Epidemiologists have been saying all along we need to take drastic measures that will last months or more, while those who are more economically focused are talking about "weeks".

Sure - there is a ton unknown about a new virus - but we shouldn't say epidemiologists "don't know" as they consistently stated:

* it spreads easily
* it kills a high percentage of elderly or those with pre-existing conditions.
* it isn't going to go away on its own, but hopefully warm weather will help
* it may mutate and come back worse
* it is going to overload hospitals if we don't level the curve.
* it is defeated by a vaccine, partial cure, or getting to a 60%+ infection rate across the population.
