Mortality ratio oversimplifies the complexity of the reality (eg., the healthcare capacity vs the number of cases), and do not take into account the lag between a case identification, and lethal effect. It may, however, be of interest to some, and due to the lack of such a map on the internet, I have decided to plot mine. It does not slice data for the temporal dimension (yes, yet another possible weakness of these plots), but it was not my intention to depict it. Rather, I was interested in any differences might be found in total numbers. They were depicted in Figure 1 and Figure 2. I used the data from https://www.worldometers.info/coronavirus/. This is simple death/cases ratio.
It is apparent, that Central and Eastern Europe mortality ratios remain lower. That may, of course, stem from plethora reasons: differences in reporting, differences in dealing with the crisis, differences in social distance and/or law requirements, and so on. These reasons may, or may not be connected to the real mortality ratio, which is for sure unknown; we are able only to roughly estimate it.
Figure 2, on the other hand, shows differences in the recovery ratio. Some countries seem to deal with a greater ratio of the cases, than the others, in case of recoveries. Such countries seem to be: Germany, Switzerland, Austria. This supplements the first figure with some basic information about healthcare support to keep mortality low. But it does not reveal, how other countries, (CEE ones), are distinct in their low mortality ratio. One possible explanation is, that these countries yet have to face an increase in mortality. The other would be poor reporting. Or maybe…?
