There are still around 20-30 new cases a week in the three worst-affected countries.
Before this outbreak, those numbers would have constituted a major epidemic, but we live in very changed times.
At the height of the outbreak, West Africa was seeing hundreds of new infections a week.
But it only takes one new infection to spark a massive epidemic.
Desperation
As you walk around Sierra Leone's capital Freetown, you feel the desperation of a city willing with all its might for the end to Ebola in its midst.
