We are far from finished with Ebola outbreak.

Yes, but we are working on epidemic modelling, so we are not concerned

Working as you are paid for it ? If yes then please by all means go on. I am not against anyone working on rare problems, rare problems do matter and of course I hope a cure is found to this awful disease that claimed thousands of lives as well to any disease that kills people worldwide.
