What they are saying
"there could be as many as 170,000 cases and 90,000 deaths by Dec. 15"
Fear-mongering at its finest. Great work. Trying to negate the facts emerging, that the numbers have been going down not up, with a purely speculative "statement" asserting over-the-top calamity "could" happen. Oh, and the bottom line of the message: we need an infusion of more money to combat this wave of doom ahead. Predictable.
I agree that "170,000 cases and 90,000 deaths by Dec. 15" sounds greatly out of proportion to the facts as we are aware of them. On the other hand, I feel highly skeptical of any suggestion that "the numbers have been going down not up." (Except in Nigeria. I have a new-found respect for Nigeria.) I'm aware of the big readjustment on the latest WHO numbers. I'm not sure that that says much, except to speak to the chaos in the medical world in Liberia.
Here's an analogy. I noticed long ago, that when I was looking at reports about major disasters, such as earthquakes, there would often be a large area, in the general center of the presumed disaster region, that had no reports of serious injuries or damage. I noticed long ago that that was not a good sign. It was a sign that things had been so thoroughly smashed that no information was being gathered and transmitted out.
So, we'll see.
