COVID-19 Outbreak (Update: More than 2.9M cases and 132,313 deaths in US)

True, but I rarely have seen people use that version of mortality rate. Most people when they say mortality rate, they mean as a percentage of cases, not overall population.

When having a discussion it's good to be sure both sides agree on what the discussion pertains to.

I agree that we need to be on the same page for discussions. At the same time we should be using correct terminology because it causes confusion. Since he was talking to an EMT the assumption should be correct terminology. The media has been terrible about this though. As usual.
