If one takes the statistics of the Diffs they are seen below:

The images below show the time series of confirmed cases (solid line) and deaths (dashed line) for representative countries and regions of the world. We choose these countries since they have large numbers of confirmed cases, and are expected to have a reasonably good accounting of the cases. The Diff is the approximate number of days prominent matching features in the time series (e.g. peaks, valleys and slopes) of the two cases. In many, but not all cases we identify the matching structures and the Diff in days. You can click on an image to blow up its size and see details.
