Current deaths in the USA - 695 Current recovered - 370 Cases without outcome - about 52,300. Just under 1200 of those are serious cases
Take a look at all of the graphs. Total cases, total deaths, new cases per day, new deaths per day. All those graphs are on linear scales - but the values being graphed are not rising linearly.
The number of “cases” is without a doubt higher than 54,000. As that number goes up, the fatality rate goes down. There’s 54,000 positive test results.
Not to mention, it takes a couple days to go in the "died" column, but a couple weeks to go in the "recovered" column. So that number will also lag in the calculations.
