From the article you just posted:
"We need to have the testing available
because the big question now with COVID-19 is the denominator -- of anything," said Dr. Alex Williamson of the College of American Pathologists. "How many people get it? How many people recover? How many are hospitalized? How many died? We don't know the true denominator. More testing is the most important thing we need to do."
Obviously, this is why this journalist is not a data scientist. You can't blame them though, they need a headline people want to read.
See little Billy...it is the denominator we are highly uncertain about. Back in first grade little Billy we learned:
See little Billy, since we are not testing everyone we are not counting all the people that should be part of the denominator. This is making the fatality rate seem much more scary than it would be if we were testing everyone. This has nothing to do with the numerator.
It will be ok little Billy.
You should take this as a lesson for when you are a big boy that so often journalist just don't know what they are talking about.
