I don't see anywhere in that article where the death rate is discussed. So I'm guessing you are just multiplying the two numbers together without understanding what they actually mean (similar to what the doctors in the video do).
As the article you linked points out:
> Some people diagnosed as asymptomatic when tested for the coronavirus, however, may go on to develop symptoms later, according to researchers.
Additionally, what contact tracing is being done means that there are some asymptomatic people being tested who do show up in the confirmed cases.
By source, I really meant someone with some epidemiological training. I think you will be hard pressed to find anyone with bottom range estimates below .1% and given the numbers in NY, I doubt NYs death rate can realistically end up below .5%
Couple of their quick mental math when asked questions were wrong but most of it is sane and matches other sources.
