So you're the expert now? I think I'll trust the CDC and WHO than some random Joe on a forum.

At the moment I type this, there are 205,452 confirmed cases with 8,248 deaths. That's more than 4% fatality rate. Even if we assume 4 times as many unreported cases, that's still 1% or 10x higher than the flu which is at .01%.
Death rates vary significantly by country and age. Italy is getting hit hard due to lower capacity of beds and an older population, compared to Germany who has a very low death rate so far.
You're right that we don't have enough information which is exactly why we need to assume the worse case scenario instead of wishfully thinking this is like a flu. All the medical experts are saying don't take the chance and stop trying to downplay it.
