Yes, the closed cases has been steadily dropping but remains well above 2% - however, we expect that number to be higher than the actual mortality rate while the infection is still spreading/growing, as recovering from the disease takes longer than dying from it.

What I find more concerning is that the current ratio of deaths to cases is 3%, which I would expect to be an underestimate. Hopefully this is due to under-reporting of the mild cases, but it does imply either a major under-reporting of active cases or a significantly higher mortality rate than has been estimated so far (most likely the former).
