"estimated"
We just don't know yet. The worldwide death rate could be higher, or lower. Currently in the US, the death rate would seem to be about 2.4%, assuming I can do math. But it will take more testing to get a better handle on the actual numbers in the US, so we don't have to rely on estimates from *experts* such as yourself, or me.
I think right now there's the possibility that some deaths attributed to it, aren't related. At the same time, there could be some deaths caused by it, that have not been attributed to it. I've heard stories, which I haven't bothered to verify, that all deaths in Italy have been attrivuted to the virus.
That could go a long way towards explaining what you posted about Italy.
But none of that can take into account the total BS China has fed the world in terms of how many cases and deaths they've suffered. We'll probably never have accurate numbers from China.
And since I'm chiming in when it probably should be Danzinger, I'll throw this in for effect: get a job, ya lazy snowflake!
